But though the Vaudois had been won over, Geneva was by no means secured for the reformers. Farel and his followers, finding themselves involved in serious difficulties, appealed to Calvin to help them in completing the work they had begun. In 1536 Calvin accepted this invitation, and took up his residence at Geneva. Gifted with great powers as an organiser and administrator he soon restored order in the city, and won over the people to his doctrines. Himself a man of very strict notions, in whose eyes all even the most harmless amusements appeared sinful or dangerous, he was determined that his followers must accept his views. Under his rule Geneva, formerly so gay, became like a city of death, where all citizens went about as if in mourning. Such an unnatural condition of affairs could not be permanent. The people soon grew tired of their dictator and of his methods; the authorities of Berne were roused to hostility by his refusal to accept their doctrinal programme or their model religious organisation; the Synod of Lausanne declared against him for a similar reason, and in 1538 he and his principal supporters were driven from the city. Cardinal Sadoleto took occasion to address a stirring appeal to Geneva to return to the old faith, but his appeal fell upon deaf ears. Calvin retired at first to Strassburg, and later he took charge of a parish in France. During the interval he devoted himself to a closer study of the disputed religious questions, and wrote much in favour of the Reformation. It was at this time (1540) that he married the widow of one of the Anabaptist leaders. Meanwhile Geneva was torn by disputes between two factions, the Libertines as they were called, who were opposed to Calvin, and the Guillermins, who clamoured for his return. The latter body gained ground rapidly, and a decree was issued recalling Calvin to Geneva (October 1540). Knowing well that his presence was necessary to restore peace to the city he refused to return unless the conditions imposed by him should be accepted. In the end he went back to Geneva practically as its religious and political dictator (1541).
