Theodora was a 6th-century Byzantine empress who reigned alongside her husband, Justinian I, from 527 until her death in 548. Born in Constantinople to a family of circus workers, she rose from a background in the theater to become a powerful political partner and advisor to the emperor. She played a significant role in imperial governance, including the management of the Nika riots and the support of Monophysite Christians. Recognized as a saint in several traditions, she remains a prominent figure in Byzantine history.
