Prince de Iturbide was the title originally created as Princess of Iturbide on June 22, 1822, by the Mexican Constituent Congress, to be granted to the older sister of Emperor Agustín de Iturbide. Upon the arrival of Maximilian of Habsburg, he again decreed the titles of Prince and Princess of Iturbide for the daughter who was still alive and the two grandchildren of Agustín de Iturbide.
