Carlo II was born in 1254, the eldest son of his father Carlo I and his first wife Beatrice of Provence. Carlo II was the only heir of Carlo I (his brother Philip of Sicily died in 1277). Carlo I arranged Carlo II as the heir of his huge kingdom very early. When Carlo II was born, Carlo I had ruled the Kingdom of Provence, Foukalchiya, Anjou, Mann and Naples. In the 1270s, his father also claimed to be the King of Albania (because he had conquered the east bank of the Ionian Sea) and the King of Jerusalem, and also inherited the Achaia principality in Peloponnese. Carlo II's mother died in 1267, but his father intended to rule the whole kingdom intact when he died, thus depriving Carlo II of the inheritance right of his mother. In 1272, his father handed over the kingdom of Sereno in Sicily to Carlo II, and in 1279, he granted Carlo II the regent of Provence and Fokalchiya.
In 1269, Karol I arranged a double marriage union with Istvan V of Hungary. Maria, the 12-year-old daughter of Ishtwan V, was engaged to Carlo II, who was 15 years old. Isabel, the 4-year-old sister of Carlo II, was engaged to Laszlo IV, Ishtwan V's 7-year-old son. They married in 1270. Carlo II was seriously ill at the end of 1271. In order to encourage the prayer for his recovery, his father, Carlo I, donated the wax carvings of Carlo II to pilgrims all over the country to churches where he often went. After the recovery of Carlo II, Carlo I made a pilgrimage to the Saint Nicholas Temple in Bali, and sent the gifts to the Holy Mary's Shrine in Rocamador. Carlo II and his brother Philip of Sicily were knighted on Pentecost in 1272 together with 100 other young nobles from France and Italy. At this time, Karol I handed over the kingdom of Prince Sareno to Karol II (Prince Sareno was the symbol of the heir to the throne when the Otwell family ruled the kingdom of Sicily), but the king said that Karol II could not claim other parts of the kingdom, but should avoid Karol II from claiming Provence.
On June 5, 1284, Carlo was captured in the war against Aragon. Because the Sicilians wanted him to pay for his life, Constance, the wife of Pedro I, imprisoned him in the castle of Chefalu for protection. On January 7, 1285, his father died in Foja, so he had to appoint Roberto of Artua as regent, and temporarily rule the country with Carlo's eldest son until he was released to return home. In 1288, Carlo was finally released after paying the ransom, and was crowned king by Pope Nicholas IV in Leti in 1289. Later, Carlo II tried to retake Sicily from Aragorn, but failed. He finally recognized Federico II, the third son of Pedro I, as the king of Sicily, and married his daughter to him. Carlo Matt, the eldest son of Carlo II, died first. According to the inheritance law, Carlo Robel, the son of Carlo Matt, will become the successor, but Carlo II prefers the third son Roberto, hoping that he will inherit the throne, so he encouraged Carlo Robel to seize the Hungarian throne by virtue of his grandmother's Hungarian blood, and took the opportunity to deprive Carlo Robel and his descendants of their inheritance rights to Naples. On May 5, 1309, Carlo II died in Naples and Roberto succeeded him. [1]
