The 1916 Rotherham by-election was a Parliamentary by-election held on 26 January 1916. The constituency returned one Member of Parliament (MP) to the House of Commons of the United Kingdom, elected by the first past the post voting system.
Vacancy.
Rt Hon. Jack Pease had been Liberal MP for the seat of Rotherham since the 1910 Rotherham by-election. In 1916, he was appointed Postmaster General, an office of profit under the Crown and therefore required to seek re-election.
Electoral history.
This was a safe Liberal seat and at the last General Election, Pease was re-elected comfortably;

Pease was made Baron Gainford in 1917 which resulted in the 1917 Rotherham by-election.
