Guy II de la Roche

Guy II de la Roche (1280 – 5 October 1308) was the Duke of Athens from 1287, the last duke of his family. He succeeded as a minor on the death of his father, William I, at a time when the duchy of Athens had exceeded the Principality of Achaea in wealth, power, and importance.

Guy was originally under the tutorship and regency of his mother, Helena Angelina Comnena, who was forced to make submission to Isabella of Villehardouin in December 1289. In 1291, she married her second husband, Hugh of Brienne, and he became bailiff of the duchy. Guy reached his majority in 1296 and did homage to Isabella and her husband, Florent of Hainaut. In 1299, Guy was engaged to Matilda, daughter of Isabella and Florent. Charles objected, as his permission had not been sought, but Pope Boniface VIII intervened on the young couple's behalf.

When Guy did homage to Isabella's second husband, Philip of Savoy, in 1301, he took his troops with him and entered Thessaly to defend his cousin John II Angelus Comnenus against the invasion of the despot of Epirus, Thomas I Comnenus Ducas, and his mother, Anna Cantacuzenus. Joined by Nicholas III of St Omer, lord of Thebes, he repulsed the Epirotes and later invaded Greek territoy as far as Thessalonica, where they were convinced to turn back by the empress Eirene of Montferrat.

In 1307, Guy was made bailiff of Achaea by its new prince, Philip I of Taranto. He governed well, but for barely a year. He died young, but respected and renowned for his chivalry and manners, typical of the Frankish courts kept in Greece. He was buried in Daphne alongside his ancestors. He left no heirs and the De la Roche line of dukes came to an end; Athens was disputed among rival claimants until the parliament of the duchy elected Walter V of Brienne.
