The national flag of the Czech Republic (Czech: státní vlajka České republiky) is the same as the flag of the former Czechoslovakia. Upon the dissolution of Czechoslovakia, the Czech Republic kept the Czechoslovak flag while Slovakia adopted its own flag. The first flag of Czechoslovakia was based on the flag of Bohemia, and was white over red. This was identical to the flag of Poland, so a blue triangle was added at the hoist in 1920. The flag was banned by the Nazis in 1939, and a horizontal tricolor of white, red, and blue was enforced. The 1920 flag was restored in 1945.
