Concordat of Vienna concluded

Timeline

1. 1439–1447Holy Roman Empire · Holy Roman EmpireSome imperial princes had supported the Council of Basel and the antipope. After Eugene IV deposed the Elector-Archbishops of Trier and Mainz, the two sides reached the Electors' Concordat in January 1447: the papacy restored the two to their posts, and the electors recognized Eugene as the legitimate pope. After Nicholas V succeeded him, a long-term arrangement covering the entire imperial church was needed.
2. 1448Vienna · ViennaFrederick III and the papal legate Cardinal Juan de Carvajal signed in Vienna on 17 February. The terms provided that the initial election of bishops would in principle be free of papal intervention, but the pope retained the right to confirm the elected and to remove those he deemed unfit. Nicholas V approved on 19 March, and the curia clearly held the upper hand in final personnel decisions.
3. 1448–1449Holy Roman Empire and Rome · Holy Roman EmpireThe concordat was judged a complete victory for the papacy over the reform party, giving the pope stronger control over the German church than over several other regions. The empire thereafter withdrew its substantive support for the Basel antipope, and the conciliar movement waned with the close of Basel in 1449. This framework regulated imperial-papal relations until the empire's dissolution in 1806.
