Mieszko II Lambert
In the end, Bolesław I took control over all the territories of his father and expelled his stepmother and half-brothers from Poland to Germany. Mieszko's further fate is unknown, but in 1032 a certain Dytryk (son of either Mieszko or his brother Lambert) returned to Poland and took control over part of the country after the fall of Mieszko II Lambert. Dytryk's reign was short-lived: in 1033, he was deposed and expelled by Mieszko II, who reunited all Poland.
