The peace Treaty of Limerick signed on 3 October 1691 offered favourable terms to Jacobites willing to stay in Ireland and give an oath of loyalty to William III. Peace was concluded on these terms between Sarsfield and Ginkell, giving toleration to Catholicism and full legal rights to Catholics that swore an oath of loyalty to William III and Mary II. The Protestant-dominated Irish Parliament refused to ratify the articles of the Treaty in 1697, and from 1695 on, updated the penal laws, which discriminated harshly against Catholics. Catholics saw this as a severe breach of faith. A popular contemporary Irish saying was, cuimhnigí Luimneach agus feall na Sassanaigh . The Papacy was an enemy of Louis of France and therefore did not support James in 1691, but the new Pope Pope Innocent XII changed its policy to support for France, and therefore James, from 1693. This factor hardened Protestant attitudes towards Catholics and Jacobitism in Ireland. Part of the treaty agreed to Sarsfield's demand that the Jacobite army could leave Ireland as a body and go to France. Ships were even provided for this purpose. This event was popularly known in Ireland as the "Flight of the Wild Geese". Around 14,000 men with around 10,000 women and children left Ireland with Patrick Sarsfield in 1691. Initially, they formed the army in exile of James II, though operating as part of the French army. After James' death, the remnants of this force merged into the French Irish Brigade, which had been set up in 1689 from 6,000 Irish recruits sent by the Irish Jacobites in return for French military aid.
