The Treaty of Leipzig or Partition of Leipzig (German Leipziger Teilung) was signed on 11 November 1485 between Elector Ernest of Saxony and his younger brother Albert III, the sons of Elector Frederick II of Saxony from the House of Wettin. The agreement perpetuated the division of the Wettin lands into a Saxon and a Thuringian part, which in the long run obstructed the further development of a Central German hegemonic power in favour of Brandenburg-Prussia.
