Robert of Constantinople (d. 1228)

Latin emperor of Constantinople (1221-1228).

The second son of Peter of Courtenay, emperor of Constantinople, and Yolande of Flanders, Robert was crowned emperor in Constantinople (mod. Istanbul, Turkey) on 25 March 1221, after a period of regency following the death of his father (1217). Robert renewed peace with Theodore I Laskaris, emperor of Nicaea, but the planned marriage with Theodore’s daughter Eudokia was not realized. In 1224 the Latins were defeated at Poimanenon by John III Vatatzes, the new emperor of Nicaea, who imposed humiliating peace conditions. Robert, a man inclined to pleasures, generally neglected state affairs, and his reign was disastrous for the Latin Empire. When the barons mutilated the face of the young Frenchwoman he had married in secret, Robert left Constantinople. He died in the Morea, probably in January 1228.
