Byzantine Empire Empress Irene

Struck after AD 797, when Irene had had her son Constantine VI deposed and murdered, this solidus depicts Irene on both the obverse and reverse, and marks a distinct shift from the types of her predecessors. Gone is the cross-on-steps reverse type, or figures of deceased members of the dynasty, to be replaced by two facing busts of Irene. Here we have Irene proclaiming herself Empress and sole ruler in the most public way possible. However, after just five years on the throne she herself was deposed and replaced by her Minister of Finance, Nicephorus, and thus ended the first period in the history of the empire during which the throne was occupied by a woman exercising power in her own right.

Beginning during the time she ruled as regent for her son Irene severely depleted the state treasuries with her policy of reducing taxation and making generous gifts to buy popularity, leaving the empire weak and unable to offer effective resistance to foreign aggressors. Having had to accept terms from the Arab Caliphs both in 792 and 798 in order to protect the fragile security, and being harried by the Bulgarians simultaneously, Irene was powerless to stop the formation of a new empire in the west under Charlemagne of the realm, who in AD 800 was crowned in Rome by Pope Leo III as Holy Roman Emperor due to his belief that the Imperial position was vacant, as it could not be filled by a woman.
