Since 1562, there had been a a series of wars in France which were mostly fought between Catholics and Protestants, and sometimes with more than one groups of Catholics fighting each other. In 1584, Henry became the heir to the throne of France. Most people in France were Catholics, and many of them did not want a Protestant king. This led to the War of the Three Henrys between Henry of Navarre, the existing Catholic king Henry III and Catholic League leader Henry, Duke of Guise. Although both Henry III and Guise were Catholics, they did not get on with each other. Guise was murdered in 1588 and Henry III was murdered the following year.
