Kaunas is the second-largest city in Lithuania after Vilnius and an important centre of Lithuanian economic, academic, and cultural life. Kaunas was the largest city and the centre of a county in the Duchy of Trakai of the Grand Duchy of Lithuania and Trakai Palatinate since 1413. In the Russian Empire, it was the capital of the Kaunas Governorate from 1843 to 1915.
During the interwar period, it served as the temporary capital of Lithuania, when Vilnius was seized and controlled by Poland between 1920 and 1939. During that period Kaunas was celebrated for its rich cultural and academic life, fashion, construction of countless Art Deco and Lithuanian National Romanticism architectural-style buildings as well as popular furniture, the interior design of the time, and a widespread café culture.
