Circumstances placed John Redmond and the Irish Parliamentary Party at the center of British politics in 1912. After more than a century of struggle, Irish nationalists looked likely to return a parliament to Dublin that would allow the Irish people, as one nation, to determine their own domestic affairs. Staunch Ulster Unionists stood in opposition, determined to reject Home Rule for their region. Alongside them were Unionist Party members who declared that such an action would destroy the British Empire, wreck the constitution, and possibly foment a civil war. Over the next decade, the Home Rulers saw their cause betrayed and their party destroyed. Asquith, Lloyd George, and Winston Churchill all served to undercut Redmond and his supporters in the interests of political expediency. Four years of war in Europe, followed by four years of conflict in Ireland, led to a more radical approach to the Irish question that allowed Sinn Fein and the Irish Republican Army to make the nationalist cause their own. By 1922, Eamonde Valera, Michael Collins, James Craig and their followers took possession of a divided Ireland embittered by the enmity of two Irish identities and the strains of factional strife.
