Irish republican in the context of "Irish unionist"

Unionism in Ireland is a political tradition that professes loyalty to the crown of the United Kingdom and to the union it represents with England, Scotland and Wales. The overwhelming sentiment of Ireland's Protestant minority, unionism mobilised in the decades following Catholic Emancipation in 1829 to oppose restoration of a separate Irish parliament. Since Partition in 1921, as Ulster unionism its goal has been to retain Northern Ireland as a devolved region within the United Kingdom and to resist the prospect of an all-Ireland republic. Within the framework of the 1998 Belfast Agreement, which concluded three decades of political violence, unionists have shared office with Irish nationalists in a reformed Northern Ireland Assembly. As of February 2024, they no longer do so as the larger faction: they serve in an executive with an Irish republican (Sinn Féin) First Minister.

Unionism became an overarching partisan affiliation in Ireland late in the nineteenth century. Typically Presbyterian agrarian-reform Liberals coalesced with traditionally Anglican, Orange Order allied, Conservatives against the Irish Home Rule Bills of 1886 and 1893. Joined by loyalist labour, on the eve of World War I this broad opposition to Irish self-government concentrated in Belfast and its hinterlands as Ulster unionism and prepared an armed resistance—the Ulster Volunteers.

The Provisional Irish Republican Army (Provisional IRA), officially known as the Irish Republican Army (IRA; Irish: Óglaigh na hÉireann) and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent republic encompassing all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, the sole legitimate successor to the original IRA from the Irish War of Independence. It was designated a terrorist organisation in the United Kingdom and an unlawful organisation in the Republic of Ireland, both of whose authority it rejected.

The Provisional IRA emerged in December 1969, due to a split within the previous incarnation of the IRA and the broader Irish republican movement. It was initially the minority faction in the split compared to the Official IRA but became the dominant faction by 1972. The Troubles had begun shortly before when a largely Catholic, nonviolent civil rights campaign was met with violence from both Ulster loyalists and the Royal Ulster Constabulary (RUC), culminating in the August 1969 riots and deployment of British soldiers. The IRA initially focused on defence of Catholic areas, but it began an offensive campaign in 1970 that was aided by external sources, including Irish diaspora communities within the Anglosphere, and the Palestine Liberation Organization and Libyan leader Muammar Gaddafi. It used guerrilla tactics against the British Army and RUC in both rural and urban areas, and carried out a bombing campaign in Northern Ireland and England against military, political and economic targets, and British military targets in mainland Europe. They also targeted civilian contractors to the British security forces. The IRA's armed campaign, primarily in Northern Ireland but also in England and mainland Europe, killed over 1,700 people, including roughly 1,000 members of the British security forces and 500–644 civilians.

Principle of consent is a term used in the context of the Northern Ireland peace process and is one of the key points of the Good Friday Agreement. The principle asserts both the legitimacy of the aspiration to a United Ireland and the legitimacy of the wish of the majority of the people of Northern Ireland to remain part of the United Kingdom. The doctrine also asserts the right of self-determination for the people of both jurisdictions in Ireland, Northern Ireland and the Republic of Ireland, without external interference, and only with the consensus of a majority of people in both polities.

The principle of consent is now accepted by all elected parties in Ireland. It is opposed by Republican Sinn Féin, the Irish Republican Socialist Party, Éirígí and many non-aligned Irish republicans.

Sinn Féin (/ʃɪn ˈfeɪn/ shin FAYN; Irish: [ˌʃɪn̠ʲ ˈfʲeːnʲ] ; lit. '[We] Ourselves') is an Irish republican and democratic socialist political party active in both the Republic of Ireland and Northern Ireland.

The original Sinn Féin organisation was founded in 1905 by Arthur Griffith. Its members founded the revolutionary Irish Republic and its parliament, the First Dáil, and many of them were active in the Irish War of Independence, during which the party was associated with the Irish Republican Army (1919–1922). The party split before the Irish Civil War and again in its aftermath, giving rise to the two traditionally dominant parties of Irish politics: Fianna Fáil, and Cumann na nGaedheal (which merged with smaller groups to form Fine Gael). For several decades the remaining Sinn Féin organisation was small and often without parliamentary representation. It continued its association with the Irish Republican Army. Another split in 1970 at the start of the Troubles led to the modern Sinn Féin party, with the other faction eventually becoming the Workers' Party.

Ulster loyalism is a strand of Ulster unionism associated with working class Ulster Protestants in Northern Ireland. Like other unionists, loyalists support the continued existence of Northern Ireland (and formerly all of Ireland) within the United Kingdom, and oppose a united Ireland independent of the UK. Unlike other strands of unionism, loyalism has been described as an ethnic nationalism of Ulster Protestants and "a variation of British nationalism". Loyalists are often said to have a conditional loyalty to the British state so long as it defends their interests. They see themselves as loyal primarily to the Protestant British monarchy rather than to British governments and institutions, while Garret FitzGerald argued they are loyal to 'Ulster' over 'the Union'. A small minority of loyalists have called for an independent Ulster Protestant state, believing they cannot rely on British governments to support them (see Ulster nationalism). The term 'loyalism' is usually associated with paramilitarism.

Ulster loyalism emerged in the late 19th century, in reaction to the Irish Home Rule movement and the rise of Irish nationalism. Ireland had a Catholic majority who wanted self-government, but the province of Ulster had a Protestant and unionist majority, largely due to the Plantation of Ulster. Although not all unionists were Protestant, loyalists emphasised their British Protestant heritage. During the Home Rule Crisis (1912–14), loyalists founded the paramilitary Ulster Volunteers to prevent Ulster from becoming part of a self-governing Ireland. This was followed by the Irish War of Independence (1919–21) and partition of Ireland: most of Ireland became an independent state, while most of Ulster remained within the UK as the self-governing territory of Northern Ireland. During partition, communal violence raged between loyalists and Irish nationalists in Belfast, and loyalists attacked the Catholic minority in retaliation for Irish republican activity.

The Fenian Brotherhood (Irish: Bráithreachas na bhFíníní) was an Irish republican organisation founded in the United States in 1858 by John O'Mahony and Michael Doheny. It was a precursor to Clan na Gael, a sister organisation to the Irish Republican Brotherhood (IRB). Members were commonly known as "Fenians". O'Mahony, who was a Gaelic scholar, named his organisation after the Fianna, the legendary band of Irish warriors led by Fionn mac Cumhaill.

The Official Irish Republican Army or Official IRA (OIRA; Irish: Óglaigh na hÉireann) was an Irish republican paramilitary group whose goal was to remove Northern Ireland from the United Kingdom and create a "workers' republic" encompassing all of Ireland. It emerged in December 1969, shortly after the beginning of the Troubles, when the Irish Republican Army (IRA) split into two factions. The other was the Provisional IRA. Each continued to call itself simply "the IRA" and rejected the other's legitimacy.

Unlike the "Provisionals", the "Officials" did not think that Ireland could be unified until the Protestant majority and Catholic minority of Northern Ireland were at peace. The Officials were Marxist–Leninists and worked to form a united front with other Irish communist groups, named the Irish National Liberation Front (NLF). The Officials were called the NLF by the Provisionals and "stickies" by nationalists in Belfast (apparently in reference to members who would glue Easter lilies to their uniforms), and they were sometimes nicknamed the "Red IRA" by others.
