King Fernando of Castile
King of Castile (1033-65) and of Leon (1037-65); he was the second son of King Sancho III
of Navarre. In 1037, Ferdinand
defeated Burmudo in a battle at Tamaron, acquiring Leon through Sancha's
right of succession. Ferdinand
won the Battle of Atapuerca over his brother in 1054 and was recognized as the emperor of Spain in 1056 by his territorial aquistions from the Moors of Spanish and from the Muslims. Before his death, Ferdinand
provided that his estates be divided among his three sons, thus bequeathing a legacy of fratricidal strife that did not end until the accession of Alfonso I
to the throne of Castile in 1072.
