Progressivism

Into the 21st century and social democratic turn

Influence of the Nordic Model

Many analysts have noted that 21st-century progressivism has focused on tax-funded social benefits inspired by the Nordic model, noting Bernie Sanders as an example of this advocacy and policy approach. Norway's progressive tradition has roots that reach back even before the modern welfare state. In 1884, 171 prominent Norwegian figures, including five future prime ministers, helped establish the Norwegian Association for Women's Rights. The organization campaigned for women's access to education, the right to vote, the right to work, and greater equality between men and women. These efforts helped establish women's equality as an important part of Norwegian political life. By the 1970s, gender equality had become an increasingly important part of government policy, with the state creating institutions to promote equality and combat discrimination.

Einar Gerhardsen was a central figure in the development of Norwegian social democracy. After beginning in the socialist labour movement and briefly aligning with its communist wing, he and the Norwegian Labour Party pushed for reform-minded democratic socialism. His political rise was interrupted by the German occupation, during which he became involved in the resistance, was arrested and tortured, and spent much of the war imprisoned in Norway and Germany. After liberation in 1945, Gerhardsen helped lead the country through reconstruction, serving several terms as prime minister. Under his leadership, Labour governments expanded state regulation, industrial development, progressive taxation, redistribution, and social security. These policies helped reduce poverty and unemployment while laying much of the foundation for Norway's modern welfare state. Gerhardsen's legacy therefore came to represent both democratic government and greater economic security and social equality.

International organizing

Founded in Leipzig, Germany, on May 22, 2013, the Progressive Alliance is an international political organization made up primarily of social democratic political parties and organizations. The organization was established as a substitute for the already-existing Socialist International, of which many of its constituent parties are either present or previous members. In January 2012, Sigmar Gabriel, then chairman of the Social Democratic Party of Germany (SPD), decided to terminate the SPD's annual membership fee of £100,000 to the Socialist International. Gabriel criticized Socialist International for admitting and maintaining undemocratic political movements, leading to the establishment of the Progressive Alliance. The organization has a stated goal to become the worldwide network of "the progressive, democratic, social-democratic, socialist, and labour movement."

In May 2020, Progressive International was formally founded and launched on 11 May 2020, responding to a 2018 open call by the Democracy in Europe Movement and the Sanders Institute for united progressive forces around the globe. The open call was echoing two twinned appeals published in 2018 by U.S. senator Bernie Sanders and Yanis Varoufakis, who is a Greek economist and self-described libertarian Marxist, to form an international movement to combat the rise of hard right authoritarianism and potential neofascist global influence represented by U.S. president Donald Trump. PI's founding was supported by a group of 40 advisors including Ece Temelkuran, Katrín Jakobsdóttir, Yanis Varoufakis, Carola Rackete, Nick Estes, Vanessa Nakate, Noam Chomsky, Arundhati Roy, Naomi Klein, Niki Ashton, Rafael Correa, Fernando Haddad, Celso Amorim, and Alvaro Garcia Linera. PI seeks to combat authoritarian nationalism around the world and is opposed to what it describes as disaster capitalism.

Europe

Norway

Rather than viewing economic growth and social welfare as competing goals, Norwegian governments have generally attempted to combine a productive economy with a strong social safety net. After Gerhardsen, the next major transformational stage in the development of Norwegian social democracy was associated with Gro Harlem Brundtland, who followed Gerhardsen's generation and became Norway's first woman prime minister. Brundtland served three separate periods as prime minister: briefly in 1981, from 1986 to 1989, and again from 1990 to 1996. Her long political career made her an important symbol of women's increasing participation in Norwegian political life, and she became affectionately known as Landsmoderen, or "Mother of the Nation." Brundtland represented a somewhat different form of social democracy from the industrial-centered model associated with the early Labour governments. During the economic difficulties of the 1980s, Norway faced problems including falling oil prices, economic stagnation, and pressure on government finances. Brundtland responded by accepting some market-oriented reforms rather than attempting to preserve a completely state-directed economy.

Gender equality was also central to Brundtland's political approach. In 1986, she appointed a cabinet in which approximately 40 percent of the ministers were women, a remarkable change for the period. Her governments expanded paid parental leave and developed state-supported childcare, helping make it easier for both men and women to participate in the workforce. These policies reflected a broader idea that gender equality was not simply a question of individual rights. It was also connected to the economy because a society that enables women to work and pursue careers can make fuller use of its population's skills and abilities. Brundtland also helped connect Norwegian social democracy with the growing environmental movement. As chair of the United Nations World Commission on Environment and Development, she led the work that produced the influential 1987 report Our Common Future. The report helped popularize the modern concept of sustainable development, arguing that economic development should meet the needs of the present without preventing future generations from meeting their own needs. This approach connected three goals that had often been treated separately: economic growth, social equality, and protection of the environment. Brundtland helped broaden the meaning of Norwegian social democracy and expand it toward more inclusive capitalism.

The Labour Party continued to change after Brundtland's era. Jens Stoltenberg, who served as prime minister from 2000 to 2001 and again from 2005 to 2013, represented a more modernized form of social democracy sometimes associated with the Third Way. Like other center-left leaders of the period, Stoltenberg placed greater emphasis on economic efficiency, international competition, and the use of market mechanisms. His governments continued the movement toward partial privatization and reform of some state-owned enterprises while maintaining Norway's extensive welfare system. Norway had discovered large quantities of oil in the North Sea beginning in the late 1960s, creating enormous potential wealth. Rather than spending all of the oil revenue immediately, Norway placed much of it into a sovereign wealth fund. The fiscal rule established a framework for determining how much of that wealth could be used in the national budget, helping prevent the economy from becoming overly dependent on oil revenue and preserving wealth for future generations.

The next major phase came under Jonas Gahr Støre, who became prime minister in 2021. Støre inherited a country with a highly developed welfare state and substantial wealth, but also faced new challenges. These included concerns about economic inequality, the future of the welfare system, and the growing urgency of climate change. His government presented itself as seeking a more equitable economic model, with greater emphasis on reducing inequality, protecting workers, and maintaining accessible public services. Støre's approach has placed particular emphasis on finding a balance between economic security and environmental change. Norway remains a major producer of oil and natural gas, so moving toward a lower-emission economy presents a difficult challenge. Støre has sought to reduce emissions while also protecting employment and preventing greater inequality. His government has therefore treated the transition toward a lower-carbon economy as a process that should create new industries and jobs rather than simply eliminate existing economic activity.

Norwegian social democracy continues to be shaped by debate within the broader left. After the 2025 parliamentary election, Labour remained the largest party in a left-leaning bloc but depended on smaller parties such as the Socialist Left, Greens, and Reds, which generally press for stronger climate policies and greater economic redistribution. Major disagreements include oil policy, with Labour supporting continued petroleum production while parties farther left advocate a faster transition away from fossil fuels, as well as taxation and investment, where smaller left-wing parties favor greater redistribution and, in some cases, tighter ethical restrictions on Norway's sovereign wealth fund. While Labour currently occupies a relatively moderate position compared to its historically economic progressive legacy under Gerhardsen, socialist and Green parties continue to push for a more expansive social democracy encapsulated by stronger environmental and redistributive policies.

Norway's commitment to equality continued to expand beyond economic class. Beginning in the second half of the twentieth century, Norwegian governments increasingly adopted legal protections against discrimination based on factors such as ethnicity, religion, disability, and sexual orientation. Gender equality also became firmly established in Norwegian law and public policy. Norway's progressive approach to LGBT rights developed alongside these broader changes. The country became an early leader in legal protections for gay and lesbian people. In 1993, Norway established registered partnerships for same-sex couples. In 2008, the Storting approved a common marriage law for same-sex and opposite-sex couples, which took effect on January 1, 2009. The law gave same-sex couples the same legal right to marry and also expanded their rights concerning adoption and assisted reproduction. Later legislation further strengthened protections against discrimination based on sexual orientation, gender identity, and gender expression.

United Kingdom

20th century progressivism in the United Kingdom highlights enduring tension and factionalism between more avowedly left-wing progressives and those who incorporate more syncretic politics into their progressivism. Groups like the Institute for Public Policy Research, the Fabian Society, and Progressive Britain are organizations represent a wide variety of U.K. progressive thought. Progressivism in the United Kingdom has seen shifts from New Labour's early dominance to the rise of cultural liberalism, environmentalism from the Green Party, and grassroots democracy movements with a variety of focuses, including pro-Palestine anti-war causes, radical democracy, and universal basic income. Tony Blair's government represented a significant period of progressive growth, although his politics were more centrist than previous progressive movements that leaned further left, and his government faced criticisms for its Third Way market-oriented policies and emphasis on deregulation. The Blairite consensus was dominant within U.K. progressivism from the mid-1990s and through the end of Blair's premiership, which ended in 2007. New Labour continued to evolve with the subsequent Labour leadership of Gordon Brown and was formally abandoned by his successor, Ed Miliband, for One Nation Labour in 2010.

Jeremy Corbyn represented a staunch return of the Labour party platform to its more historic democratic socialism with a focus on nationalization, robust public spending, and both anti-austerity and anti-war stances. Corbyn appealed to a progressive left base disillusioned with previous Labour governments, but he was a controversial figure in the party who oscillated between a loyal base of support and electability concerns. Subsequent leader and eventual prime minister Keir Starmer shifted Labour toward pragmatic, economically cautious centrism, striving for electability by striking a balance between broad public appeal, traditional Labour beliefs, and Starmer's own conviction that economic changes made previous more left-wing economic positions untenable.

The animosity between Corbyn and Starmer intensified with Starmer's suspension of Corbyn from Labour in 2020, accusing Corbyn of an inadequate response to antisemitism. Corbyn was supported against these accusations by Progressive International. Starmer said in 2023 that "the very best of progressive politics is found in our determination to push Britain forward," but "there are precious things – in our way of life, in our environment, in our communities – that it is our responsibility to protect and preserve and to pass on to future generations. If that sounds Conservative, then let me tell you: I don't care." Corbyn supported the foundation of the socialist Your Party in 2025 with Zarah Sultana in a further schism for U.K. left-leaning progressive politics. Facing challenges from Brexit and increased right-wing presence, contemporary progressivism in the United Kingdom can be characterized by increasing cultural liberalism and factionalism surrounding the role of capitalism in society. Starmer was viewed largely unfavourably by the British public during his tenure as prime minister. His net approval rating began slightly positive, declining over the course of his premiership to an average of −46% by November 2025. By the end of 2025, opinion polls rated Starmer as one of Britain's most unpopular prime ministers, being compared to Liz Truss. Labour's losses in the local elections in May 2026 and discontent over policy led to calls for Starmer to resign as leader, and to the resignation of several members of the government, including Health Secretary Wes Streeting.

Andy Burnham, who at the time was mayor of Greater Manchester and cited as Britain's most popular politician was blocked by Labour's National Executive Committee from running in the 2026 Gorton and Denton by-election. On 18 June 2026, a by-election was held in Makerfield after sitting MP Josh Simons resigned to allow Burnham to stand for a seat in Parliament and potentially challenge Starmer for the Labour leadership. It was the first time since the 1965 Leyton by-election that a by-election was caused to provide a vacancy for a person not currently in Parliament. Burnham won the by-election with almost 25,000 votes and a majority of over 9,200 votes. Four days following the election, Starmer announced his resignation, leading to a leadership election. After being nominated by over 90% of Labour MPs, Burnham was elected unopposed as leader, becoming prime minister on July 20, 2026, as the first Labour and Co-operative Party MP to hold the post. Burnham has been cited as pushing a more progressive and left-populist agenda in his premiership than Starmer especially regarding Burnham's noted preference for market socialist policies.

Latin America

Argentina

Kirchnerism in Argentina refers to the political strategies of Néstor Kirchner and Cristina Fernández de Kirchner, who were successive Presidents of Argentina. In favor of his wife, Néstor Kirchner chose not to run for reelection in 2007 after taking office on May 25, 2003. After Isabel Perón, Cristina Fernández de Kirchner was the first woman to be elected directly to the presidency of Argentina. Cristina Kirchner has led the Justicialist Party since 2024. Kirchnerist policies are labeled Peronist, progressive, and left-wing. Social services were sponsored by Kirchnerist administrations, which were perceived as blatantly anti-neoliberal. Some political scientists propose the term "Pink Tide neopopulism" to characterize movements that are regarded as a response and a counter to neoliberalism. This is in contrast to the neoliberal populism that was prevalent in the 1990s. Kirchnerism is seen as a response and a counter to neoliberalism. Healthcare and income transfers were greatly increased, most notably by giving 15 million people—roughly 41% of the country's total population—free prescription drugs. Kirchnerists also adopted the traditional Peronist strategy of endorsing wage hikes and participating in labor battles. Argentina's period without widespread strikes during the Kirchnerist governments was only surpassed by the 1946–1955 era of Perón’s government.

Brazil

Lulism in Brazil demonstrates the broad coalitional and reformist nature of contemporary progressivism. Luiz Inácio Lula da Silva's 2022 presidential comeback campaign was a progressive resurgence narrative focused on the working class and anti-corruption, running against incumbent right-wing populist President Jair Bolsonaro. Lula was 17% ahead of Bolsonaro in a poll in January 2022 in what was seen as an early sign of shifting progressive sentiment in the voting population against far-right politics of the Bolsonaro government. In the first round of the presidential election, Lula was in first place with 48% of the electorate, qualifying for the second round with Bolsonaro, who received 43% of the votes. Lula was elected in the second round on 30 October with 50.89% of the vote, the smallest margin in the history of Brazil's presidential elections. Lulism features an overlaps in political parties, including the Workers' Party founded by Lula. While seeing a democratic socialist society as the ultimate goal, Lula has called for a reformist "social liberal" approach to begin resolving poverty gap while acknowledging the reality of existing market structures.

Mexico

Described as a social democratic progressive and left-wing populist, Andrés Manuel López Obrador, or AMLO, was a national politician for over three decades, and ultimately elected President of Mexico following a 2018 landslide victory. López Obrador has been characterized as the "ideological twin" of Bernie Sanders and Jeremy Corbyn, and Corbyn invited López Obrador to the Parliament of the United Kingdom. After winning the 2019 election in Argentina, López Obrador formed a "progressive alliance" with President Alberto Fernández, as reported by El País, marking one of López Obrador's first official trips abroad to Mexico. During his presidency, López Obrador commenced a number of progressive social reforms and encouraged public investment in industries that had been liberalized by earlier administrations. His supporters commended him for reorienting the nation's neoliberal consensus toward bettering the working class's situation and for fostering institutional rejuvenation following decades of extreme inequality and corruption. While credited and praised by supporters for progressive reforms, López Obrador has also received criticism for illiberality and contributing to democratic backsliding.

One of López Obrador's first measures was to raise the minimum wage from MXN $88.36 to MXN $102.68, representing a 16.2% increase—the biggest since 1996. This revision had an immediate impact on average worker salaries, which increased by 5.7%. López Obrador executed his promised "Republican Austerity" upon taking office as well, which aimed to cut spending on political privileges and non-essential government products and services. He canceled presidential pensions and imposed a pay cap for government personnel, ensuring that no one could earn more than the president. López Obrador reduced his own compensation by 60% and chose not to live in Los Pinos, the expensive presidential complex with upkeep costs totaling around MXN $30 billion over the last two administrations. López Obrador auctioned away several government planes and helicopters including the presidential plane "José María Morelos y Pavón", for roughly MXN $1.658 billion. The auction revenues supported hospitals in Tlapa, Guerrero, and Tuxtepec, Oaxaca.

The AMLO presidency also aimed to streamline the bureaucratic structure of the Mexican government, which López Obrador characterized as benefiting elites and mismanaging public finances. The AMLO budgets often included spending cuts to various government agencies, including prosecutors and the public health system, leading to layoffs, salary reductions, and poorer services. To centralize operations and address the reduced workforce, López Obrador often utilized the military for infrastructure projects. López Obrador called for the removal of independent government bodies in February 2024, saying that they duplicated the work of some cabinet ministries, suggesting that their duties be taken over by the Mexican cabinet to save funds and promote government efficiency. The proposal faced widespread condemnation, including from opposition members who criticized it as retribution against autonomous agencies. In the same month, López Obrador successfully proposed a constitutional amendment requiring the minimum wage to consistently rise above the rate of inflation.

Claudia Sheinbaum, a member of the left-wing political party Morena, was widely perceived by her party as the frontrunner to succeed López Obrador, and she eventually received the candidacy of the ruling coalition, Sigamos Haciendo Historia. Xóchitl Gálvez emerged as the opposition frontrunner in Fuerza y Corazón por México. On October 1, 2024, Sheinbaum was sworn in as president, becoming the first woman and person of Jewish origin to assume the office. Ifigenia Martínez, president of the Congress of the Union and a noted figure for the Mexican left, awarded her the presidential sash. The Federal Telecommunications Institute (IFT), the Federal Economic Competition Commission (COFECE), the National Institute of Transparency for Access to Information and Personal Data Protection (INAI), the Energy Regulatory Commission (CRE), the National Hydrocarbons Commission (CNH), the National Council for the Evaluation of Social Development Policy (CONEVAL), the National Institute for the Evaluation of Education (MejorEdu), and the Federal Economic Competition Commission were among the seven autonomous agencies that Sheinbaum consolidated into executive authority. Critics claimed that the measure compromised openness, regulatory independence, and limits on executive power. On 5 February 2025, Sheinbaum offered a constitutional reform to Congress prohibiting immediate reelection and barring family members of sitting officeholders from campaigning for the same public offices. The Senate delayed implementation of the reform until 2030. The bill was published on 1 April.

North America

Canada

While not a member of the Progressive Alliance like the further-left New Democratic Party, Canada's Liberal Party experienced progressive inclination in the 21st century from the premiership of Justin Trudeau, who was a self-described progressive liberal. The Trudeau government's economic vision was initially based on greater tax collections to compensate for increased government spending. While the government has not balanced the budget, it has cut Canada's debt-to-GDP ratio annually until 2020, when the COVID-19 pandemic struck. Trudeau self-described his cultural policy as staunchly feminist and progressive, and his government advocated for the advancement of abortion rights, introduced the bill that made Canadian conversion therapies illegal, established the right to medically-assisted death, and legalized cannabis for recreational use. Trudeau made the announcement in 2021 that a national strategy for child care would be developed with the objective of lowering the cost of day care at a rate of ten dollars per day for each child during a period of five years. The Trudeau administration supported green politics through new pledges to reduce greenhouse gas emissions by 30% by 2030 and to achieve net-zero emissions by 2050 via a federal carbon pricing policy. Additionally, legislation for marine protection was passed by Trudeau's parliament as well as banning six common single-use plastic products and improving evaluations of environmental impact. Despite a generally green stance, Trudeau supported oil and gas pipelines to bring Canadian fossil fuel resources to foreign markets, which was met with opposition from environmental activists.

In March 2022, the NDP agreed on a confidence and supply arrangement with the Liberal Party, including policies such as establishing a national dental care program for low-income Canadians, progress toward a national pharmacare program, labor reforms for federally regulated workers, and additional taxes on financial institutions. The NDP and the Liberal Party terminated their confidence and supply agreement in September 2024. The agreement had been in place since March 2022, however it was terminated nine months ahead of schedule. On January 6, 2025, during a political crisis, Trudeau announced he would resign as Liberal leader and prime minister by 24 March 2025 upon the election of a new party leader, attributing his decision to intraparty dissent. The Liberal Party moved further from its more progressive stances toward the center under new leadership from Mark Carney, who became the first prime minister in Canadian history never to have held elected office. Carney would lead the Liberals to a minority government in late 2025 after advising the Governor General to dissolve Parliament and trigger a federal election.

United States

In the United States, both the Progressive Era and the modern movement are rooted in the notion that free markets lead to economic inequalities that can be fixed through government action and protect the working class. In the 21st century, progressives continue to favor public policy that they theorize will reduce or lessen the harmful effects of economic inequality and additionally are focused on ending systemic discrimination such as institutional racism; to advocate for social safety nets and workers' rights; and to oppose corporate influence on the democratic process. The unifying theme is to call attention to the negative impacts of current institutions or ways of doing things and to advocate for social progress, i.e., for positive change as defined by any of several standards such as the expansion of democracy, increased egalitarianism in the form of economic and social equality as well as improved well-being of a population. Proponents of social democracy have identified themselves as promoting the progressive cause. Landmark developments in progressive governance include the Consumer Financial Protection Bureau, which was originally proposed in 2007 by Elizabeth Warren, a self-described progressive capitalist who played a key role in its institutional creation. In reaction to the 2008 financial crisis and the ensuing Great Recession, the Dodd–Frank Wall Street Reform and Consumer Protection Act, which was passed in 2010, established the Consumer Financial Protection Bureau as an independent bureau within the Federal Reserve.

The Bernie Sanders 2016 presidential campaign rode a wave of left-wing populist and progressive sentiment coming out of the 2008 financial crisis and the Occupy Wall Street movement. The campaign and Sanders himself praised social democratic programs in Europe and supported workplace democracy via union democracy, worker cooperatives, and workers' management of public enterprises. This continued into his 2020 presidential campaign and the Fighting Oligarchy tour with Alexandria Ocasio Cortez, sharply critiquing neoliberal capitalism. Sanders and broader coalitions like the Congressional Progressive Caucus have called for universal, single-payer healthcare, living wage laws, reductions in military expenditure, increased corporate regulation, ending mass incarceration, and strong measures to reverse climate change. Some socialists and major socialist organizations have described Sanders as a democratic socialist, market socialist, or reformist socialist, while others have called him a reformist social democrat. Throughout the mid-2020s, progressive politics in the United States are continually moving toward left-populist economic policies, as seen in the insurgent campaigns of Zohran Mamdani (who was successfully elected the 111th mayor of New York City in 2025), and Senate candidate for Michigan Abdul El-Sayed. As a candidate and as mayor, Mamdani has called for New York City to raise the local minimum wage to $30 by 2030, implementing higher taxes on corporations and high-income earners to fund free tuition at CUNY and SUNY, universal childcare, city-owned grocery stores, and free public transit, while cutting taxes for outer-borough homeowners and reforming New York's property tax system. In the 2026 United States House of Representatives elections in New York, progressive and socialist candidates received much media attention for a successful primary night, defeating more moderate Democratic incumbents in the 10th and 13th districts and winning the open 7th in what was described as a "clean sweep" for Mayor Mamdani and the Democratic Socialists of America.

Types

Cultural progressivism

The term cultural liberalism is used in a substantially similar context and can be said to be a synonym for cultural progressivism, deriving from the concept of moral progress and viewing liberalism as central to the development of culture. Cultural progressives may be economically centrist, conservative, or progressive. For example, American libertarians, who are a prominent strain of neoclassical liberalism, are often characterized by their fiscal conservatism and cultural progressivism. The Czech Pirate Party is classified as a culturally progressive party, and it calls itself "economically centrist and socially liberal." Economist Emily Chamlee-Wright has written that cultural liberalism is one of the "Four Corners of Liberalism" (the other three being economic, epistemic, and political), describing cultural liberalism as "encourag[ing] us to experiment with different ways of living. It allows us to learn that peaceful coexistence in a pluralistic society is possible. And it helps to ensure that minority communities are considered full-fledged participants in the social order." Chamlee-Wright noted a special interchange between political liberality and cultural progressivism, pointing to Jonathan Rauch's contention that "the legalization of gay marriage would not have happened without free speech, which drove cultural progress. But that cultural progress arguably accelerated change that favored a politically liberal outcome." Civil libertarianism is considered a more radical variant of cultural liberalism or cultural progressivism.

Economic progressivism

Economic progressivism—also New Progressive Economics—is a term used to distinguish it from progressivism in cultural fields. Economic progressives may draw from a variety of economic traditions, including democratic capitalism, democratic socialism, social democracy, and social liberalism. Overall, economic progressives' views are rooted in the concept of social justice and the common good, and aim to improve the human condition through government regulation, social protections and the maintenance of public goods. Some economic progressives may show conservative views on cultural issues. These movements are related to communitarian conservative movements such as Christian democracy and one-nation conservatism.

Techno progressivism

An early mention of techno-progressivism appeared in 1999 as the removal of "all political, cultural, biological, and psychological limits to self-actualization and self-realization". According to techno-progressivism, scientific and technical aspects of progress are linked to ethical and social developments in society. Therefore, according to the majority of techno-progressive viewpoints, advancements in science and technology will not be considered proper progress until and unless they are accompanied by a fair distribution of the costs, risks, and rewards of these new capabilities. Many techno-progressive critics and supporters believe that while improved democracy, increased justice, decreased violence, and a broader culture of rights are all desirable, they are insufficient on their own to address the problems of modern technological societies unless and until they are accompanied by scientific and technological advancements that uphold and apply these ideals.
