FTP, name this successor to Edward the Confessor who lost to William the Conqueror at Hastings.
Following a pilgrimage to Rome, he returned to England and completed his church at Waltham.  His first wife, nicknamed "Swan-neck," bore the same name as his second wife, Ealdgyth, and he was actually married to both at the same time.  His military successes included putting down a Welsh rebellion led by Gruffyd and later a Northumbrian rebellion, which resulted in his brother, Tostig's, banishment.  Tostig returned with a Norwegian army commanded by King Hardraade, but this king defeated them decisively at Stamford Bridge.  Alas, he would be killed four days later in a more famous battle.
