Deposition
During his second reign, Justinian would prove to be merciless in his pursuit of vengeance against supporters of Leontios and Tiberios III. The growing discontent over his harsh rule would lead to further conflict for the throne. In 711, a new revolt started in Cherson under exiled general Bardanes, renamed Philippikos, and Busir lend his support to the rebels.
Justinian was absent in Armenia when the revolt started and was unable to return to Constantinople in time to defend it.He was arrested and executed outside the city in December 711, his head being sent to Bardanes as a trophy. On hearing the news of his death Anastasia, Justinian's mother, took his six-year-old son and co-emperor, Tiberios, to sanctuary at St. Mary's Church in Blachernae, but was pursued by Philippikos' henchmen, who dragged the child from the altar and, once outside the church, murdered him, thus eradicating the line of Heraclius.
Whether Theodora was still alive during the events remains unclear. Theophanes and Nikephoros make no mention of her when recounting the deposition. Joannes Zonaras presumed her to be already deceased. Zonaras was writing four centuries after the events and the factual accuracy of his statement is debatable. Unlike other Empresses, there is no tomb mentioned for her and the year and manner of her death remains unknown.
