Clan MacDougall is a Highland Scottish clan, historically based in and around Argyll. The Lord Lyon King of Arms who is the Scottish official with responsibility for regulating heraldry in that country, issuing new grants of coats of arms, and serving as the judge of the Court of the Lord Lyon, recognizes under Scottish law the Chief of Clan MacDougall. 

The MacDougall chiefs share a common ancestry with the chiefs of Clan Donald in descent from Somerled of the 12th century (and thus further of the Viking-born Norse-Gael dynasty of House of Ivar). 

In the 13th century the Clan MacDougall whose chiefs were the original Lords of Argyll and later Lords of Lorne was the most powerful clan in the Western Highlands. During the Wars of Scottish Independence the MacDougalls sided with the Clan Comyn whose chiefs rivaled Robert the Bruce for the Scottish Crown and this resulted in clan battles between the MacDougalls and Bruce. 

This marked the MacDougall's fall from power and led to the rise of their relatives, the Clan Donald, who had supported Bruce and also the rise to power of the Clan Campbell who were the habitual enemies of the MacDougalls and Clan Donald. The MacDougalls supported the House of Stuart during the Scottish Civil War of the 17th century and during the Jacobite risings of the 18th century. source: Wikipedia
