This article gives an overview of liberalism and the historical radicalism movement within liberalism in Switzerland. It is limited to liberal and radicalparties with substantial support, mainly proved by having had a representation in parliament. The sign ⇒ means a reference to another party in that scheme. For inclusion in this scheme it is not necessary that parties labeled themselves as a liberal party.
