Henry I, Prince of Anhalt

Henry I (c. 1170–1252), of the House of Ascania, was Count of Anhalt from 1212 and its first ruling prince from 1218. On his father Bernhard's death in 1212 he received the old Ascanian lands in the Schwabengau, while his brother Albert took the Saxon ducal title. He styled himself prince from about 1215 and was raised to princely rank by Emperor Frederick II.

He backed Frederick against the rebel King Henry (VII) in 1234. Around 1245 he retired and divided Anhalt among his sons Henry II, Bernhard and Siegfried.
