Founded in 1913, the Liberal Party initially had sections in Zürich, Schaffhausen, Fribourg, Grisons, and Bern, in addition to Romandy.

[1] However, most of its sections were dissolved during the First World War, and by 1919 the party was confined to four cantons (Geneva, Vaud, Neuchâtel and Basel-City).

[1] In the 1960s, the Liberal Party tried to expand its influence beyond the four cantons, renaming itself the "Liberal-Democratic Union" from 1961 to 1977 in order to attract members from other regions.

[1] Although, since 1976, a Valais section had occupied a small place in the cantonal government, the party performed poorly in Basel-Country, Fribourg, Bern, Zurich.
