In 1455, James Douglas, 9th Earl of Douglas (the Black Douglas) rebelled against the king but his forces were defeated at the Battle of Arkinholm by the king's forces who were commanded by George Douglas, 4th Earl of Angus (the Red Douglas). This brought an end to the Black Douglases. After the battle an act of parliament gave the Earl of Angus the lordship of Douglas with the original possessions of his ancestors in Douglasdale. The 9th Earl of Douglas was later defeated by the forces of King James III of Scotland at the Battle of Lochmaben Fair in 1484.
