The Reformed faith took different shapes in different parts of Europe. In France, groups of Christians influenced by Protestant writers (who became known as Huguenots) formed secretly and started underground churches and informal Bible reading groups. Ministers were dispatched from Geneva and other Swiss cities along with a massive outpouring of propaganda which assured the Reformed nature of the French Reformation. Calvin also aided in the creation of the French Confession of Faith in 1559. The French Protestants did gain some notable allies, including Renée of France, daughter of King Louis XII, as well as Queen Jeanne III of Navarre and her son, Henry (who later converted to Roman Catholicism upon ascending the throne of France). The newly formed churches developed a presbyterial system of church government with national and regional synods. The network of synods proved helpful in mobilizing Reformed Christians to military resistance during the French Wars of Religion between Protestants and Catholics from 1562 to 1598. Calvin's successor in Geneva Theodore Beza also argued in his "Right of Magistrates" that armed resistance against tyrannical rulers was justified, which contradicted Calvin's earlier insistence on civil obedience and emboldened Huguenots to fight. The wars of religion left the French Reformed church between one-third and one-half the size of that at which it began with limited freedom to practice their religion, though intermittent conflicts continued. Unlike in the Genevan model and many other early Reformed churches, the Reformed Church in France remained relatively independent of the state.
