1917 North Roscommon by-election
The North Roscommon by-election of 1917 was held on 3 February 1917. The by-election was held due to the death of the incumbent Irish Parliamentary MP, James Joseph O'Kelly. It was won by the Sinn Féin candidate Count George Noble Plunkett,[1] the father of Joseph Plunkett who was shot for his role in the Easter Rising.
It was Sinn Fein's first victory for a Parliamentary election and would presage the virtual clean sweep of Southern Irish seats in the 1918 general election in Ireland.
