>>21527952In the Polish version of the legend, three brothers went hunting together but each of them followed a different prey and eventually they all traveled in different directions. Rus went to the east, Čech headed to the west to settle on the Říp Mountain rising up from the Bohemian hilly countryside, while Lech traveled north. Lech, while hunting, followed his arrow and suddenly found himself face-to-face with a fierce, white eagle guarding its nest from intruders. Seeing the eagle against the red of the setting sun, Lech took this as a good omen and decided to settle there. He named his settlement Gniezno (Polish: gniazdo – 'nest') in commemoration and adopted the White Eagle as his coat-of-arms. The white eagle remains a symbol of Poland to this day, and the colors of the eagle and the setting sun are depicted in Poland's coat of arms, as well as its flag, with a white stripe on top for the eagle, and a red stripe on the bottom for the sunset. Lech founded the Polish Kingdom at the beginning of fifth century.
According to Wielkopolska Chronicle (13th century), Slavs are descendants of Pan, a Pannonian prince. He had three sons – Lech (the youngest), Rus, and Čech (the oldest), who decided to settle north, east, and west, respectively.
