The revolution accomplished, William (now King of England) made Bentinck Groom of the Stole, first gentleman of the bedchamber, and a Privy Counsellor. In April 1689 he was created Baron Cirencester, Viscount Woodstock and, in its second creation, Earl of Portland. (The first creation of the earldom had been made for Richard Weston in 1633, but it became extinct in 1688.) He commanded some cavalry at the Battle of the Boyne in 1690, and was present at the Battle of Landen, where he was wounded, and at the Siege of Namur in 1695.
