Flag of Ukraine - Прапор України

The state flag of Ukraine (Ukrainian: державний прапор України; translit.: derzhavnyy prapor Ukrayiny; literally 'state flag of Ukraine') is a banner of two equally sized horizontal bands of blue and yellow colour, which symbolise the clear blue sky over yellow wheat field. (Constitution of Ukraine, Article 20) As a national flag, the blue and yellow bicolour was officially used since the 1848 Spring of Nations when it was hoisted over the Lviv Rathaus. It is was officially adopted as a state flag for the first time in 1918 by the short-lived Ukrainian People's Republic. When Ukraine was part of the Soviet Union, the flag was outlawed and before 1949 there was no official state flag until adoption of the red-blue flag of the Ukrainian SSR. People who were hoisting the blue-yellow flags in the Soviet Ukraine were prosecuted as criminals. The blue and yellow flag was provisionally adopted for official ceremonies in September 1991 following Ukrainian independence, before finally officially being restored in 1992.
