Theodora married Justinian in 523AD, before his access to the Imperial Throne.

The Empress Theodora in San Vitale
She regularly attended the Imperial Council and presided over it whenever her husband was away. Indirect traces of her influence on Byzantine policies are found in the “Corpus Juris Civilis” the new legal platform promulgated during Justinian reign.She protected women in general, and prostitutes in particular, for whom she edified houses and set a fund for their assistance and redemption.
