Emerging from the remnants of the Rassemblement autonome des gauches républicaines, the party positioned itself as a centre-right entity advocating for liberal and social-democratic ideals.
The European Liberal Party was created in 1960, continuing the ideological legacy of the Rally of Republican Lefts.
Pierre Marcilhacy, a prominent figure within the party, ran as its candidate in the 1965 French presidential election.
In 1973, the party affiliated itself with the Reformist Movement, a coalition of centrist and liberal political organizations.
Four years later, in 1977, it merged with the Radical Party, thereby ceasing its independent operations.
