Early political activity

While he was already involved in the Gaelic revival, de Valera's involvement in the political revolution began on 25 November 1913, when he joined the Irish Volunteers. The organisation was formed to oppose the Ulster Volunteers and ensure the enactment of the Irish Parliamentary Party 's Third Home Rule Act won by its leader John Redmond. After the outbreak of World War I in August 1914, de Valera rose through the ranks and it was not long before he was elected captain of the Donnybrook branch. Preparations were pushed ahead for an armed revolt, and he was made commandant of the Third Battalion and adjutant of the Dublin Brigade. He took part in the Howth gun-running. He was sworn by Thomas MacDonagh into the oath-bound Irish Republican Brotherhood, which secretly controlled the central executive of the Volunteers. He opposed secret societies, but this was the only way he could be guaranteed full information on plans for the Rising.
