Richard I of England

King Richard I of England, aka "Richard the Lion-Hearted," (1157-1199) was a twelfth-century King of England who led Christian armies in the Third Crusade, was briefly deposed by his brother and King Philip II of France, defeated the usurpers and reclaimed his crown, and was killed in battle against the French in 1199. He spent less than one year of his ten-year reign inside his kingdom's borders.
