Maria of Amnia was the first consort of Constantine VI of the Byzantine Empire.
Background
She was granddaughter of Saint Philaretos, a magnate from the Armeniakon Theme known for his charitable activities, a relation mentioned in his Hagiography. The name of her father is unknown and her mother has been identified as Hypatia by Christian Settipani. Maria was born in Amnia, Paphlagonia.
Constantine was previously betrothed to Rotrude, daughter of Charlemagne and Hildegard, but Irene had called off the engagement.
Career
In 788, Maria was one of thirteen candidates in the earliest recorded bride-show. Maria was the granddaughter of Saint Philaretos. Maria was chosen primarily by Constantine and Staurakios, a eunuch who served as the logothetes tou dromou, were also reportedly involved in the presentation of the candidates.
However whether they influenced the choice is unstated.
The marriage took place in November, 788. The marriage was recorded in the chronicle of Theophanes the Confessor.
The marriage lasted for about six years and resulted in two daughters. Theophanes attributed the deterioration of the marriage to the machinations of The lack of a male heir following six years of marriage could also be one of the reasons.
In 794, Constantine had found a mistress in the person of Theodote, a kubikularia (Lady-in-waiting) of his mother.
In January, 795, Constantine divorced Maria. In September, 795, Constantine and Theodote were wed. The remarriage while Maria was still alive was seen as an attempt for legalization of adultery.
The legality of the second marriage sparked a religious controversy, the so-called "Moechian Controversy" (from the Greek moichos, "adulterer").
However Maria is not recorded as involved with any of the conflicts of the time. She remained a nun for the rest of her life.
She is last mentioned c. 823. Her daughter Euphrosyne was taken from their convent to marry Michael II (reigned 820 – 829).
She protested the decision to no effect.
Her protestation is mentioned in the correspondence of Theodore the Studite. The year of her death is not known.
