The colors of the flag were inspired by the 1192 coat of arms of Bohemia. The chevron was added to the flag to differentiate it from the flag of Poland.
There are three colors used in the flag of the Czech Republic: white, red, and blue. The white and red are used to create the two horizontal bands of the flag. The blue chevron is located along the hoist side of the flag. These colors were chosen based on the coat of arms of Bohemia, which features a lion with a silver tail on a red field.
This flag was originally adopted by Czechoslovakia in 1920. After it was banned in the nation in the late 1930s, it was restored again in 1945.
The nation of Czechoslovakia dissolved in the 1990s and formed two new nations: Slovakia and the Czech Republic. When negotiations were ongoing, it was determined that Czechoslovakian state symbols would not be used by either nation. However, the Czech Republic passed legislation that allowed the nation to adopt this flag as its own. It was officially adopted as the flag of the Czech Republic on January 1, 1993.
The Czechoslovakia flag – which is now the flag of the Czech Republic – was banned by Nazis from 1939 to 1945.
The flag used by the Czech Republic was designed by Jaroslav Kursa.
