Foundation The Irish Unionist Alliance was founded in 1891 by the members of the
Irish Loyal and Patriotic Union (ILPU), which it replaced. The ILPU had been established to prevent electoral competition between
Liberals and
Conservatives in the three southern provinces on a common platform of maintenance of the union. The IUA united this movement with unionists in the northern
province of
Ulster, where unionist sentiment and support was strongest. As such, the new party sought to represent unionism on an
all-Ireland basis. The party's founders hoped that this would coordinate the electoral and lobbying activities of unionists across Ireland. Prior to 1891, unionists had seen considerable electoral losses across southern Ireland at the hands of the pro-Home Rule
Irish Parliamentary Party, founded a decade earlier. It was deemed necessary for southern and northern supporters of the Union to more formally unite their efforts. At this stage, the majority of unionists in all parts of Ireland were opposed to the
Irish Home Rule movement, especially following the collapse of the Irish wing of the Liberal Party. It was during that this time that a large number of Conservative MPs married into Irish Southern Unionist families. Despite early hopes among some unionists that the IUA would expand the unionist presence across Ireland, the party failed to make any major electoral gains in the six subsequent general elections. In the south of Ireland, the IUA consistently won only the double seat representing the graduates of
Dublin University, and a couple of the
Dublin seats would occasionally fall to them. The party also won a surprise victory in
Galway Borough in 1900. In local elections, the party maintained a geographically broader representation, although failed to win many new voters. Unlike in Ulster, the anti-Home Rulers were a scattered minority. In Ulster, the IUA built upon solid unionist electoral foundations and became the dominant political force in much of the province. In the north and east of Ulster, unionists consistently won seats, often unopposed. Although Ulster Unionists were still within the broader framework of the Irish Unionist Alliance, the Ulster party began to develop its own distinct organisational structures and political goals. From 1907, the IUA's political activity was organised by the Joint Committee of the Unionist Associations of Ireland (JCUAI). This body sought to coordinate the IUA's election and lobbying activity, whilst recognising the distinct differences between the northern and southern parties. The prominence of the Ulster Unionist Council quickly grew thanks to the strong unionist sentiment in Ulster. From 1910, it became the dominant force and focus of resistance in the Irish unionist community. The JCUAI was effectively controlled by Ulstermen, while the IUA's leadership remained largely in the hands of Southern Unionists. This led to the unionist movement gradually becoming 'Ulsterised' from 1910, which marginalised many more moderate unionists in the south.
Division (1914–1922) By 1914, the conflict of interest between the unionists in southern Ireland and those in Ulster was wracking the IUA. It was known that the passage of a Home Rule Bill for Ireland was becoming increasingly likely, and as a result many Southern Unionists began to seek a political compromise which would see their interests protected. Many unionists in the south became strongly opposed to any plan to partition the island, as they knew that it would leave them isolated from the unionist-majority areas. Several prominent Southern Unionists, such as
Sir Horace Plunkett and
Lord Monteagle, became convinced that a degree of home rule was going to be necessary if Ireland was to avoid partition and remain in the Union. Others, such as the anti-partition party leader
the 9th Viscount Midleton (later created the 1st
Earl of Midleton in 1920), resented the growing dominance of Ulstermen in the party. Lord Midleton and his supporters feared that the Ulster wing of the party (now more formally organised as the
Ulster Unionist Party) would abandon the south in order to gain a favourable settlement for the north from the British government. In October 1913, the vice-chairman of the IUA,
G. F. Stewart, had written to its leader,
Sir Edward Carson, to complain that southern concerns were being ignored. Several large unionist demonstrations took place in Dublin in early 1914, in which protesters complained as much about the Ulster Unionists as the Irish nationalists. The internal divisions simmered during the
First World War. Southern Unionist members sided with
Irish Nationalists against the Ulster Unionists during the 1917–18
Irish Convention in an attempt to bring about an understanding on the implementation of the suspended
Home Rule Act 1914. The Alliance's official opposition to partition led to it being marginalised in the
1918 general election, which showed the rising influence of the
republican Sinn Féin party on the one hand and the strength of
Ulster Unionist Council on the other. Despite this, the Alliance won its largest number of seats, with the IUA candidate managing to win a surprise victory in
Rathmines. Against the backdrop of the subsequent
Irish War of Independence unionists began to openly disagree. At a meeting of the party on Molesworth Street, Dublin, on 24 January 1919, Lord Midleton proposed a motion to the party which would have denied Ulster Unionists a say on government proposals affecting the south of Ireland. Many ordinary members of the southern IUA (Protestant farmers, shopkeepers and clergymen) initially stayed with the remaining rump of the IUA in the south, led by
the 11th Baron Farnham, a
County Cavan landowner. and the
Irish Centre Party. As such, the southern rump of the IUA became increasingly fractured and in 1922 it lost its reason to exist with the establishment of the Irish Free State. Leading unionist figures, such as
the 1st Earl of Midleton (as he had become in 1920),
the 4th Earl of Dunraven and Mount-Earl,
the 1st Baron Glenavy and
Sir Horace Plunkett, were appointed in December 1922 by
W. T. Cosgrave to the
Free State's first Senate. Amongst others, Sir Horace Plunkett's home in
County Dublin was then
burnt down during the
Irish Civil War (1922–23) because of his involvement in the Irish Senate. The IUA helped form the Southern Irish Loyalist Relief Association to assist war refugees and claim compensation for damage to property. From 1921 IUA voters began to support the mainstream
Cumann na nGaedheal party. In the
1923 election three formerly loyalist businessmen were elected as the
Business and Professional Group. From 1921 to 1991 the proportion of Southern Irish Protestants declined from 10% to 3% of the population; these had provided the bulk of the IUA's support base. Unionists continued to have a majority on Rathmines Council until 1929, when the IUA's successors lost their last elected representatives in the Irish Free State.
Northern Ireland In
Northern Ireland, unionists of the
Ulster Unionist Party (UUP; previously known as the Ulster Unionist Council) continued to dominate domestic politics. The party would hold its powerful position in the unionist community for much of the rest of the twentieth century, until the rise of the
Democratic Unionist Party (DUP) in the late 1980s. ==General election results==
