By this time access to institutional power in Ireland was restricted to a small minority, the Anglo-Irish of the Protestant Ascendancy, and frustration at the lack of reform among the Catholic majority eventually led, along with other reasons, to a rebellion in 1798, involving a French invasion of Ireland and the seeking of complete independence from Great Britain. This rebellion was crushed with much bloodshed, and the subsequent drive for union between Great Britain and Ireland that passed in 1800 was motivated at least in part by the belief that the rebellion was caused as much by reactionary loyalist brutality as by the United Irishmen.
