The Committee of Both Kingdoms, (known as the Derby House Committee from late 1647), was a committee set up during the Wars of the Three Kingdoms by the Parliamentarian faction in association with representatives from the Scottish Covenanters, after they made an alliance (the Solemn League and Covenant) in late 1643. A sub-committee on Irish affairs met from 1646 to 1648. The sub-committee spent, in Ireland, money raised by the Committee of Both Houses.
