lfonso I, Port. Afonso Henriques, 1111?-1185,
first king of Portugal, son of Henry of Burgundy. After his
father’s death (1112), his mother, Countess Teresa, ruled
the country of Portugal with the help of her Spanish favorite,
Fernando Pérez, until in 1128 young Alfonso, allying himself
with discontented nobles, took power and drove her into Leon with
Pérez (Alfonso did not, despite the popular legend, put her in
chains at Guimarãis). Beginning as little more than a quasi-independent
guerrilla chief, Alfonso spent his life in almost ceaseless
fighting against the kings of Leon and Castile and against the
Moors to increase his prestige and his territories. In 1139 he
defeated the Moors in the battle of Ourique (fought not at
Ourique, but at some undetermined place). In 1147 he took Santarém
by surprise attack and, with the help of the English, Flemish,
and German crusaders, captured Lisbon. Styling himself king after
1139, he put (1143) his lands under papal protection, and Alfonso
VII of Castile recognized the title, which was confirmed (1179)
by Pope Alexander III. Alfonso’s son Sancho I ascended an
established throne. [The Illustrated Columbia Encyclopedia, 1969]
