Treaty of Joinville

The Treaty of Joinville was signed in secret in December 31, 1584 by the French Catholic League, led by France's first family of Catholic nobles, the Guises, and Habsburg Spain. In this treaty, Philip II, King of Spain, agreed to finance the Catholic League. The aim of the treaty was to form a Catholic alliance against Protestant forces, notably Elizabeth I of England, in response to the potential succession to the French throne of Henry III of Navarre, at this point a Protestant.
