His father, Louis I of Anjouthe founder of the House of Valois-Anjouwas a younger son of King John II of France and the adopted son of Queen Joanna I of Naples.
When his father died during a military campaign in Naples in 1384, Louis II was still a child.
He inherited Anjou from his father, but his mother, Marie of Blois, could not convince his uncles, John, Duke of Berry and Philip II, Duke of Burgundy, to continue her husband's war for Naples.
The Provençal nobles and towns refused to acknowledge Louis II as their lawful ruler, but Marie of Blois persuaded them one after another to swear fealty to him between 1385 and 1387.
His cousin, King Charles VI of France decided to support Louis II's bid for Naples in 1389.
After Antipope Clement VII crowned him king in Avignon on 1 November 1389, Louis II moved to Naples.
His troops could not occupy the whole kingdom, thus it was practically divided between Louis II and his opponent, Ladislaus of Naples.
The conflict between Clement VII's successor, Antipope Benedict XIII, and France weakened Louis' position and Ladislaus forced him to leave Naples for Provence in 1399.
