Flag of Czechia
Colors

Meaning & Symbolism
White and red are the traditional colors of Bohemia. The blue triangle was added in 1920 to differentiate from Poland and represent Slovakia and Moravia.
History
Czechoslovakia used this design since 1920. After the 1993 separation, Slovakia created a new flag and Czechia kept the original, although this violated the division agreement.
Curiosities
Technically Czechia should not use this flag according to the agreement with Slovakia, but does so anyway. It is the only flag "inherited" from a dissolved federation.
