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.
The French-speaking cities Neuchâtel, Geneva and Lausanne changed to the Reformation ten years later under William Farel and John Calvin coming from France.
A distinctive feature of the Swiss Reformed churches in the Zwinglian tradition is their historically almost symbiotic link to the state (cantons), which is only loosening gradually in the present.
They are governed synodically and their relation to the respective canton (in Switzerland, there are no church-state regulations at a national level) ranges from independent to close collaboration, depending on historical developments.
Pentecostal Protestantism reached Switzerland from the United States in the early 20th century, and is organized in the Schweizer Pfingstmission (since 1925).
