Medieval period and
Boyan Based on excavations at the end of the 20th century, information was found on the birth of the city in the 10th century on the Chashin Kurgan. For ease of perception, the conventional date of birth was chosen as 985 AD. The first written mention of Bryansk, as
Debryansk, dates to 1146 in the
Kievan Chronicle. The name appears variously as , and in other spellings. Etymologically, it derives from "дъбръ", a Slavic word for "ditch", "lowland", or "dense woodland"; the area was known for its dense woods, of which very little remains today. Local authorities and archaeologists, however, believe that the town had existed as early as 985 as a fortified settlement on the right bank of the
Desna River. Bryansk remained poorly attested until the 1237–1242
Mongol invasion of Kievan Rus'. It was the northernmost of the
Severian cities in the possession of the
Olgovichi clan of
Chernigov. After the Mongols executed Prince
Mikhail of Chernigov in 1246 and his capital was destroyed, his purported son
Roman Mikhailovich moved his seat to Bryansk. In 1310, when the Mongols sacked the town again, it belonged to the
Principality of Smolensk. Grand Duke
Algirdas of
Lithuania acquired Bryansk through inheritance in 1356 and gave it to his son,
Dmitry the Elder. Until the end of the century Grand Duke
Jogaila of Lithuania, Grand Duke
Vytautas of Lithuania, the future Grand Duke
Švitrigaila of Lithuania, and Grand Duke
Yury of Smolensk contested control of the town.
Modern period The
Grand Duchy of Moscow conquered Bryansk following the
Battle of Vedrosha in 1503. The town was turned into a fortress which played a major role during the
Time of Troubles (1598–1613). During the Time of Troubles the
Polish–Lithuanian Commonwealth occupied the town in 1610, and it remained in Polish-Lithuanian hands as part of
Smolensk Voivodeship until the
Truce of Deulino in 1634. In 1709 Tsar
Peter the Great incorporated Bryansk into the
Kiev Governorate, but Empress
Catherine the Great deemed it wise to transfer the town to the newly-formed
Oryol Governorate in 1779. She also promulgated the town's coat of arms (August 1781). In the 17th and 18th centuries the economy of Bryansk, which had become a regional trading center, was based on the Svenskaya fair (), the largest in
European Russia. The fair took place annually under the auspices of the nearby
Svensky Monastery. After the town started to manufacture cannon and ammunition for the
Imperial Russian Navy in 1783, Bryansk evolved from a regional market town into an important industrial center for
metallurgy and
textiles. The city's population exceeded 30,000 by 1917. In 1812
Napoleon's
Grande Armée fought the Russians in Bryansk and in
Oryol during the
French invasion of Russia. at former Christmas Mountain (now
Yuri Gagarin Boulevard) in 1920 In 1918 the
Belarusian People's Republic and
Ukrainian People’s Republic both claimed Bryansk, but
Bolshevik forces took the town in 1919. During
World War II the German
Wehrmacht captured Bryansk and encircled the Soviet
3rd,
13th and
50th armies. The town remained under
Axis occupation from October 6, 1941 to September 17, 1943, with the city left heavily damaged by fighting. The occupiers operated a Nazi prison in the city. About 60,000
Soviet partisans were active in and around Bryansk, inflicting heavy losses on the German Army. In 1944, soon after
its liberation, Bryansk became the administrative center of
Bryansk Oblast.
Recent history In 2016 the city council approved a new general city plan, which called among others for laying of a new route from Burov Street along the Bolva River to Vokzalnaya Street with the intersection of the railway and Bolva. In the southern direction, it is proposed to extend the road along the Desna to the Fokinsky District to Moskovsky Prospekt, construction of a road from the Black Bridge along the Karachizh ravine with the intersection of Stanke Dimitrova Avenue to Sakharova Street, reconstruction of Sakharova Street to the bypass road and the R120 highway, as well as development of the area of the old airport (area of Gorbatova, Stepnaya streets). A large fire was noted at an oil depot on April 25, 2022. Speculation was that it might have been a result of military action during the
2022 Russian invasion of Ukraine. In the
Bryansk school shooting on December 7, 2023, a 14-year-old girl took a shotgun to her school and fired several shots at schoolmates. She killed one and wounded five before killing herself. On 10 March 2026, multiple
Storm Shadow missiles struck the
Kremniy El factory in Bryansk, a large producer of military microelectronics. The strike caused multiple large explosions and a major fire, with video showing thick black smoke over the city. Russian regional authorities reported that 8 were killed and 47 injured. ==Demographics==
