Charles, Duke of Calabria

Charles, Duke of Calabria (1298–1328), son of Robert the Wise of Naples, became Duke of Calabria on his father's accession in 1309. After Castruccio Castracani won Altopascio in 1325, Florence elected Charles its signore for ten years in 1326. Then attempting to take Sicily, he sent Walter of Brienne as his deputy.

Charles's arrival checked Castracani, but his harsh taxes led to his recall in 1327, when Emperor Louis IV entered Italy. He died in 1328, before his father. His daughter by Marie of Valois inherited Robert's crown as Queen Joanna I, and a posthumous daughter, Maria, followed.
