Odo, Count of Nevers

Odo of Burgundy, in French Eudes de Bourgogne or Eudes de Nevers (1230 – 4 August 1266), was the Count of Nevers, Auxerre and Tonnerre and son of Hugh IV, Duke of Burgundy and Yolande of Dreux.

In 1265, Odo became one of the last European barons to lead a crusading force to the Holy Land. Among his fifty knights was Erard of Valery. He defended Acre when Sultan Baybars I harassed it on 1 June 1266 in advance of his besieging Safad. He died at Acre on 7 August 1266 and was buried in the church of Saint Nicholas. He left all his wealth to pay his followers and to endow hospitals and religious institutions. He was described by the Templar of Tyre as a "holy man", and his tomb attracted veneration. Within a year of his death, the poet Rutebeuf wrote a Complainte du comte Eudes de Nevers, a lament for a valiant knight and also for the city that lost its defender.

Burgundy passed to Odo's brother, Robert.

Marriage and children Odo married Maud of Dampierre and they had: Yolande, Countess of Nevers (1247–1280), married (1) John Tristan, Count of Valois, and (2) Count Robert III of Flanders Margaret, Countess of Tonnerre (1250–1308), married King Charles I of Naples Adelaide, Countess of Auxerre (1251–1290), married John I of Chalon, Lord of Rochefort Jeanne (1253–1271), died young
