<P> 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 almost identical to the flag of Poland ( only the proportion was different ) , 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 . </P>
