EUDOCIA was also the name of several other Roman empresses; the most notable was Eudocia Augusta of Macrembolis, wife of the Emperor Constantine XI., and after his death of Romanus IV. She had sworn to her first husband on his deathbed not to marry again, and had even imprisoned and exiled Romanus, who was suspected of aspiring to the throne. Perceiving, however, that she was not able unaided to avert the invasions which threatened the eastern frontier of her empire, she revoked her oath, married Romanus, and with his assistance dispelled the impending danger. She did not live very happily with her new husband, who was warlike and self-willed, and was ultimately compelled to vacate the throne in favour of her son Michael. She retired to a convent, where she died at an advanced age.
