The Legend of Lech, Czech and Rus is one of the most important Polish legends telling the story of relations between different Slavic peoples, the origins of the Polish state and the origin of the Polish national colours, emblem and the first capital of Poland. The protagonists of the story are three brothers, Slavic princes, who set out from the territories of ancient Croatia to the north and travel through uninhabited areas with their people in search of a new place to settle. Rus was the first to break away from the common wandering, announcing to his brothers that his people did not have the strength to travel further and had to end the journey and establish a settlement. Then Bohemia, who settled near the mountains, separated from further wandering. Finally, Lech too found a place for himself - on a plain by the water. When Lech and his people heard a yell and saw a white eagle perched in its nest on a great Oak tree on a hill, against the backdrop of a red sunset, they decided that this was a sign from God that they had chosen a good place to build a castle. According to legend, this is where the name of today's city of Gniezno, the first capital of Poland, and its coat of arms, a white eagle on a red background, came from. The legend was first written down in the so-called Polish-Hungarian Chronicle, which historians date to 1222. According to this chronicle, the three brothers first launched the Great Moravian State and then three separate states: Poland, Bohemia (Czechia) and Ruthenia.
