What city, thanks to the activities of J. Calvin, turned into one of the most important centers of the Reformation?

The answer is Geneva. During the residence of John Calvin in this city, a kind of theocratic dictatorship was established here, since the local state structure began to have a strict religious character. The very leader of the Reformation began to be called the “Pope of Geneva”. Here, John Calvin presented his own draft of the church charter. He also opened the Geneva Academy, which was the highest theological institution and was created to carry out the training of Protestant preachers.
