EUDOCIA MACREMBOLITISSA (c. 1021-1096), daugh ter of John Macrembolites, was the wife of the Byzantine emperor Constantine X. After his death (1067), to protect her infant son and to enable the menace of the Turks on the eastern frontier to be met, she married Romanus Diogenes and made him regent. On his capture in 1071 she vacated the throne in favour of her son and retired to a convent. The 'Iwvia ascribed to her really dates from the 16th century.
