Afonso I[a] (Portuguese pronunciation:[ɐˈfõsu]; 1106/1109/1111 – 1185), also called Afonso Henriques, nicknamed the Conqueror (Portuguese: O Conquistador) and the Founder (Portuguese: O Fundador)[2][3] by the Portuguese, was the first king of Portugal. He achieved the independence of the County of Portugal, establishing a new kingdom and doubling its area with the Reconquista, an objective that he pursued until his death.
Afonso was the son of Theresa of León and Henry of Burgundy, rulers of the County of Portugal. Henry died in 1112, leaving Teresa to rule alone. Unhappy with Teresa's romantic relationship with Galician Fernando Pérez de Traba and his political influence, the Portuguese nobility rallied around Afonso, who revolted and defeated his mother at the Battle of São Mamede in 1128 and became Count of Portugal soon afterwards. In 1139, Afonso renounced the suzerainty of the Kingdom of León and established the independent Kingdom of Portugal.
Afonso actively campaigned against the Moors in the south. In 1139 he won a decisive victory at the Battle of Ourique, and in 1147 he conquered Santarém and Lisbon from the Moors, with help from men on their way to the Holy Land for the Second Crusade. He secured the independence of Portugal following a victory over León at Valdevez and received papal approval through Manifestis Probatum. Afonso died in 1185 and was succeeded by his son, Sancho I.
