, which had been conquered in the 820s by
Andalusian exiles. The expedition at first went well, as the Byzantine army landed and took control over most of the island, confining the Andalusians to their capital,
Chandax. At this juncture, Theoktistos heard a rumour that in his absence, Theodora intended to raise her brother Bardas to the imperial throne. He hastily abandoned the army under Niketiates and returned to Constantinople, only to find the rumours false. Once in Constantinople, news arrived of an invasion of

by
Umar al-Aqta, emir of
Melitene. Theoktistos was sent at the head of an army to confront him, but the resulting
Battle of Mauropotamos ended in a Byzantine defeat. At the same time, the expeditionary corps left in Crete was defeated and almost annihilated by the Andalusians, who killed Niketiates.
Despite his personal involvement in these military disasters, Theoktistos was able to use them to sideline his competitors: Bardas was blamed for the desertions that plagued the Byzantines at Mauropotamos and exiled from Constantinople, while the ''magistros'' Manuel was slandered and forced to retire. With Niketiates dead, Theoktistos was now the undisputed head of the regency, a position described by the Byzantine chroniclers, like
Symeon Logothetes and
Georgios Monachos, as "''
paradynasteuon'' of the ''
Augusta''".
Theoktistos continued the persecution of the
Paulicians, which had been initiated by Theodora in 843. Many fled to Arab territory, where with Umar al-Aqta's aid they established a state of their own at
Tephrike under their leader
Karbeas. Theoktistos concluded a truce with the

Constantine-Cyril, whom he first met , helping him to acquire a good education and later to find a post as ''
chartophylax'' in the patriarchal library, after Constantine rejected an offer of becoming a provincial ''strategos''. Theoktistos' sponsorship of men like Constantine and
Leo the Mathematician contributed to the revival of secular learning in Byzantium. Theoktistos was also engaged in building activity, erecting new structures in the Apsis near the

Downfall and death
In 855, Michael III turned fifteen and thus came nominally of age. His mother and Theoktistos both underestimated the young emperor's desire to free himself from their custodianship, and antagonized him further when they arranged a
bride show and selected
Eudokia Dekapolitissa as his bride, disregarding Michael's attachment to his mistress,
Eudokia Ingerina. Theodora's brother Bardas was able to use Michael's resentment for the high-handed manner in which he was treated and began to turn him against the regency. With Michael's backing, Bardas was allowed to return to the capital, and on 20 November 855, Theoktistos was murdered. Theodora was compelled to retire to a monastery a few months later, bringing the regency officially to an end.
