1924 and Liam Tobin coups W.T.Cosgrave as a reaction to Cosgrave's attempts to decrease the size of the army and creates a 'National Salvation' Government of various Nationalists, Republicans and Pro-Catholics which bans all Left Wing parties and imposes authoritarian measures across the nascent Irish Free State. The 1924 election is a sham, though popular support for Eoin O'Duffy and his National Party leads to O'Duffy being essentially disappeared by Tobin. The next 12 years essentially are Military imposed rule, with elections consisting of Government approved Candidates or Parties, the nation being reformed to something similar to a Corporatist model and Tobin even becomes friendly with the Mussolini regime whilst planning for the eventual time he can take Northern Ireland from the British. 1936 Tobin goes back to Military matters and imposes his puppet Joseph McGarth, Director of Intelligence (and head of Tobin's Secret Police) to run the nation as Prime Minister. However in the background, a conspiracy formed by Minster for the Interior Ernest Blythe, Gearóid Ó Cuinneagáin of the Ailtirí na hAiséirghe and Minister for Communication James Walsh who viewed McGarth as not pushing forward Irish values properly (evidence being McGarth not joining Italy in supplying troops to the Spanish Civil War and generally being more of a Nationalist Conservative than a Fascist for there liking). McGarth's suspicious death from a car crash in 1940 allows Ernest Blythe to take over and purge all those deemed insufficient in ideological loyalty to the Irish State and an increase in arrests of Protestants, Jews and other 'undesirables' occurs.
In late 1940, the Irish Republic joins the Axis and declares war on Britain. Despite German support, the war effort doesn't go to plan and by late 1943 British and American forces alongside the IRA manage to push the combined Irish/German force out of Northern Ireland and within a year Ernest Blythe is up against a wall and the Irish Republic has collapsed. A combined British,American and IRA committee is awkwardly created to oversee the tasks of rebuilding the country and reviving Democracy in Ireland. In 1946, with the war now over and Ireland beginning to return back to normalcy an election is called with James Dillon, a fierce critic of the Tobin/McGarth/Blythe regime becoming Prime Minister with his Renua party (a coalition of Conservatives, Liberals and Conservative Irish Labour Party members) as he enters into a coalition with the revived Sinn Féin (representing the Conservative wing of the IRA) being a coalition partner. Dillon's Paternalistic Conservative rule is about rebuilding more than anything and he handily wins the 1950 election on a 'Steady as she goes' manifesto (though the Daonlathaigh Shóisialta now having secured a footing becomes the main force of opposition to Renua with it's brand of Irish Social Democracy).
However it isn't long into his new leadership that he's assassinated by Gearóid Ó Cuinneagáin's Far Right Terrorist organisation Bráithreachas and into the breach steps James Everett, Minister for Labour. Everett's run as leader is more of the same (alongside a crackdown on the Irish Right) but delivered without the same enthusiasm and fire that Dillon had and it's unsurprising when Seán MacBride became Prime Minister in 1953. Stronger trade unions, Land Reform and implementation of a welfare state similar to the one implemented by the Attlee Government in Britain though much of MacBride's two governments is more concerned with supporting farmers and the creation of the Irish Environmental Trust and the Irish Farmer Grant scheme alongside Irish Welfare State reforms due to his coalition partner being the Populist Agrarian Left Wing party Clann na Talmhan. MacBride leaves his Prime Ministership a popular man (which would allow him to successfully become President the following year thanks to Margaret Mary Pearse stepping down) and is replaced by the more radical Brendan Corish who enters into a coalition with the Democratic Socialist/'De Leonist' Irish Workers Party and focuses on reforming the New Welfare State into a more radical Democratic Socialist angle (giving Trade Unions more power and implementing elements of Industrial Democracy) similar to his reforms of the National Health Corporation into the National Health Service (inspired by Britain's National Health Service) which allows him to reduce the attraction of the Pro-Soviet Saor Éire party.
Winning the 1963 election Brendan Corish promises to implement more change, though he's dealing with a revived Renua under Liam Cosgrave who many guess may win the next election if he plays it smart.
