persecuted the old, pre-Protestant movement of Waldensians in southeastern France. Francis initially protected the Huguenot dissidents from Parlementary measures seeking to exterminate them. After the 1534 Affair of the Placards, however, he distanced himself from Huguenots and their protection. Huguenot numbers grew rapidly between 1555 and 1561, chiefly amongst nobles and city dwellers. During this time, their opponents first dubbed the Protestants Huguenots; but they called themselves , or "Reformed". They organised their first national synod in 1558 in Paris. By 1562, the estimated number of Huguenots peaked at approximately two million, concentrated mainly in the western, southern, and some central parts of France, compared to approximately sixteen million Catholics during the same period. Persecution diminished the number of Huguenots who remained in France. Wars of religion As the Huguenots gained influence and displayed their faith more openly, Roman Catholic hostility towards them grew, even though the French crown offered increasingly liberal political concessions and edicts of toleration. Following the accidental death of Henry II in 1559, his son succeeded as King Francis II along with his wife, the Queen Consort, also known as Mary, Queen of Scots. During the eighteen months of the reign of Francis II, Mary encouraged a policy of rounding up French Huguenots on charges of heresy and putting them in front of Catholic judges, and employing torture and burning as punishments for dissenters. Mary returned to Scotland a widow, in the summer of 1561. In 1561, the Edict of Orléans declared an end to the persecution, and the Edict of Saint-Germain of January 1562 formally recognised the Huguenots for the first time. However, these measures disguised the growing tensions between Protestants and Catholics. Civil wars These tensions spurred eight civil wars, interrupted by periods of relative calm, between 1562 and 1598. With each break in peace, the Huguenots' trust in the Catholic throne diminished, and the violence became more severe, and Protestant demands became grander, until a lasting cessation of open hostility finally occurred in 1598. The wars gradually took on a dynastic character, developing into an extended feud between the Houses of Bourbon and Guise, both of which—in addition to holding rival religious views—staked a claim to the French throne. The crown, occupied by the House of Valois, generally supported the Catholic side, but on occasion switched over to the Protestant cause when politically expedient. The French Wars of Religion began with the Massacre
