Catholic League (French)

The Catholic League of France (French: La Ligue catholique), sometimes referred to by contemporary (and modern) Catholics as the Holy League (La Sainte Ligue), was a major participant in the French Wars of Religion. Formed by Henry I, Duke of Guise, in 1576, the League intended the eradication of Protestants—mainly Calvinists or Huguenots—out of Catholic France during the Protestant Reformation, as well as the replacement of King Henry III.

Pope Sixtus V, Philip II of Spain, and the Jesuits were all supporters of this Catholic party.

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 (the primary branch of Protestantism in France) 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.
