Odo III of Burgundy

Odo III (1166 – 6 July 1218) was Duke of Burgundy from 1192. Unlike his father he was a loyal ally of Philip II, fighting King John of England and Emperor Otto IV; at the Battle of Bouvines in 1214 chroniclers record two horses killed beneath him. He led the 1209 Albigensian campaign against the Cathar strongholds after Philip refused to join, and pledged a castle and village to the Templars.

He repudiated his first wife Theresa of Portugal in 1195, and in 1199 married Alice of Vergy, who bore his heir Hugh IV in 1213. He died in 1218.
