The Irish Land League was a political organization founded in 1879 in Ireland to advocate for the rights of tenant farmers. It aimed to address issues such as high rents, eviction, and land ownership, promoting the idea that land should be owned by those who work it. The League's activities included organizing protests and campaigns to support tenants facing eviction. The movement gained significant support and led to the introduction of reforms, including the Land Act of 1881, which aimed to improve conditions for tenants. Key figures in the League included Charles Stewart Parnell, who played a crucial role in its leadership and strategy.
