The gradual dispossession of large holdings belonging to several hundred native Roman Catholic landowners in Ireland took place in various stages from the reigns of the Roman Catholic Mary I and her Protestant half-sister Elizabeth I onwards. Unsuccessful revolts against English rule in 1595–1603 and 1641–53 and then the 1689–91 Williamite Wars caused much Irish land to be confiscated by the Crown, and then sold to people who were thought loyal, most of whom were English and Protestant. English soldiers and traders became the new ruling class, as its richer members were elevated to the Irish House of Lords and eventually controlled the Irish House of Commons (see Plantations of Ireland). This class became collectively known as the Anglo-Irish.
