Afonso I of Portugal (b. 1109)
Afonso I (Portuguese pronunciation: [ɐˈfõsu]; born 1106, 1109 or 1111; died 1185), also called Afonso Henriques, nicknamed the Conqueror (Portuguese: O Conquistador) by the Portuguese, and El-Bortukali (in Arabic البرتقالي "the Portuguese") and Ibn-Arrink or Ibn Arrinq (in Arabic ابن الرَّنك or ابن الرَنْق "son of Henry", "Henriques") by the Moors whom he fought, 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 Teresa of León and Henry of Burgundy, rulers of the County of Portugal. Henry died in 1112, leaving Theresa to rule alone. Unhappy with Theresa'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. 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.
