Alcáçovas marks 547 years since the Treaty of Alcáçovas

The town of Alcáçovas marks the 547th anniversary of the signing of the Treaty of Alcáçovas-Toledo. Signed on September 4, 1479, at the Paço dos Henriques, the agreement between the kingdoms of Portugal and Castile ended the War of the Castilian Succession.

This landmark diplomatic accord established spheres of influence for maritime expansion. Under the treaty, Castile retained control of the Canary Islands, while Portugal secured dominance over Madeira, the Azores, Cape Verde, and the coast of Guinea. The agreement utilized an imaginary line at the 27th parallel to define maritime control, serving as a precursor to the later Treaty of Tordesillas.

The Paço dos Henriques, which hosted the negotiations, has been restored and currently serves as a tourism office and a branch of the Municipal Library.
