Czech Republic

About the flag

It’s the Czech Republic. The flag pairs Bohemia’s historic white and red with a distinctive blue triangle at the hoist—first adopted for Czechoslovakia in 1920 and retained by the Czech Republic after the 1993 split. That blue wedge sets it apart from Poland’s simple white-over-red and Russia’s horizontal white-blue-red stripes; Bosnia and Herzegovina uses yellow and stars. The colors are Pan-Slavic: white and red from the Bohemian coat of arms, with blue symbolizing the other Czech lands (Moravia and Silesia). Memory tip: think “C for Czech = a blue Corner” pushing into the flag. If you spot white and red with a bold blue triangle on the left, you’ve found the Czech Republic.
