Why was the Home Rule Act of 1914 never put into effect?

The Home Rule Act of 1914, formally known as the Government of Ireland Act, was enacted on September 18, 1914, but it was never put into effect because it was immediately suspended for the duration of World War I.123

At the time of its passage, Ireland was on the brink of civil war due to intense opposition from unionists, who had formed the Ulster Volunteer Force to resist the act, and nationalists, who had created the Irish Volunteers as a counterforce. To manage this volatile situation and focus on the British war effort, Prime Minister H.H. Asquith accompanied the act with a Suspensory Act, postponing its implementation.23

Following the war, the political landscape in Ireland changed drastically due to the 1916 Easter Rising and the rise of Sinn Féin, which sought full independence rather than the limited autonomy offered by Home Rule. Consequently, the 1914 act was never implemented, eventually being superseded by the Government of Ireland Act (1920) and the Anglo-Irish Treaty of 1921.231
