Othon de la Roche

Otto or Othon de la Roche (died 1234) was a Burgundian nobleman from the castle of La Roche-sur-l'Ognon, in the Franche-Comté commune of Rigney, Doubs. He joined the Fourth Crusade in 1204 and became the first Duke of Athens.

He took the title of megaskyr or grand seignior in Athens. He held his Greek possessions from the King of Thessalonica. He fortified the Acropolis. In 1208, he took the title of duke.

In May 1209, the Latin emperor Baldwin I called his first of two parliaments at Ravennika and Otto and his close ally Geoffrey I of Villehardouin made an appearance to demonstrate their loyalty to the emperor. On 2 May 1210, at the second parliament, the two barons ratified the pact between church and state, but he did little to effect it. He was accused of treating the Greek priests as serfs, since many of them were former serfs raised to their clerical status by Greek prelates desiring to lift the heavy burden the Franks could impose with their corvées on the local populace. Pope Honorius III excommunicated him and put his lands under interdict, as he did to Geoffrey for like disobedience to the pact. Circa 1223, Otto made a treaty with the pope by which he returned church lands, but kept church furnishings at the cost of an annual indemnity. A quota was also placed on the number priests proportional to the population of the community.

With Geoffrey, Otto embarked on a series of military adventures to consolidate mainland Greece. Together they took Acrocorinth (1209), Argos (1210), and Nauplia (1211). In compensation, he received two lordships in the Argolid: Argos and Damala. After the Italian crusaders Albertino and Rolandino of Canossa returned, their fief of Thebes was divided between Geoffrey and Otto. The city itself became Otto's capital and the economic centre of his domains, due to its silk industry. He built a square tower, destroyed in the late nineteenth century, on the propylaea there and gave the city as a lordship to his nephew Guy. Athens itself remained Otto's residence. There he lived in his castle atop the Acropolis, having converted the Parthenon into the Cathedral of Our Lady.

Otto established Cistercians from Bellevaux at Daphne.

In 1225, he resigned the Duchy of Athens to his nephew and returned home to Burgundy with his wife.
