Euphrosyne (9th century)

She was a daughter of Byzantine emperor Constantine VI, the last representative of the Isaurian dynasty, and his empress Maria of Amnia.

In January 795, Constantine VI divorced Maria and sent her along with Euphrosyne and her sister Irene to a convent on the island of Prinkipo.

Theodora would go on to restore the veneration of icons in the Empire, forbidden since 815, when Leo V the Armenian restarted the Byzantine Iconoclasm.

After rumours reached Constantinople that Theophilos had been killed in his campaign against Al-Afshin in Anatolia, those senators and senior officials opposed to the Emperor did not trouble themselves to discover if the news were true or not and looked for alternative candidates for the throne.

According to later Arabic and Syriac sources the message read "The Romans who have come have reported that you are killed and they wish to appoint another emperor; come quickly."
