Protestantism in Switzerland

The Reformed branch of Protestantism in Switzerland was started in Zürich by Huldrych Zwingli and spread within a few years to Basel (Johannes Oecolampadius), Bern (Berchtold Haller and Niklaus Manuel), St. Gallen,(Joachim Vadian), to cities in southern Germany and via Alsace (Martin Bucer) to France.

Since 1920, the Swiss Reformed Churches have been organized in 26 member churches of the Federation of Swiss Protestant Churches. In the 2000 Swiss census, 33% of Swiss population were reported as registered members of a Reformed cantonal church. By 2022, this was 22.5%,^[1] with 2.7% of the populations belonging to other Protestant denominations.
