Federation of the Lefts

The Federation of the Lefts (Fédération des gauches) was a French electoral coalition during the French Third Republic founded in January 1914 by members of the Democratic Republican Alliance such Aristide Briand, Alexandre Millerand and Louis Barthou to provide a centrist alternative to the left's coalition, led by the Radical-Socialist Joseph Caillaux. However, the federation failed to attract the most moderate Radical voters and the left won the 1914 election which saw the centre fall back. The Federation was a failure.

However, a parliamentary group under the name Republican, Radical and Radical-Socialist Union (Union républicaine radicale et radicale-socialiste) was formed in the new legislature and held a relatively important position in the legislature.
