When the Saxon duchy was partitioned between two branches of the House of Askanien the northern part
became
the duchy of Sachsen-Lauenburg. An additional partition occurred 1305, but Sachen-Lauenburg was reunited a hundred years later. Throughout its
existence it was an insignificant principality in Northern Germany. When
the house of Askanien died out 1689 the duchy was granted to the duke of L�neburg-Celle, whose lands were inherited by the elector of Hanover 1705.
