The Concordats of Constance were five agreements between the Catholic Church and the "nations" of England (including Scotland), France, Germany (including Scandinavia and eastern Europe), Italy (Imperial Italy, the Papal States, Naples, Sicily, and the Venetian Republic)[1][2] and Spain (Aragon, Castile, Navarre and Portugal) in the aftermath of the Council of Constance (1414–18) that ended the Western Schism.
Their chief importance lies in the fact that, together with the seven reform statutes of Pope Martin V, they settled all outstanding issues and brought the papal schism to an end.
The appropriation of benefices for the use of monasteries, collegiate churches or cathedral chapters was prohibited without the approval of the local bishop.
[5] For a long time, it was thought that concordats had been signed with the Spanish and Italian nations, but that the texts had been lost.
In 1867, the German historian Bernhard Hübler argued that the French concordat applied also to Italy and Spain.
