Smolensk

First mentioned in 863, it is one of the oldest cities in Russia. It has been a regional capital for most of the past millennium, beginning as the capital of the Principality of Smolensk in the 11th-15th centuries, then the Smolensk Voivodeship of Lithuania and the Polish–Lithuanian Commonwealth, and Smolensk Governorate and Oblast within Russia. It was the main stronghold of the Smolensk Gate, a geostrategically significant pass between the Daugava and Dnieper rivers, and as such was an important point of contention in the struggle for dominance in Eastern Europe, passing at various times between Lithuania, Poland and Russia. In more recent history, it was the site of two battles in 1812 and 1941 during the French invasion of Russia and Operation Barbarossa respectively on their paths towards Moscow. The Smolensk air disaster occurred near the city in 2010.
