Through Middle Ages, Europe and Loan

From 1287 to 1355, during the rule of the Noveschi, the Republic experienced a period of great political and economic splendor: new buildings were commissioned, including that of the Cathedral of Siena, the Palazzo Pubblico, and a substantial part of the city walls completed. This government is in fact defined by historians as the "good governance".

A combination of economic decline, sparked by the Black Death, and political instability led to its absorption by the rival Duchy of Florence during the Italian War of 1551–1559. Despite resisting for 18 months, it surrendered on 21 April 1555, marking the end of the republic.

History

Origins

The foundation of the Republic of Siena is traditionally dated to 1125, the year in which the last reigning representative of the Government of Bishops was deposed, at the time at the head of the city and the surrounding countryside. A consular government was appointed to administer the state in its early term. As in most of the medieval municipal cities, Siena too had the Consuls as its first development of the judiciary. In 1125 the office of Consul Sænensis was attributed to Manco.

Growth

Siena prospered as a city-state, becoming a major centre of money lending and an important player in the wool trade. At first it was governed directly by its bishop, but episcopal power declined during the 12th century. The bishop was forced to concede a greater say in the running of the city to the nobility in exchange for their help during a territorial dispute with Arezzo, and this started a process which culminated in 1167 when the commune of Siena declared its independence from episcopal control. By 1179, it had a written constitution.

In 1286 the Nove ("the Nine") government was established to rule Siena. The Nove was backed by the Noveschi, a political party formed by the merchant families that sat on the council. Eventually, the Noveschi party grew to include not only members of the Nove council, but also many prominent noble families of the city. Under the guide of the Nove and the Noveschi, Siena grew in both economic and military dominance.

The Battle of Montaperti

In the 13th century, Siena was predominantly Ghibelline, in opposition to Florence's Guelph position (this conflict formed the backdrop for some of Dante Alighieri's Divine Comedy, completed in 1320).

On 4 September 1260 the Sienese Ghibellines, supported by the forces of King Manfred of Sicily, defeated the Florentine Guelphs in the Battle of Montaperti. Before the battle, the Sienese army of around 20,000 faced a much larger Florentine army of around 33,000. Prior to the battle, the entire city was dedicated to the Virgin Mary (this was done several times in the city's history, most recently in 1944 to guard the city from Allied bombs). The man given command of Siena for the duration of the war, Bonaguida Lucari, walked barefoot and bareheaded, a halter around his neck, to Siena Cathedral. Leading a procession composed of all the city's residents, he was met by all the clergy. Lucari and the bishop embraced to show the unity of church and state, then Lucari formally gave the city and contrade to the Virgin. Legend has it that a thick white cloud descended on the battlefield, giving the Sienese cover and aiding their attack. The reality was that the Florentine army launched several fruitless attacks against the Sienese army during the day, then when the Sienese army countered with their own offensive, traitors within the Florentine army killed the standard bearer and in the resulting chaos, the Florentine army broke up and fled the battlefield. Almost half the Florentine army (some 15,000 men) were killed as a result.

The period 1260–1355 has been characterized as a "golden age" in Siena.

Ports of the Republic of Siena

The Republic of Siena in its progressive territorial growth saw its borders expanding especially in the territories of southern Tuscany in the current province of Grosseto. The possession of an "access to the sea" by Siena was therefore a natural continuation of its expansionary and commercial policy in the Maremma with the conquest of the ports of Talamone, Porto Ercole and Porto Santo Stefano.

In order to ensure access to maritime traffic and a competitive sales network, Siena already tried to secure the use of the Grosseto river port in the 13th century. However, the port, swept away during the 14th century by the violent flood that removed the course of the Ombrone from the city, never had any development, also due to the incorrect economic policy of Siena and the lack of a productive background.

Decline

Siena was devastated by the Black Death of 1348, and also suffered from ill-fated financial enterprises. In 1355, with the arrival of Charles IV of Luxembourg in the city, the population rose and suppressed the government of the Nove council and expelled any family associated with the Noveschi party. They established a Dodici government (council of 12 nobles), assisted by another council with a popular majority. This form of government was short-lived, soon replaced by the Quindici ("The Fifteen") reformers in 1385, the Dieci ("The Ten", 1386–1387), Undici ("The Eleven", 1388–1398) and the Twelve Priors (1398–1399) who, in the end, gave the city's lordship to Gian Galeazzo Visconti, the Duke of Milan, in order to defend it from Florentine expansionism.

Five years later, the House of Visconti was expelled in 1404, and a new government of Ten Priors was established, this time in alliance with Florence against King Ladislaus of Naples. With the election of the Sienese Enea Silvio Piccolomini of the prominent Piccolomini noble family as Pope Pius II in 1458, the nobles who had been expelled due to association with the Noveschi party were allowed to return to the city.

In 1472 the Siena magistrates founded a "mount of piety", the Banca Monte dei Paschi di Siena, which would survive into the 21st century as "the world's oldest bank".

Petrucci era

The Noveschi returned to the city under Pandolfo Petrucci in 1487. Pandolfo slowly gathered many political offices and grew his influence until 1500, when with the execution of his father-in-law Niccolò Borghese for conspiracy to murder him, as well as with the support of Florence and of Alfonso of Calabria, Pandolfo was able to seize complete control of the city. Though an autocrat, Pandolfo brought Siena back to prosperity, favoring arts and sciences, as well as improving its economy. Pandolfo was succeeded by his son Borghese Petrucci. After only 4 years of rule, Borghese was ousted by his cousin, cardinal Raffaello Petrucci, helped by Pope Leo X. In the wake of more responsibilities from the Church, Raffaello was forced to cede the city to his nephew, Francesco Petrucci, who only ruled for a year before being ousted by Pandolfo's youngest son, Fabio. Fabio was exiled in 1525 by the Sienese people, marking the end of the Petrucci era.

End of the Republic

With the end of the Petrucci era internal strife resumed, with the popular faction ousting the Noveschi party supported by Pope Clement VII: the latter sent an army, but was defeated at Camollia in 1526. Emperor Charles V took advantage of the chaotic situation to put a Spanish garrison in Siena. From 1529 until 1541 the republic was governed by Alfonso Piccolomini. The citizens expelled him in 1552, allying with France: this was unacceptable for Charles, who sent his general Gian Giacomo Medici to lay siege to it with a Florentine-Imperial army.

The Sienese government entrusted its defence to Piero Strozzi. When the latter was defeated at the Battle of Marciano in August 1554, any hope of relief was lost. After 18 months of resistance, Siena surrendered to Spain on 21 April 1555, marking the end of the Republic. The new Spanish King Philip II, owing huge sums to the House of Medici, ceded Siena's entire territory to the Duchy of Florence (apart from a series of coastal fortress annexed to the State of the Presidi), with which it was merged in 1569 to form the Grand Duchy of Tuscany. An exiled Sienese republican government of 700 Sienese families in Montalcino did not concede defeat in the Battle of Marciano and continued to resist Tuscan rule until 1559, when Tuscan troops arrived and annexed Montalcino, too.
