History of Portugal since the Battle of Aljubarrota
Also known as
Batalha de Aljubarrota; Сражение при Алжубарроте

When King Ferdinand I died in 1383, his only daughter Beatrice was the wife of John I of Castile, and Portugal faced absorption by its neighbour. Lisbon and much of the country backed John, Master of the Order of Aviz and an illegitimate son of Peter I; in April 1385 the Cortes of Coimbra acclaimed him king, and Castile invaded.

Nuno Álvares Pereira chose a defensive position on a small plateau at São Jorge, protected by streams, ditches and pits. Late in the afternoon of 14 August the French heavy cavalry allied with Castile charged uphill and was destroyed by arrows and dismounted men-at-arms; the main Castilian army broke and fled within about an hour. In thanks for the victory John I founded the Monastery of Santa Maria da Vitória at Batalha. Castile recognised the new dynasty only in the Treaty of Ayllón of 1411.
