About 1093 he married Teresa, the illegitimate daughter of Alfonso
          VI, King of Castile. In 1095 his father-in-law gave him the county of
          Portugal but as a typical knight he left his capable wife in charge to
          take part in the Second Crusade from 1103 to 1105.
              However, peace for Portugal lasted only until 1109. In that year
          King Alfonso VI of Castile died and his only legitimate child, his
          daughter Urraca, claimed all his territories including Portugal. This
          resulted in several years of civil war as well as war with the Moors.
          Henri died in 1112, leaving an only surviving son, Alfonso.
