The Lithuanian flag was raised for the first time on January 1, 1919 in Vilnius by a small group of volunteers who were part of the Lithuanian military formations. In memory of this event, every year on the first day of the new year, Lithuania celebrates the Lithuanian Flag Day (Lithuania Lietuvos Vėliavos diena).
From the end of the 15th century and for more than four centuries, the flag of Lithuania was red, and a white knight was depicted on the flag. In 1918, just such a flag became the state flag of Lithuania.
The Lithuanian Council established a special commission to design the national flag, and on April 19, 1918, a horizontal tricolor was adopted using the colors most popular in traditional Lithuanian clothing.
