James Hamilton, Marquis of Hamilton had been elected as a Unionist in the 1910 general election, facing Nationalist opposition. He then succeeded to the Dukedom of Abercorn, resulting in the 1913 Londonderry City by-election, where the Roman Catholic hierarchy supported the Liberal David Hogg, a 73-year-old local shirt manufacturer and a Protestant.[3] Hogg died in August 1914 and the by-election was called for 30 November.
