Theodora Komnene

Theodora Megale Komnene (Greek: Θεοδώρα Μεγάλη Κομνηνή, Theodōra Megalē Komnēnē), (before 1253– after 1285), Empress of Trebizond from 1284 to 1285. She was a daughter of Emperor Manuel I of Trebizond by his second wife, Rusudan, a Georgian princess.

In 1284, with help of Georgian King of Imereti, David VI Narin she managed to seize the crown from her half-brother, Emperor John II. Shortly afterwards she was defeated and John regained his throne, but she had managed reign long enough to have minted her own coins. Either before or after her short reign, Theodora was a nun.

b) THEODORA Komnene (-after [1285]). The Chronicle of Michael Panaretos records "the attack, raid and sudden flight of the lady Theodora Komnene, the first daughter of the lord Manuel the Grand Komnenos by Russadan from Iberia", dated to [1283/85] from the context[29]. She succeeded her brother in [1284/85] as THEODORA Empress in Trebizond. The existence of 36 specimens of coins struck during her reign confirms that this laconic passage in Michael Panaretos indicates that Theodora ruled as empress for a brief period, although the circumstances of her succession and flight are unknown] ref: http://fmg.ac/Projects/MedLands/TREBIZOND.htm#AlexiosITrebizondB
