Latin emperor of Constantinople, belonged to that branch of the Courtenay family which was descended from the kings of France. He was chosen to succeed the emperor Henry in 1217, being then in France, where he held the dignity of count of Auxerre. While traversing Epeirus with an army on his way to Constantinople, he was made a prisoner by Theodore, despot of Epeirus, and died in captivity in 1219, having never sat on the throne. We consequently dis miss him, and only mention that his successor was his second son, Robert.
