Australian Labor Party split of 1916: The Australian Labor Party split of 1916 occurred following severe disagreement within the Australian Labor Party over the issue of proposed World War I conscription in Australia.  Labor Prime Minister of Australia Billy Hughes had, by 1916, become an enthusiastic supporter of conscription as a means to boost Australia's contribution to the war effort.  On 30 August 1916, he announced plans for a referendum on the issue (the Australian plebiscite, 1916), and introduced enabling legislation into parliament on 14 September, which passed only with the support of the opposition.  Six of Hughes' ministers resigned in protest at the move, and the New South Wales state branch of the Labor Party expelled Hughes.  The referendum saw an intense campaign in which Labor figures vehemently advocated on each side of the argument, although the "no" campaign narrowly won on 14 November.  In the wake of the referendum defeat, the caucus moved to expel Hughes on 14 November; instead, he and 23 supporters resigned and formed the National Labor Party.  Frank Tudor was elected leader of the rump party.  Hughes was recommissioned as Prime Minister, heading a minority government supported by the opposition Commonwealth Liberal Party; the two parties then merged as the Nationalist Party of Australia and won the 1917 federal election.  The Nationalist Party served as the main conservative party of Australia until 1931, and the split resulted in many early Labor figures ending their careers on the political right.

The following year, he was elected as a ULP candidate, and retained his seat for that party (the Australian Labor Party from 1917) until 1931.
