On September 25, 1917, Éamon de Valera presided over a pivotal Sinn Féin convention in Dublin. This gathering was instrumental in reorganizing the party's structure and refining its political strategy following the 1916 Easter Rising. The convention solidified Sinn Féin's transformation into the dominant force in Irish nationalist politics, advocating for an independent Irish Republic. De Valera's leadership and the party's renewed focus on abstentionism from the British Parliament and the establishment of an Irish constituent assembly marked a significant shift towards a more radical and unified approach to achieving Irish self-determination.
