King Wladyslaw I (New Poland)

Background
Wladyslaw I of Poland (1042-1110), also referred to as King Wladyslaw I of Poland, was the second son of Casimir I the Restorer and Maria Dobroneiga. He was ruler of Poland from 1079 AD and was variously referred to as  'Dux Wladyslaw I', 'King Wladyslaw I' and on later documentation 'Emperor Wladyslaw I of New Poland' although the last is generally considered erroneous. He is credited with the foundation of the nation of New Poland.
