Toynbee "Carlo_1, summarized entry"
Charles I, king of Naples and Sicily, count of Anjou and Provence, seventh son of Louis VIII of France and Blanche of Castile, and brother of St. Louis; he was born in 1226; in 1246 he married Beatrice, youngest daughter of Count Raymond Berenger IV of Provence, in whose right he became count of Provence; after the death of Beatrice in 1267, he married Margaret of Burgundy, daughter of Eudes, duke of Burgundy, in 1268; and in 1266, after the defeat of Manfred at Benevento, he became king of Naples and Sicily; he died Jan. 7, 1284/5.

D. places Charles in the valley of flowers in Ante-Purgatory among the princes whose worldly cares caused them to put off repentance until the last moment; he is seated beside Peter III of Aragon; Sordello, who points him out, refers to him as colui dal maschio naso, [Purg. vii. 113]; and says that he (il seme) is as superior to his son Charles II (la pianta), as Peter III of Aragon is to him (Charles I) ([Purg. vii. 127-129]); he is mentioned in connextion with Pope Nicholas III, who was his enemy, [Inf. xix. 99]; his victories at Ceprano (where Manfred was defeated in 1266) and at Tagliacozzo (where Conradin was defeated in 1268) are alluded to, [Inf. xxviii. 16-17]; Oderisi (in Circle I of Purgatory) mentions him in connexion with Provenzano Salvani, whose friend (taken prisoner at Tagliacozzo) he held to ransom, [Purg. xi. 136-137]; Hugh Capet (in Circle V of Purgatory) speaks of la gran dota provenzale, the wealth added to the house of Capet by the marriage of Charles I to Beatrice, [Purg. xx. 61]; then Hugh Capet speaks of his coming into Italy, and charges him with the murder of Conradin and of Thomas Aquinas, [Purg. xx. 67-69] his grandson Charles Martel (in the Heaven of Venus) speaks of him (or, as some think, of his son, C. M.'s father, Charles II) as the ancestor in whose right his own descendants ought to have been on the throne of Sicily, [Par. viii. 67-72].
