Vilnius County (Lithuanian: Vilniaus apskritis) is the largest of the 10 counties of Lithuania, located in the east of the country around the city Vilnius. On 1 July 2010, the county administration was abolished, and since that date, Vilnius County remains as the territorial and statistical unit.
Until the Partitions of the Polish–Lithuanian Commonwealth in late 18th century the area belonged to the Vilnius Voivodship and Trakai Voivodship of the Polish-Lithuanian Commonwealth. In Russian Empire it belonged to the Northwestern Krai and approximately corresponded to its Vilna Governorate (as of 1843). During World War I, following the German offensive of 1915, it was occupied by the German army. After the war, some parts of the area was ruled by local Polish self-government established after the German Ober-Ost army withdrew from the area.
Following the start of the Polish-Bolshevik War in 1919, it was occupied by the Red Army, which was pushed back by the Polish Army. In 1920, it was again occupied by the Red Army, but Soviets officially recognized the sovereignty of Lithuanian Republic over the city immediately after defeat during Battle of Warsaw. During their retreat, the Bolsheviks passed the sovereignty over the area to Lithuania. The Polish commander Józef Piłsudski ordered his subordinate general Lucjan Żeligowski to "rebel" his Lithuanian-Belarusian division and capture the city of Vilnius, without declaring war on Lithuania. The area of the future Vilnius County was seized by the Polish forces without significant opposition from Lithuanian forces and Gen. Żeligowski created a short-lived state called Republic of Central Lithuania. Following the elections held there in 1922 the state was incorporated into Poland (see Vilnius region, Central Lithuania).
