mar 26, 1541 - John Calvin's Geneva
Description:
John Calvin transformed Geneva into a modern Calvinist city-state. Geneva had a church government system and Calvin was not tolerant of heresy and blasphemy and harshly punished those who didn't conform to his religion. This fits with the OS theme because John Calvin had visions that differed from those of traditional Catholic authorities and even went as far as to challenge those Catholic beliefs.
