in 1585, the catholics, led by henry of guise, raised an army and forced king henry iii to outlaw protestantism in france. the war that followed, the eighth war, is also known as the "war of the three henrys" and is named after king henry iii, henry of guise, and henry of navarre. even though henry iii and henry of guise were on the same side in 1585, many catholics feared that henry iii secretly wanted henry of navarre to be the next king. in 1588, the supporters of henry of guise, known as "leaguers," chased king henry iii out of paris. in 1589, afraid that henry of guise wanted to take the throne from him, henry iii had him murdered, fled to the protestant army, and joined forces with henry of navarre. charles of mayenne, henry of guise's brother, became the leader of the leaguers.
