1919 Dublin University by-election
The 1919 Dublin University by-election was held on 28 July 1919. The by-election was held due to the appointment to the High Court of Justice in Ireland of the incumbent Irish Unionist MP, Arthur Samuels. It was uncontested and the Irish Unionist candidate William Jellett was elected. It was the last election to the UK Parliament to be held in the 26 counties that would become the Irish Free State in 1922.
