In 1922 the
pro-Treaty Government of the Irish Free State lost the support of
Sinn Féin, its political party. The need to create a party supporting the government was not immediate.
Cumann na nGaedheal was the name of the antecedent nationalist
umbrella organisation to Sinn Féin formed in 1900 (see
Cumann na nGaedheal (1900)). The second
Cumann na nGaedheal did not come into existence until more than a year later, on 27 April 1923 when the pro-Treaty
TDs recognised the need for a party organisation to win elections. Initially, the party's ability to influence the government was limited. The party was largely centre-right in outlook. The pro-Treaty wing of Sinn Féin had decided to break off and become a distinct party in late December 1922, but its launch was delayed until after the New Year as a direct consequence of the turmoil caused by the
Irish Civil War. The leadership of the pro-Treaty Sinn Féin in 1922 included
Arthur Griffith,
Michael Collins and
W. T. Cosgrave. Cosgrave and Griffith had been prominent in Sinn Féin since the 1900s, while Collins rose quickly through its ranks after the 1916
Easter Rising. Griffith and Collins died in August 1922 during the early stages of the Civil War, leaving Cosgrave to lead the pro-Treaty Provisional Government in the run-up to the formal establishment of the
Irish Free State. Cosgrave had also fought in the Easter Rising and had been prominent in the Government of the
Irish Republic; the burden of responsibility for building the new
state on solid foundations was now on Cosgrave and his colleagues. Difficult years of state-building amidst
political violence characterised its time in government. The
Irish Unionist Alliance was dissolved in 1922, when many of its followers swung their support behind Cumann na nGaedheal, seeing it as less hostile to them than the anti-Treaty
Republicans and the later
Fianna Fáil. When the
first Seanad was formed, half of the seats were filled by unionists nominated by the Cumann na nGaedheal government. Prominent Southern Unionist politicians, like
Maurice Dockrell,
Richard Beamish and
Bryan Cooper, supported the party. ==State building and reconstruction==
