1918 Sinn Féin election manifesto
Sinn Féin's manifesto for the 1918 general election was strongly separatist, continuing the party's policy of abstaining from the British parliament when elected and now pledging to create a new constituent assembly to establish the Irish Republic. After the party's reform in 1917, it campaigned against conscription in Ireland.
