The flag of Ukraine is a bicolor banner of two equally sized horizontal bands of blue and golden yellow with blue being on the top. The golden yellow symbolizes fields of wheat and the blue represents peace as well as the sky, mountains, and streams of Ukraine. The combination of blue and yellow as a symbol of Ukrainian lands comes from the flag of the Kingdom of Galicia-Volhynia used in the 12th century. These colors were used prominently during the country’s fight for independence.
As a national flag, the blue and yellow bicolor has been officially used since the 1848 Spring of Nations, when it was raised over the Lviv Rathaus (City 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. 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-azure flag of the Ukrainian SSR. The blue and yellow flag was provisionally adopted for the official ceremonies in September 1991 following Ukrainian independence, before finally being officially restored and adopted on January 28, 1992 by the parliament of Ukraine.
Most of the Ukrainian flags are flown horizontally but some public buildings fly the flag vertically. When the flag is flown vertically it must be flown with the blue band on the left.
The Ukrainian flag can be decorated with golden fringe on its perimeter provided it does not deface the flag.
Ukraine has celebrated Flag Day each year on August 23rd since the year 2005. Ukraine is bordered by Russia to the east; Belarus to the north; Poland, Slovakia and Hungary to the west; and Romania and Moldova to the south.
