French Wars of Religion
The Royal-Protestant army defeated the Leaguers at the Battle of Senlis and surrounded Paris.  Before they could capture the city, King Henry III was killed by a Leaguer but named Henry of Navarre as his heir.  Henry of Navarre, now Henry IV of France, defeated Leaguer armies at the Battle of Arques (1589) and the Battle of Ivry (1590) but could not completely defeat the Leaguers on the battlefield.  In 1593, King Henry IV converted to Catholicism.
