Treaty of Leipzig
The Treaty of Leipzig or Partition of Leipzig (German: Leipziger Teilung) was signed on 11 November 1485 in the city of Leipzig, between Ernest, Elector of Saxony and his younger brother Albert III, the sons and heirs of Frederick II, Elector of Saxony (d. 1464) from the House of Wettin. The treaty ended the period of joint rule by two brothers, that lasted from 1464 to 1485. Under the Leipzig treaty provisions, Ernest kept the Saxon electoral title (attached to the Duchy of Saxe-Wittenberg) and several domains in southern parts of Thuringia, while Albert received the Saxon ducal title and rule over the old Margraviate of Meissen, together with various domains in northern parts of Thuringia. The Leipzig treaty and its arrangements perpetuated the division of Wettin lands in two distinctive domains, administered separately, by rulers from Ernestine and Albertine branches of the dynasty.
