Answer
Theodora was chosen in a bride-show for the young Theophilos by Euphrosyne, the Empress and mother of Theophilos. Theodora was a prostitute, but Euphrosyne was impressed with her beauty and intelligence. Theodora was also a skilled actress, and she was able to convince Theophilos that she was a virgin. Theophilos married Theodora in 821, and they ruled together until Theodora's death in 856.
