Thietmar, Prince-Bishop of Merseburg from 1009 until his death in 1018, was an important chronicler recording the reigns of German kings and Holy Roman Emperors of the Ottonian (Saxon) dynasty. Two of Thietmar's great-grandfathers, both referred to as Liuthar, were the Saxon nobles Lothar II, Count of Stade, and Lothar I, Count of Walbeck. They were both killed fighting the Slavs at the Battle of Lenzen.

The Bishopric of Merseburg was an episcopal see on the eastern border of the medieval Duchy of Saxony with its centre in Merseburg, where Merseburg Cathedral was constructed. The see was founded in 967 by Emperor Otto I at the same time in the same manner as those of Meissen and Zeitz, all suffragan dioceses of the Archbishopric of Magdeburg as part of a plan to bind the adjacent Slavic ("Wendish") lands in the Saxon Eastern March beyond the Saale River more closely to the Holy Roman Empire.
