Clan Douglas is a prominent Scottish clan with roots dating back to the 12th century. The clan's name is derived from the River Douglas in South Lanarkshire, Scotland. Historically, the Douglases were influential landowners and played significant roles in Scottish politics and warfare, particularly during the Wars of Scottish Independence. The clan's motto is "Amo" which means "I love," and its crest features a silver heart. The most famous member of Clan Douglas is James Douglas, known as the Black Douglas, who was a loyal supporter of Robert the Bruce during the fight for Scottish independence.
