Sinn Féin had no official connection with the violence of the 1916 rising, but in the aftermath it was associated with the event by the press.
Sinn Féin's growth and popularity was further enhanced by the British threat in 1917-1918 to introduce conscription to Ireland in support of its war effort against Germany.
Provisional Sinn Féin's role was enhanced by the 1981 hunger strikes in Northern Ireland which ushered in a new policy of “the ballot box and the Armalite”, or in other words a strategy of a joint military and political campaign.
Sinn Féin (pronounced /ʃɪn feɪn/ in English, /ʃiːɲ fʲeːnʲ/ in Irish) is a name used by a series of Irish political movements of the 20th century, each of which claimed sole descent from the original party established by Arthur Griffith in 1905.
Sinn Féin was boosted by the anger over the execution of Rising leaders, even though before the executions, the Roman Catholic hierarchy, the Irish Independent newspaper (the biggest selling daily newspaper in Ireland then and now) and many local authorities actually called for the mass execution of Rising leaders.
Sinn Féin won 73 of Ireland's 106 seats in the United Kingdom of Great Britain and Ireland parliament at the general election in December 1918 and many of the seats it won were uncontested.
