Afonso Henriques’ Galician Campaign and the Trial…

Afonso Henriques’ Galician Campaign and the Trial at Valdevez (1140)

Seeking to assert his mother’s rightful claims to lands in Galicia, Afonso Henriques pressed northward, provoking his cousin, King Alfonso VII of León and Castile, to raise an army and invade Portuguese territory in 1140. Rather than engaging in open warfare, the two rulers agreed to settle their dispute through a chivalric trial by combat at Valdevez.

The Trial at Valdevez and Portuguese Victory

In this grand tourney, Portuguese and Leonese knights clashed in a mock battle, where the Portuguese forces emerged victorious. As a result, the disputed Galician lands came under Portuguese control, and Alfonso VII, though reluctant, acknowledged Afonso Henriques’ authority over Portugal.

Towards Formal Recognition: The Peace of Zamora (1143)

Although this encounter effectively confirmed Portugal’s de facto independence, it was not until 1143, at the Peace of Zamora, that Alfonso VII formally recognized Afonso Henriques as King of Portugal, laying the foundation for the kingdom’s full sovereignty.
