Eric II
In 1459, Frederick III, Holy Roman Emperor, renounced all freedoms previously granted by the emperors to the Pomeranian dukes. The same year, Eric of Pomerania's death caused a conflict between the remaining dukes Eric II, Wartislaw X and Otto III about Eric's heritage – Eric II claimed all for himself. This led Otto III and Wartislaw X to ally with the elector of Brandenburg on 6 September 1459, and with Denmark on 27 July 1462, both alliances were directed against Eric II. The dukes however reconciled in 1463.
