 After religious tensions erupted in widespread deadly violence against Protestant Christians in France, Calvin fled to Basel, Switzerland, where in 1536 he published the first edition of the "Institutes".In that same year, Calvin was recruited by Frenchman William Farel to join the Reformation in Geneva, where he regularly preached sermons throughout the week; but the governing council of the city resisted the implementation of their ideas, and both men were expelled.At the invitation of Martin Bucer, Calvin proceeded to Strasbourg, where he became the minister of a church of French refugees.
