"Conrad I (c. 1097 – 5 February 1157), called the Great (German: Konrad der Große), a member of the House of Wettin, was Margrave of Meissen from 1123 and Margrave of Lusatia from 1136 until his retirement in 1156. Initially a Saxon count, he became the ruler over large Imperial estates in the Eastern March and progenitor of the Saxon electors and kings." - (en.wikipedia.org 30.01.2020)
