The Battle of the Boyne

1688 - 1691 — The war between James II and William of Orange, decided at the Boyne in 1690, with lasting consequences.

The Williamite War in Ireland (1688–1691) was fought between supporters of the Catholic King James II (the Jacobites) and the Protestant King William of Orange (the Williamites), as part of a wider European conflict.

The most famous clash, the Battle of the Boyne (Cath na Bóinne), was fought near Drogheda in July 1690 and won by William. The war ended with the Treaty of Limerick in 1691. Many defeated Jacobite soldiers left to serve in continental armies — the "Flight of the Wild Geese" — and the Protestant Ascendancy tightened its grip on Irish land and power.
