Land Acts (Ireland) in the context of "Three Fs"

The United Kingdom of Great Britain and Ireland was the union of the Kingdom of Great Britain and the Kingdom of Ireland into one sovereign state, established by the Acts of Union in 1801. It continued in this form until 1927, when it evolved into the United Kingdom of Great Britain and Northern Ireland, after the Irish Free State gained a degree of independence in 1922.

Rapid industrialisation that began in the decades prior to the state's formation continued up until the mid-19th century. The Great Irish Famine, exacerbated by government inaction in the mid-19th century, led to demographic collapse in much of Ireland and increased calls for Irish land reform. The 19th century was an era of Industrial Revolution, and growth of trade and finance, in which Britain largely dominated the world economy. Outward migration was heavy to the principal British overseas possessions and to the United States.

The Land War (Irish: Cogadh na Talún) was a period of agrarian agitation in rural Ireland (then wholly part of the United Kingdom) that began in 1879. It may refer specifically to the first and most intense period of agitation between 1879 and 1882, or include later outbreaks of agitation that periodically reignited until 1923, especially the 1886–1891 Plan of Campaign and the 1906–1909 Ranch War. The agitation was led by the Irish National Land League and its successors, the Irish National League and the United Irish League, and aimed to secure fair rent, free sale, and fixity of tenure for tenant farmers and ultimately peasant proprietorship of the land they worked.

From 1870, various governments introduced a series of Land Acts that granted many of the activists' demands. William O'Brien played a leading role in the 1902 Land Conference to pave the way for the most advanced social legislation in Ireland since the Union, the Land Purchase (Ireland) Act 1903. This Act set the conditions for the break-up of large estates by government-sponsored purchase.
