Vasario 16-oji – Lietuvos valstybės atkūrimo diena
During World War I, the Council of Lithuania (Lietuvos Taryba) declared the independence of Lithuania on 16 February 1918, and the re-establishment of the Lithuanian State. Lithuania's foreign policy was dominated by territorial disputes with Poland and Germany. The Vilnius Region, and Vilnius, the historical capital of Lithuania, (and so designated in the Constitution of Lithuania) were seized by the Polish army during Żeligowski's Mutiny in October 1920 and annexed two years later by Poland. For 19 years Kaunas became the Temporary capital of Lithuania. The Polish occupation of Vilnius was greatly resented by Lithuania; there were no diplomatic relations between the two states for most of the period between the two world wars.
