The Reformed churches are churches that are part of the Calvinist branch of the Protestant Reformation. They include many European churches in Switzerland, Hungary, France, the Netherlands, Germany, and Scotland. The Presbyterian churches are part of the Reformed family. In the U.S. the Dutch Reformed Church and New England Puritans (Congregationalists) were an early presence, as were German Reformed churches and Presbyterians. Today the World Alliance of Reformed Churches, based in Geneva, includes Reformed churches from 86 countries.
