Until 1801, Ireland continued to exist as a Kingdom in its own right, with its own Parliament. The government of Ireland, however, remained in English hands even after Grattan's constitution came into effect in the 1780s. Most of the country's population remained Catholic, but its Protestant minority remained socially, politically, and economically dominant; and even many Protestants were excluded from power as not being members of the established Church of Ireland. The Penal Laws preserving the position of the Protestant Ascendancy began to be dismantled in the 1780s and 1790s. However, fear of revolutionary violence in the wake of the French Revolution and the French Revolutionary Wars and subsequent republican Irish Rebellion of 1798 led the British government to seek the union of Ireland with Great Britain; this resulted in the formation of the United Kingdom of Great Britain and Ireland.
