The Irish National Land League was founded in 1879 to address the issues of land ownership and tenant rights in Ireland. It aimed to improve the conditions for tenant farmers who faced high rents and eviction. The League advocated for land reform, promoting the idea that land should be owned by those who worked it. The movement gained significant support and led to the Land War, a period of agitation and protests against landlords. Key figures, such as Charles Stewart Parnell, played a crucial role in the League's activities, which ultimately contributed to important legislative changes in land policy in Ireland.
