The Flag of Ukraine (Ukrainian: Прапор України, romanized: Prapor Ukrainy) consists of equally sized horizontal bands of blue and yellow. As a national flag, the blue and yellow bicolour has been used since the 1848 Spring of Nations, when it was hoisted over Lviv Town Hall. It was officially adopted as a state flag for the first time in 1918 by the short-lived West Ukrainian People's Republic and subsequently used by the Ukrainian People's Republic, just before World War II it was also adopted by Carpatho-Ukraine in March 1939.
