and early 20th centuries, a period known to scholars as the Gaelic Revival (Athbheochan na Gaeilge). As a result, political, legal and economic power resided with the Ascendancy to the extent that by the mid-18th century, the greater part of the land in Ireland (97% in 1870) was owned by men who rented it out to tenant farmers rather than cultivating it themselves. Smaller landlords in the east, in Ulster or on the outskirts of towns were more favourably placed than the owners of tracts of infertile bog in the west. In 1870 302 proprietors (1.5% of the total) owned 33.7% of the land, and 50% of the country was in the hands of 750 families of the Ascendency. At the other end of the scale, 15,527 (80.5%) owned between them only 19.3% of the land. 95% of the land of Ireland was calculated to be under minority control of those within the established church. Absenteeism is accepted as having been an almost universal practice in Ireland and detrimental to the country's progress. Reform, though not complete, came in three main stages and was effected over 50 years: Reform of religious disabilities in 1778–82, allowing bishops, schools and convents. Reform of restrictions on property ownership and voting in 1778–93. Restoration of political, professional and office-holding rights in 1793–1829. Grattan's parliament The confidence of the Ascendancy was manifested towards the end of the 18th century by its adoption of a nationalist Irish, though still exclusively Protestant, identity and the formation in the 1770s of Henry Grattan's Patriot Party. The formation of the Irish Volunteers to defend Ireland from French invasion during the American Revolution effectively gave Grattan a military force, and he was able to force Britain to concede a greater amount of self-rule to the Ascendancy. The parliament repealed most of the Penal Laws in 1771–93 but did not abolish them entirely. Grattan sought Catholic emancipation for the catholic middle classes from the 1780s, but could not persuade a majority of the Irish MPs to support him. After the forced recall of the liberal Lord Fitzwilliam in 1795 by conservatives, parliament was effectively abandoned as a vehicle for change, giving rise to the United Irishmen – liberal elements across religious, ethnic, and class lines who began to plan for armed rebellion. The resulting and largely Protestant-led rebellion was crushed; the Act of Union of 1801 was passed partly in response
