Confraternities and leagues were established by French Catholics to counter the growing power of the Lutherans, Calvinists and members of the Reformed Church of France. The Protestant Calvinists at that time dominated much of the French nobility, leading to active persecution of Catholics in some regions. Under the leadership of Henry I, Duke of Guise, the Catholic confraternities and leagues were united as the Catholic League. Guise used the League not only to defend the Catholic cause but also as a political tool in an attempt to usurp the French throne. The Catholic League aimed to preempt any seizure of power by the Huguenots and to protect French Catholics' right to worship. The Catholic League's cause was fueled by the doctrine Extra Ecclesiam Nulla Salus. Catholic Leaguers saw their fight against Calvinism as a Crusade against heresy. The League's pamphleteers also blamed any natural disaster that occurred in France at the time as God's way of punishing France for tolerating the existence of the Calvinist heresy. After a series of bloody clashes, the French Wars of Religion, between Catholics and Protestants, the Catholic League formed in an attempt to break the power of the Calvinist gentry once and for all. The Catholic League saw the French throne under Henry III as too conciliatory towards the Huguenots. The League, similar to hardline Calvinists, disapproved of Henry III's attempts to mediate any coexistence between the Huguenots and Catholics. The Catholic League also saw moderate French Catholics, known as Politiques, as a serious threat. The Politiques were tired of the many tit for tat killings and were willing to negotiate peaceful coexistence rather than escalating the war.
History of the League
The League immediately began to exert pressure on Henry III of France. Faced with this mounting opposition he canceled the Peace of La Rochelle, re-criminalizing Protestantism and beginning a new chapter in the French Wars of Religion. However, Henry also saw the danger posed by the Duke of Guise, who was gaining more and more power. In the Day of the Barricades, King Henry III was forced to flee Paris, which resulted in Henry, Duke of Guise becoming the de facto ruler of France. Afraid of being deposed and assassinated, the King decided to strike first. On December 23, 1588, Henry III's guardsmen assassinated the Duke and his brother, Louis II and the Duke's son was imprisoned in the Bastille. However, this move did little to consolidate the King's power and enraged both the surviving Guises and their followers. As a result, the King fled Paris and joined forces with Henry of Navarre, the throne's Calvinist heir presumptive. Both the King and Henry of Navarre began building an army with which to besiege Paris. On August 1, 1589, as the two Henrys besieged the city and prepared for their final assault, Jacques Clément, a Dominicanlay brother with ties to the League, successfully infiltrated the King's entourage, dressed as a priest, and assassinated him. This was retaliation for the killing of the Duke of Guise and his brother. As he lay dying, the King begged Henry of Navarre to convert to Catholicism, calling it the only way to prevent further bloodshed. However, the King's death threw the army into disarray and Henry of Navarre was forced to lift the siege. vanquishing the Lernaean Hydra, by Toussaint Dubreuil, circa 1600. Louvre Museum. Although Henry of Navarre was now the legitimate King of France, the League's armies were so strong that he was unable to capture Paris and was forced to retreat south. Using arms and military advisors provided by Elizabeth I of England, he achieved several military victories. However, he was unable to overcome the superior forces of the League, which commanded the loyalty of most Frenchmen and had the support of Philip II of Spain. The League then attempted to declare the Cardinal of Bourbon, Henry's uncle, as king Charles X of France on November 21, 1589, but his status as a prisoner of Henry of Navarre and his death in May 1590 removed all legitimacy from this gesture. Furthermore, the Cardinal refused to usurp the throne and supported his nephew, although to little avail. Unable to provide a viable candidate for the French throne, the League's position weakened, but remained strong enough to keep Henry from besieging Paris. Finally, in a bid to peacefully end the war, Henry of Navarre was received into the Church on July 25, 1593 and was recognized as King Henry IV on February 27, 1594. He is purported to have said later, "Paris is well worth a Mass," though some scholars question the veracity of this quotation. Under the rule of King Henry IV, the Edict of Nantes was passed, granting religious toleration and limited autonomy to the Huguenots and ensuring a lasting peace for France. Moreover, the Catholic League now lacked the threat of a Calvinist king and gradually disintegrated.
Assessment
Historian Mack Holt argues that historians have sometimes over-emphasised the political role of the League at the expense of its religious and devotional character:
