Sancho I of Portugal

  • 1170: Knighted
  • 06 Dec 1185 - 26 Mar 1212: King of Portugal

Sancho I, nicknamed "the Populator" (Portuguese: "o Povoador"), King of Portugal, was the second but only surviving legitimate son and fifth child of Afonso I of Portugal by his wife, Maud 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.

With the death of Afonso I in 1185, Sancho I became the second king of Portugal. Coimbra was the centre of his kingdom; Sancho terminated the exhausting and generally pointless wars against his neighbours for control of the Galician borderlands. Instead, he turned all his attentions to the south, towards the Moorish small kingdoms (called taifas) that still thrived. With Crusader help he took Silves in 1188. Silves was an important city of the South, an administrative and commercial town with population estimates around 20,000 people. Sancho ordered the fortification of the city and built a castle which is today an important monument of Portuguese heritage. However, military attention soon had to be turned again to the North, where León and Castile threatened again the Portuguese borders. Silves was again lost to the Moors in 1191.

King Sancho had 19 children, eleven with his wife Princess Dulicia of Aragon:

i. Princess Teresa de Portugal, b. 1176, d. in the Convent of Lorvano 18 Jun 1250[1]Barcelos, p. 30.</ref>
