This article is about the Byzantine Emperor. There is also an article on Pope Leo VI
Leo VI "the Wise" or "the Philosopher" (Greek: Λέων ΣΤ΄, Leōn VI), (September 19, 866 – May 11, 912) was Byzantine emperor from 886 to 912 during one of the most brilliant periods of the state's history.

Background
One of the first actions of Leo VI after his succession was the reburial of Michael III in Constantinople, which may have contributed to the suspicion that he was Michael's son. Seeking political reconciliation, the new emperor secured the support of the officials in the capital, and surrounded himself with bureaucrats like Stylianos Zoutzes and the eunuch Samonas. His attempts to control the great aristocratic families (e.g., the Phokadai and the Doukai) occasionally led to serious conflicts. Leo also attempted to control the church through his appointments to the patriarchate. He dismissed the Patriarch Photios of Constantinople, who had been his tutor, and replaced him with his own 19-year old brother Stephen in December 886. On Stephen's death in 893, Leo replaced him with Zaoutzes' nominee, Antony II Kaleuas, who died in 901. Leo then promoted his own imperial secretary (mystikos) Nicholas, but replaced him with his spiritual father Euthymios in 907.
Leo completed work on the Basilica, the Greek translation and update of the law code issued by Justinian I, which had been started during the reign of Basil.

Foreign Policy
Leo VI caused a major scandal with his numerous marriages which failed to produce a legitimate heir to the throne. His first wife, whom Basil had forced him to marry, died in 897, and he married Zoe Zaoutzaina, the daughter of his adviser Stylianos Zaoutzes, though she died as well in 899. Upon this marriage Leo created the title of basileopatōr ("father of the emperor") for his father-in-law.
After Zoe's death a third marriage was technically illegal, but he married again, only to have his third wife die in 901. Instead of marrying a fourth time, which would have been an even greater sin than a third marriage (according to the Patriarch Nicholas Mystikos) Leo took as mistress, Zoe Karbonopsina. He married her only after she had given birth to a son in 905, but incurred the opposition of the patriarch. Replacing Nicholas Mystikos with Euthymios, Leo got his marriage recognized by the church, but opened up a conflict within it and allowed new grounds for papal intervention into Byzantine affairs when he sought and obtained papal consent.

Fourth marriage dispute
The future Constantine VII was the illegitimate son born before Leo's uncanonical fourth marriage to Zoe Karbonopsina. To strengthen his son's position as heir, Leo had him crowned as co-emperor on May 15, 908, when he was only two years old. Leo VI died on May 2, 912. He was succeeded by his younger brother Alexander, who had reigned as emperor alongside his father and brother since 879.
