The Irish National Land League (Irish: Conradh na Talún) was an Irish political organisation of the late 19th century which sought to help poor tenant farmers. Its primary aim was to abolish landlordism in Ireland and enable tenant farmers to own the land they worked on. The period of the Land League's agitation is known as the Land War. Historian R. F. Foster argues that in the countryside the Land League "reinforced the politicization of rural Catholic nationalist Ireland, partly by defining that identity against urbanization, landlordism, Englishness and—implicitly—Protestantism." Foster adds that about a third of the activists were Catholic priests, and Archbishop Thomas Croke was one of its most influential champions.
Following the founding meeting of the Mayo Tenants Defence Association in Castlebar, County Mayo on 26 October 1878 the demand for The Land of Ireland for the people of Ireland was reported in the Connaught Telegraph 2 November 1878.
The first of many "monster meetings" of tenant farmers was held in Irishtown near Claremorris on 20 April 1879, with an estimated turnout of 15,000 to 20,000 people. This meeting was addressed by James Daly (who presided), John O'Connor Power, John Ferguson, Thomas Brennan, and J. J. Louden.
The Connaught Telegraph's report of the meeting in its edition of 26 April 1879 began:
Since the days of O'Connell a larger public demonstration has not been witnessed than that of Sunday last. About 1 o'clock the monster procession started from Claremorris, headed by several thousand men on foot – the men of each district wearing a laural leaf or green ribbon in hat or coat to distinguish the several contingents. At 11 o'clock a monster contingent of tenant-farmers on horseback drew up in front of Hughes's hotel, showing discipline and order that a cavalry regiment might feel proud of. They were led on in sections, each having a marshal who kept his troops well in hand. Messrs. P.W. Nally, J.W. Nally, H. French, and M. Griffin, wearing green and gold sashes, led on their different sections, who rode two deep, occupying, at least, over an Irish mile of the road. Next followed a train of carriages, brakes, cares, etc. led on by Mr. Martin Hughes, the spirited hotel proprietor, driving a pair of rare black ponies to a phæton, taking Messrs. J.J. Louden and J. Daly. Next came Messrs. O'Connor, J. Ferguson, and Thomas Brennan in a covered carriage, followed by at least 500 vehicles from the neighbouring towns. On passing through Ballindine the sight was truly imposing, the endless train directing its course to Irishtown – a neat little hamlet on the boundaries of Mayo, Roscommon, and Galway.
