Campanian
The Campanian is, in the ICS' geologic timescale, the fifth of six ages of the Late Cretaceous epoch (or, in chronostratigraphy: the fifth of six stages in the Upper Cretaceous series). The Campanian spans the time from 83.6 ± 0.7 Ma to 72.1 ± 0.6 Ma (million years ago). It is preceded by the Santonian and it is followed by the Maastrichtian.

In 1281, with the advent of the Sicilian Vespers, the kingdom split in half. The Angevin Kingdom of Naples included the southern part of the Italian peninsula, while the island of Sicily became the Aragonese Kingdom of Sicily. The wars continued until the peace of Caltabellotta in 1302, which saw Frederick III recognised as king of the Isle of Sicily, while Charles II was recognised as the king of Naples by Pope Boniface VIII. Despite the split, Naples grew in importance, attracting Pisan and Genoese merchants, Tuscan bankers, and with them some of the most championed Renaissance artists of the time, such as Boccaccio, Petrarch and Giotto. Alfonso I conquered Naples after his victory against the last Angevin king, René, and Naples was unified for a brief period with Sicily again.
