The blue and yellow bicolour first appeared during the 1848 Spring of Nations in Lemberg, then part of the Austrian Empire. It was adopted as a state flag for the first time in the aftermath of the Russian Revolution by the Ukrainian People's Republic, the West Ukrainian People's Republic and the Ukrainian State. It was also later adopted by Carpatho-Ukraine in March 1939. When Ukraine was part of the Soviet Union, the bicolour was banned and it used the flag of the Ukrainian Soviet Socialist Republic which featured a red flag along with the azure bottom with a golden hammer and sickle and a golden-bordered red star on top. During the dissolution of the Soviet Union, the bicolour gradually returned in use before officially being adopted again on 28 January 1992 by the Ukrainian parliament.
Ukraine has celebrated the Day of the National Flag on 23 August since 2004.
