The pan-Slavic colors—blue, white and red—were defined by the Prague Slavic Congress, 1848, based on the symbolism of the colors of the flag of Russia, which was introduced in the late 17th century. Historically, however, many Slavic nations and states had already adopted flags and other national symbols that used some combination of those three colors. Slavic countries that use or have used the colors include Russia, Yugoslavia, The flag of the Czech Republic adopted its three national colors in 1920 with the founding of Czechoslovakia.
