Characteristics of the ruler: Bolesław Chrobry was born in 966 or 967, the eldest son of Mieszko I and Dobrawa. At the beginning of his reign, he took care of the Prague bishop of Prague, Wojciech, who was expelled from Bohemia. He took advantage of his martyrdom at the hands of pagan people and his imminent canonization politically. In 1000, at a meeting in Gniezno at the tomb of Saint Adalbert with Emperor Otto III, he gained full power over the newly created church province with a center in Gniezno and was symbolically crowned. The actual coronation took place only in 1025. An attempt to conquer the Czech in 1003 caused a conflict with Germany, which ended in 1018 with the peace in Bautzen. In the same year, Chrobry undertook a victorious expedition to Kiev. He died in 1025 and was buried in the basement of the Poznań cathedral.
