Battle of São Mamede

Common card · No. 446234

The Battle of São Mamede (Portuguese: Batalha de São Mamede) took place on 24 June 1128 near Guimarães and is considered an important event in the process that led to the establishment of Portugal as an independent kingdom. Forces led by Afonso Henriques defeated forces led by his mother, Theresa of Portugal, and Fernão Peres de Trava. Though he took control of the County of Portugal, he remained a vassal of King Alfonso VII of León and Castile, who was nominally the overlord of the county. Following the battle, Afonso Henriques consolidated his control over the County of Portugal. He later adopted the title of King of Portugal, following his victory at the Battle of Ourique in 1139, and his royal title was recognized by Alfonso VII of León and Castile in the Treaty of Zamora in 1143.
