Catherine I of Courtenay

Catherine of Courtenay (1274–1307) was the heiress of Philip of Courtenay, titular Latin emperor of Constantinople. On her father's death in 1283 she inherited his claim to the Latin Empire, lost to the Greeks in 1261, and was recognized as empress.

After several failed betrothals she married Charles of Valois in February 1301, who then held the imperial title in her right. She died in Paris in 1307, leaving her claim to her daughter Catherine of Valois-Courtenay.
