After the Third Partition of the Polish-Lithuanian Commonwealth in 15 April 1795, Vilnius was annexed by Russian Empire and became the capital of a Vilna Governorate. During the Russian occupation the city walls were destroyed, and by 1805, only the Dawn Gate remained. In 1812, the city was seized by Napoleon on his push towards Moscow. Following the November Uprising in 1831, Vilnius University was closed and Russian repressions damaged the development of the city. During the January Uprising in 1863 heavy fighting occurred within the city, but was brutally pacified by Mikhail Muravyov, by the population because of the number of executions he organized. After the uprising, all civil liberties were withdrawn, and use of the Polish and Lithuanian languages was banned. in early 20th century Lithuanian speaking population constituted only a small minority then, with Polish, Yiddish, and Russian speakers being most of the population of the city.
