Through Textile industry, Nazi Germany and World War II

The city of Sumy was founded in the 1650s by Cossacks within the historical region of Sloboda Ukraine. The city experienced rapid development starting from the second half of the 19th century and became a centre of sugar, machine building, metalworking, and textile industry, as well as an important trade fair location. Today, Sumy is one of the chief industrial and cultural centres in Northern Ukraine.

History

Sumy was founded by the Cossack Herasym Kondratyev from Stavyshche, Bila Tserkva Regiment on the banks of the Psel River, a tributary of the Dnieper. Whether it was founded in 1652 or 1655 remains a subject of discussion. In 1656–1658, at the site of the early Sumy settlement, under the leadership of the Muscovite voivode K. Arsenyev, a city fort was built, consisting of a fort and a grad (town).

In the 1670s, Sumy was expanded with the addition of a fortified posad (craftsman town), after which it became the biggest fortress in Sloboda Ukraine. From 1658 onwards, Sumy was the center of the Sumy Cossack Regiment (military unit and local administrative division). In the 1680s, unfortified suburbs began to develop around the city.

At the end of the 17th century, Sumy played a role as a collection point for Muscovite troops during the Crimean campaigns of 1687 and 1689. During the Great Northern War, from December 1708 to January 1709, the city was the stavka (headquarters) of the Muscovite Chief of Commander headed by Tsar Peter the Great. Established under the leadership of Prince A. Shakhovskoy, the commission on streamlining the Sloboda Cossack regiments was located in 1734–1743 in Sumy. From its establishment and until the liquidation of Cossackdom in Sloboda Ukraine in 1765, the Cossack officer family of Kondratyevs exercised great influence over the city.

Following the liquidation of the Cossack community in 1765, the Sumy Cossack Regiment as an administrative division was turned into Sumy Province of the newly created Sloboda Ukraine Governorate and the city of Sumy became its center. In 1780, Sumy was turned into a centre of Sumy uyezd. In 1786–1789, the city was reformed by removing its city walls.

After a period of stagnation (1765–1860s), Sumy began to transform into a big industrial and trade center with Paul's Sugar-Refining Factory (est. 1869 by I. Kharytonenko) and the Sumy Engineering Workshops (est. 1896, producing equipment for sugar refineries). With the construction of a railroad Vorozhba – Merefa, the Sumy train station was built in the city in January 1877. Various families of philanthropist industrialists, the most famous of which were the Kharytonenkos, contributed greatly to the development of Sumy.

During the Russian Revolution of 1905, Sumy was one of several areas which became famous throughout Russia for having established an independent peasant republic. The Sumy Republic was established by a peasant union.

World War II

During the German occupation of Ukraine during World War II (1941–1944), Sumy sustained heavy damage and was occupied from 10 October 1941 to 2 September 1943. In February 1942, some 1,000 Jews were murdered in Sumy in two large-scale operations. In May–June that year, the Germans and their Hungarian allies killed an additional several dozen Jews, along with thirty Roma. Some 250 Hungarian Jews were also murdered in Sumy during the occupation period. The Germans operated a Nazi prison, a forced labour battalion for Jews and Stalag 308 prisoner-of-war camp in the city.

In January 1944, the 1st Reserve Infantry Regiment of the 1st Corps of the Polish Armed Forces was stationed in Sumy, and soon the Main Formation Staff of the First Polish Army was established in Sumy. In 1944, about 30,000 Polish soldiers were stationed and underwent military training in Sumy before rejoining the fight against Nazi Germany.

After the war, the destroyed parts of the city were rebuilt.

Slobozhanshchyna (UPR)

Slobozhanshchyna was a zemlia of the Ukrainian People's Republic centered in Sumy. Founded on 6 May 1918 according to the Law "On the administrative-territorial division of Ukraine" approved by the Central Council of Ukraine, it was disbanded on 29 April 1918 by Hetman of Ukraine Pavlo Skoropadsky, who brought back old governorate divisions of the Russian Empire.

The administrative unit included Sumy, Lebedyn, Sudzha, Hraivoron, parts of Okhtyrka and Bohodukhiv povits of Kursk and Kharkov governorates.

Russian invasion

On 24 February 2022, the first day of the Russian invasion of Ukraine, Sumy came under attack by Russian forces.

On 4 April 2022, Governor of Sumy Oblast Dmytro Zhyvytskyi stated that Russian troops no longer occupied any towns or villages in Sumy Oblast and had mostly withdrawn, while Ukrainian troops were working to push out the remaining units. On 8 April, Governor Zhyvytskyi stated that all Russian troops had left Sumy Oblast, while adding that the territory of the region was still unsafe due to rigged explosives and other ammunition left behind by Russian troops. On 19 February 2025, Russia launched the Sumy Incursion against the city in hopes of capturing it but the Russian offensive stalled after four months and since then the offensive is inconclusive as of 26 June 2025, as Russian forces captured a bunch of small towns but failed to capture the city of Sumy itself. On 13 April 2025, Russia launched a missile strike against Sumy that killed at least 36 people. On 3 June 2025, Russia shelled the city, and there were reports of many thousands of Russian troops massing in the area.
