Frederick II, Elector of Saxony

Frederick II, The Gentle was Prince-Elector and Arch-Marshal of the Holy Roman Empire, who ruled as Duke of Saxony and Margrave of Meissen (1428–1464) and Landgrave of Thuringia (1440–1445). His succession laid the basis for the later division of the House of Wettin, as his two sons, Ernest and Albert, inherited his territories jointly, before eventually forming the Ernestine and Albertine branches, through the Treaty of Leipzig (1485).
