What happened
In the wake of the Williamite War, the 1691 Treaty of Limerick had promised Catholics who accepted William and Mary a degree of religious toleration and the right to keep their estates, but the Protestant-dominated Irish Parliament ignored those terms within a few years. Starting in 1695, a series of Penal Laws stripped Irish Catholics of political and civil rights piece by piece: Catholic clergy above parish level were banished from Ireland on pain of imprisonment, Catholics were barred from Parliament, the judiciary, the army, and most paid public office, and Catholic landholders could not leave their entire estate to one heir unless he had converted to the Protestant Church of Ireland, forcing estates to fragment across generations of Catholic heirs. Catholics were also barred from keeping a Catholic schoolmaster or sending children abroad for a Catholic education without financial penalty. The cumulative effect over the following decades was a steep decline in Catholic-owned land in a country that remained overwhelmingly Catholic by population.
Why it matters
The Penal Laws systematically excluded the Catholic majority from property, education, and public life for the better part of a century, entrenching a Protestant landowning class, the ascendancy, whose position depended on legal disability rather than economic or numerical strength, a grievance that fed directly into the political movements of the following two centuries.
How we know
The Penal Laws survive as the actual statutes passed by the Irish Parliament during this period, and their content and application have been studied in detail by Irish legal historians using surviving land, inheritance, and court records.
