When was the sister of Theodora Porphyrogenita died who was reigned as Byzantine Empress alongside her sister?
Zoë Porphyrogenita Zoë ( "life" ] ; 978 – June 1050) reigned as Byzantine Empress alongside her sister Theodora from April 19 to June 11, 1042. She was also enthroned as the Empress Consort to a series of co-rulers beginning with Romanos III in 1028 until her death in 1050 while married to Constantine IX.
Michael III Michael III (Greek: Μιχαήλ Γʹ , "Mikhaēl III"; January 19, 840 – September 23/24, 867) was Byzantine Emperor from 842 to 867. Michael III was the third and traditionally last member of the Amorian (or Phrygian) dynasty. He was given the disparaging epithet "the Drunkard" (ὁ Μέθυσος ) by the hostile historians of the succeeding Macedonian dynasty, but modern historical research has rehabilitated his reputation to some extent, demonstrating the vital role his reign played in the resurgence of Byzantine power in the 9th century.
