Sancho I of Portugal
King of Portugal (1185–1211)
Sancho I (born Martinho; Coimbra, 11 November 1154 – 26 March 1211) also referred to as Sancho the Populator ("Sancho o Povoador"), was King of Portugal from 1185 until his death in 1211. He was the second king of Portugal.
Sancho was the second but only surviving legitimate son and fifth child of Afonso I of Portugal by his wife, Matilda of Savoy. Sancho succeeded his father and was crowned in Coimbra when he was 31 years old on 9 December 1185. He used the title King of Silves from 1189 until he lost the territory to Almohad control in 1191.
Early life
Sancho was baptized with the name Martin (Martinho) since he was born on the feast day of Saint Martin of Tours. On 15 August 1170, he was knighted by his father, King Afonso I, and from then on he became his second in command, both administratively and militarily. At this time, the independence of Portugal (declared in 1139) was not firmly established. The kings of León and Castile were trying to re-annex the country and the Roman Catholic Church was late in giving its blessing and approval. Due to this situation Afonso I had to search for allies within the Iberian Peninsula.
