Land War in the context of "Irish Land League"

The Royal Irish Constabulary (RIC, Irish: Constáblacht Ríoga na hÉireann; simply called the Irish Constabulary 1836–67) was the police force in Ireland between 1822 and 1922, when all of the island was part of the United Kingdom. A separate civic police force, the unarmed Dublin Metropolitan Police (DMP), patrolled the capital, while the cities of Derry and Belfast, originally with their own police forces, later had special divisions within the RIC. For most of its history, the ethnic and religious makeup of the RIC broadly matched that of the Irish population, although Anglo-Irish Protestants were overrepresented among its senior officers.

The RIC was under the authority of the British administration in Ireland. It was a quasi-military police force. Unlike police elsewhere in the United Kingdom, RIC constables were routinely armed (including with carbines) and billeted in barracks, and the force had a militaristic structure. It policed Ireland during a period of agrarian unrest and Irish nationalist activity. It was used to quell civil unrest during the Tithe War, the Young Irelander Rebellion, the Fenian Rising, the Land War, and the Irish revolutionary period.

The Irish Republican Brotherhood (IRB; Irish: Bráithreachas Phoblacht na hÉireann) was a secret oath-bound fraternal organisation dedicated to the establishment of an "independent democratic republic" in Ireland between 1858 and 1924. Its counterpart in the United States of America and Canada was initially the Fenian Brotherhood, but from the 1870s it was Clan na Gael. The members of both wings of the movement are often referred to as "Fenians". The IRB played an important role in the history of Ireland, as the chief advocate of republicanism during the campaign for Ireland's independence from the United Kingdom, successor to movements such as the United Irishmen of the 1790s and the Young Irelanders of the 1840s.

As part of the New Departure of the 1870s–80s, IRB members attempted to democratise the Home Rule League and its successor, the Irish Parliamentary Party, as well as taking part in the Land War. The IRB staged the Easter Rising in 1916, which led to the establishment of the first Dáil Éireann in 1919. The suppression of Dáil Éireann precipitated the Irish War of Independence and the signing of the Anglo-Irish Treaty in 1921, ultimately leading to the establishment of the Irish Free State, which excluded the territory of Northern Ireland.

Free sale, fixity of tenure, and fair rent, also known as the Three Fs, were a set of demands first issued by the Tenant Right League during their campaign for land reform in Ireland starting in the 1850s. They were:

• Free sale—meaning a tenant could sell the interest in their holding to an incoming tenant without landlord interference;
• Fixity of tenure—meaning that a tenant could not be evicted if the rent was paid;
• Fair rent—meaning rent control: for the first time in the United Kingdom, fair rent would be decided by land courts, not by the landlords.

Many historians contend that their absence contributed significantly to the Great Irish Famine (1846–49), as it enabled the mass eviction of starving tenants. The Three Fs were advocated by several political movements, notably the Independent Irish Party (1852–1858) and later the Irish Parliamentary Party during the Land War (from 1878). The British Government conceded to these demands through a series of Irish Land Acts enacted from the 1870s onward, with nearly full implementation in the Land Law (Ireland) Act 1881.
