During the 17th century, this division between a Protestant landholding minority and a dispossessed Catholic majority was intensified and conflict between them was to become a recurrent theme in Irish history. Domination of Ireland by the Protestant Ascendancy was reinforced after two periods of religious war, the Irish Confederate Wars in 1641-52 and the Williamite war in 1689-91. Political power thereafter rested almost exclusively in the hands of a minority Protestant Ascendancy, while Catholics and members of dissenting Protestant denominations suffered severe political and economic privations under the Penal Laws.
