About William Waller
Sir William Waller JP was an English soldier and politician, who commanded Parliamentarian armies during the First English Civil War. Elected MP for Andover to the Long Parliament in 1640, Waller relinquished his military positions under the Self-denying Ordinance in 1645. Although deeply religious and a devout Puritan, he belonged to the moderate Presbyterian faction, who opposed the involvement of the New Model Army in politics post 1646. As a result, he was one of the Eleven Members excluded by the army in July 1647, then again by Pride's Purge in December 1648 for refusing to support the Trial of Charles I, and his subsequent execution in January 1649.
