The Tenant Right League was a federation of local societies formed in Ireland in the wake of the Great Famine to check the power of landlords and advance the rights of tenant farmers. An initiative of northern unionists and southern nationalists, it articulated a common programme of agrarian reform. In the wake of the League's success in helping return 48 pledged MPs to the Westminster Parliament in 1852, the promised unity of "North and South" dissolved. An attempt was made to revive the all-Ireland effort in 1874, but struggle for rights to the land was to continue through to the end of the century on lines that reflected the regional and sectarian division over Ireland's continued place in the United Kingdom.
