The legend of the three brothers Lech, Cech, and Rus, who became the ancestors of the Polish, Czech, and Rus, explains how these cultures were created. The legend involves the brothers being the son of prince Pan and leaving the Pannonia empire. Some accounts don’t involve Rus, rather just Lech and Cech, who are the sons of Jan and not Pan.
The Czech Flag: A Century of Waving
Inspired by the American holiday, many nations in the world celebrate Flag Day, including Czechia. Before Czechia, there was Czechoslovakia, whose flag, created in 1918, featured 2 horizontal stripes, white on the top and red on the bottom. The flag changed to include a blue wedge from the left and has remained this way since, including after the separation of Czechoslovakia into the Czech Republic and Slovakia.
