Michael Collins (Irish leader)
Collins, like many of the other participants, was arrested, almost executed. He was imprisoned at Frongoch internment camp. Collins became one of the leading figures in Sinn Féin after the Rising. This was a small nationalist party which the British government and the Irish media mistakenly accredited the Rising to. By October 1917, Collins had become a member of the executive of Sinn Féin and Director of Organisation of the Irish Volunteers. Éamon de Valera was president of both organisations.
