Afonso II (IPA: [ɐˈfõsu]; English: Alphonse; Archaic Portuguese: Affonso; Portuguese-Galician: Alfonso or Alphonso; Latin: Alphonsus; 23 April 1185[4] – 25 March 1223), nicknamed the Fat (o Gordo) or the Leper (o Gafo), was the third king of Portugal and the second but eldest surviving son of Sancho I of Portugal and Dulce of Aragon.

Hitherto, his father Sancho I and his grandfather Afonso I were mostly concerned with military issues either against the neighbouring Kingdom of Castile or against the Moorish lands in the south.

[5] This issue was in response to the church's rein over Portuguese land as they supported Afonso's fight in the civil war with Sancho II.

With Portugal's position as a country firmly established, Afonso II endeavoured to weaken the power of the clergy and to apply a portion of the enormous revenues of the Catholic Church to purposes of national utility.

[6] King Afonso was buried originally at the Monastery of Santa Cruz in Coimbra where his body remained for nearly ten years.
