Alfonso was the only son of King Ferdinand II of Leon and Urraca of Portugal. Though he took a part in the work of the reconquest, this king is chiefly remembered by the difficulties into which his successive marriages led him with the pope. He was first married in 1191 to his cousin Teresa of Portugal, who bore him two daughters, and a son who died young. Ferdinand II., king of Leon (d. ... Teresa of Leon is sometimes referred to as Teresa of Portugal Teresa of Portugal (1181 – June 18, 1250), also known as Tarasia of Portugal, was the oldest daughter of Sancho I of Portugal and wife of Alfonso IX of Castile. ...

The marriage was declared null by the pope, to whom Alfonso paid no attention till he was presumably tired of his wife. It cannot have been his conscience which constrained him to leave Teresa, for his next step was to marry Berenguela of Castile in 1197, who was his second cousin. For this act of contumacy the king and kingdom were placed under interdict. Berenguela (or Berengaria) ( 1180- November 8, 1246), was briefly queen of Castile and León. ...

The king was left under interdict personally, but to that he showed himself indifferent, and he had the support of his clergy. Berenguela left him after the birth of five children, and the king then returned to Teresa, to whose daughters he left his kingdom by will.

Alfonso's children were:

1. Fernando, died 1214
2. Sancha (c.1195-before 1243)
