Bolesław IV the Curly
In 1173, Mieszko III succeeded his older brother Bolesław IV the Curly as High Duke of Poland and Eudoxia served as his High Duchess consort. However, their reign was short-lived: in 1177 Mieszko III's eldest son Odon rebelled against him, with the help of his uncle Casimir II the Just. The main reason of Odon's rebellion was the favoritism showed by Mieszko III to his children with Eudoxia, and the attempts of the High Duke to force him to become a priest, in order to eliminated from the succession.
