Archibald Campbell, 1st Marquess of Argyll

Archibald Campbell, 1st Marquess of Argyll was a Scottish nobleman, politician, and peer. The de facto head of Scotland's government during most of the conflict of the 1640s and 1650s known as the Wars of the Three Kingdoms, he was the main leader of the Covenanter movement that fought for the Establishment of Presbyterianism in opposition to the preference of King Charles I and the Caroline Divines for instead establishing both High Church Anglicanism and Bishops. He is often remembered as the principal antagonist to the Royalist general James Graham, 1st Marquess of Montrose.
