formed a new party called Fianna Fáil ("Soldiers of Destiny"), taking most of Sinn Féin's TDs with him. In 1931, following the enactment of the Statute of Westminster, the country became a sovereign state along with the other Dominions and the United Kingdom. The following year, De Valera was appointed President of the Executive Council of the Free State and began a slow process of turning the country from a constitutional monarchy to a constitutional republic, thus fulfilling Collins's prediction of "the freedom to achieve freedom". By then, the IRA was engaged in confrontations with the Blueshirts, a quasi-fascist group led by a former War of Independence and pro-Treaty leader, Eoin O'Duffy. O'Duffy looked to Fascist Italy as an example for Ireland to follow. Several hundred supporters of O'Duffy briefly went to Spain to volunteer on the Nationalist side in the Spanish Civil War, and a smaller number of ex-IRA members, communists and others participated on the Republican side. In 1937, the Constitution of Ireland was drafted by the de Valera government and approved via referendum by the majority of the population of the Free State. The constitution changed the name of the state to in the Irish language (Ireland in English) and asserted its national territory as the whole of Ireland. The new state was headed by a President of Ireland elected by universal suffrage. The new Constitution removed all reference to the monarchy but foreign diplomats continued to present their credentials to the King in accordance with the Executive Authority (External Relations) Act 1936 which had not been repealed. The new state had the objective characteristics of a republic and was referred to as such by de Valera himself, but, it remained within the British Commonwealth and was regarded by the British as a Dominion, like Canada, Australia, New Zealand, and South Africa. Furthermore, the claim to the whole of the island did not reflect practical reality and inflamed anti-Dublin sentiment among northern Protestants. In 1948, Fianna Fáil went out of office for the first time in sixteen years. John A. Costello, leader of the coalition government, announced his intention to declare Ireland a republic. The Republic of Ireland Act 1948, which "described" the state as the Republic of Ireland (without changing its name or constitutional status), led the British government to pass the Ireland Act 1949, which declared that Northern Ireland would continue as part of the
