Williamite
- Not to be confused with the mineral willemite.
A Williamite is a follower of King William III of England who deposed King James II in the Glorious Revolution. William, the Stadtholder of the Dutch Republic, replaced James with the support of English Whigs.
One of William's aims was to ensure England's entry into his League of Augsburg against France in the Nine Years War. For Williamites in England, Scotland and Ireland, William was seen as the guarantor of civil and religious liberty and the Protestant monarchy against Catholic absolutism.
