The Williamite War in Ireland begins on March 12, 1688. It is a conflict between Jacobites, who support the English Catholic King James II, and Williamites, who support the Dutch Protestant Prince William of Orange, over who would be King of England, Scotland, and Ireland.
The cause of the war is the deposition of James II as King of the Three Kingdoms in the “Glorious Revolution” of 1688. James is supported by the mostly Catholic Jacobites in Ireland and hopes to use the country as a base to regain his Three Kingdoms. He is given military support by France. For this reason, the war becomes part of a wider European conflict known as the Nine Years’ War, or War of the Grand Alliance. Some Protestants of the established Church in Ireland also fight on the side of King James.
James is opposed in Ireland by the mostly Protestant Williamites, who are concentrated in the north of the country. William lands a multi-national force in Ireland, composed of English, Scottish, Dutch, Danish, and other troops, to put down Jacobite resistance. James leaves Ireland after a reverse at the Battle of the Boyne in 1690 and the Irish Jacobites are finally defeated after the Battle of Aughrim in 1691.
The Treaty of Limerick, signed on October 3, 1691, offers favourable terms to Jacobites willing to stay in Ireland and give an oath of loyalty to William III. Peace is concluded on these terms between Patrick Sarsfield and Godert de Ginkell, giving toleration to Catholicism and full legal rights to Catholics that swear an oath of loyalty to William and Mary. Part of the treaty agreed to Sarsfield’s demand that the Jacobite army be allowed to leave Ireland as a body and go to France. This event is popularly known in Ireland as the “Flight of the Wild Geese.” Around 14,000 men with around 10,000 women and children leave Ireland with Patrick Sarsfield in 1691.
The Williamite victory in the war in Ireland has two main long-term results. The first is that it ensures James II will not regain his thrones in England, Ireland, and Scotland by military means. The second is that it ensures closer British and Protestant dominance over Ireland. Until the 19th century, Ireland is ruled by what becomes known as the “Protestant Ascendancy,” the mostly Protestant ruling class. The majority of the Irish Catholic community and the Ulster-Scots Presbyterian community are systematically excluded from power, which is based on land ownership.
For over a century after the war, Irish Catholics maintain a sentimental attachment to the Jacobite cause, portraying James and the Stuarts as the rightful monarchs who would have given a just settlement to Ireland, including self-government, restoration of confiscated lands and tolerance for Catholicism. Thousands of Irish soldiers leave the country to serve the Stuart monarchs in the Irish Brigade (Spanish) and Irish Brigade of the French Army. Until 1766, France and the Papacy remain committed to restoring the Stuarts to their British Kingdoms. At least one composite Irish battalion drawn from Irish soldiers in the French service fight on the Jacobite side in the Scottish Jacobite uprisings leading up to the Battle of Culloden in 1746.
Protestants, on the other hand, portray the Williamite victory as a triumph for religious and civil liberty where triumphant murals of King William still controversially adorn the gable walls in Ulster. The defeat of the Catholics in the Williamite war is still commemorated by Protestant Unionists in Ulster on the Twelfth of July by the Orange Order.
