The House of Douglas was a prominent Scottish noble family that played a significant role in the history of Scotland from the 12th century onwards. Known for their military prowess and political influence, the Douglases were involved in various conflicts, including the Wars of Scottish Independence. They held vast estates and titles, including the Earldom of Douglas. The family's power peaked in the late 14th and early 15th centuries, but internal strife and rivalries led to their decline. The Black Douglas, a nickname for the family, is often associated with their fierce reputation. Ultimately, the House of Douglas was absorbed into the House of Stewart through marriage and political alliances.
