Lech, Čech, and Rus is a legend of three brothers – Lech, Čech, and Rus – who founded three Slavic nations: Poland (also known as Lechia), Bohemia (Čechy, now known as the Czech Republic), and Ruthenia (Rus', whose successor states are now Russia, Belarus and Ukraine). There are multiple versions of the legend, including several regional variants that mention only one or two of the brothers.
