The term "Williamites" refers to the supporters of William of Orange, who became King of England in 1689 after the Glorious Revolution. They were primarily Protestant and opposed the Catholic King James II, advocating for a constitutional monarchy and religious tolerance. The Williamites played a significant role in the political and religious landscape of England and Ireland during this period. In Ireland, the Williamites are particularly associated with the Battle of the Boyne in 1690, where they fought against the forces loyal to James II. This battle was a pivotal moment in the struggle for control over Ireland and solidified Protestant dominance in the region. The legacy of the Williamites continues to influence Irish politics and culture today.
