Mauros

Mauros (; , "black, dark") (fl. 686–711) was a Bulgar leader, one of the chief subordinates and closest supporters of Kuber, a 7th-century Bulgar ruler in Macedonia. After orchestrating a foiled attempt to capture Thessaloniki for Kuber, Mauros remained in the city and joined the ranks of the Byzantine aristocracy. He was bestowed the noble title of patrikios and was deeply involved in the power struggle between Justinian II and Philippikos Bardanes in the beginning of the 8th century. Mauros is the earliest attested leader, styled archon, to be placed by the Byzantine government in charge of a dependent people, in this case the Bulgars and Sermesianoi who had fled to Byzantium.

Bulgar plot to capture Thessaloniki Mauros first appears in the sources in relation to Kuber's plot to conquer Thessaloniki in c. 686–687. From the testaments of contemporaneous historians, it is apparent that Mauros was a well-respected figure among the population ruled by Kuber, which consisted of Bulgars and Sermesianoi (Byzantine refugees from Sirmium on the Sava) who had settled in Macedonia. Bulgarian historian Plamen Pavlov conjectures that Mauros may have been the kavhan (first minister) or ichirgu-boil (general of the highest rank) of Kuber. Regardless of whether he had an official title at all, Mauros was certainly among Kuber's most trusted associates. Prior to his mission in Byzantium, Mauros was polygamous and a . In line with the plan, Mauros was sent by Kuber to Thessaloniki pretending to be a refugee in charge of a group of people fleeing from Kuber. Mauros was not only welcomed inside the city, but also put in charge of all Bulgar and Sermesianoi refugees and given the title of hypatos by Byzantine Emperor Justinian II (r. 685–695, 705–711). Mauros appears to have commanded his own military force, consisting of former subjects of Kuber who were nominally part of the Byzantine army. While many of Thessaloniki's notables were suspicious of Mauros, his significant power enabled him to effectively deal with anyone who was close to uncovering his plot. However, his plan had perhaps been revealed to the Byzantines: the Byzantine navy and its chief admiral Sisinnios arrived in the city, preventing Mauros from undertaking any military activity. When the navy anchored in Thessaloniki, Mauros appeared to fall ill and spent a long time in bed under the surveillance of Sisinnios. While the allegations against Mauros were never proven, he was nonetheless dispatched outside the city along with Sisinnios's men, hoping to attract new refugees from Kuber and the local Slavs. testify to Mauros's elevation to the status of "patrikios and archon of the Sermesianoi and the Bulgaroi". In fact, Mauros appears to have been the first attested case in a long Byzantine tradition of granting rulers of unassimilated but pro-imperial populations the title of archon. Some researchers assert the identification of Kuber's associate with Mauros of the seals; others do not exclude the possibility that the Mauros of the seals was the former's son.

Even as a member of the Byzantine nobility, Mauros made one more attempt to assist Kuber in an anti-Byzantine plot, this time threatening the life of the emperor. However, he was once again unsuccessful. The conspiracy was uncovered by his own son from a Byzantine woman, Mauros was imprisoned in a Constantinople suburb and stripped of his noble titles.

Despite this episode, the next reference to Mauros describes him once again as a patrikios in service of Justinian towards the end of that emperor's second reign in 705–711.

On the way back from Chersonesos, the navy was hit by a horrible storm which claimed thousands of victims, but Mauros survived. Not long after the first expedition, he had to return to Chersonesos because sedition in the city had begun anew, and the newly installed Elias had joined the insurgents. Prior to Mauros's arrival, a naval expedition had failed to crush the uprising and its leaders had been murdered. Assessing the size of the rebellion, Justinian dispatched Mauros in charge of a large force complete with siege engines. Mauros had some success with the siege of the city early on, but the arrival of Khazar support for the insurgents caused Mauros to abandon Justinian and he too joined the ranks of his opponents, led by Philippikos Bardanes.

Justinian apparently sought to intercept the ships of the insurgents at Sinope, on the Black Sea coast of Asia Minor, since he moved to that city. However, he arrived only to see the rebel navy pass Sinope en route to the capital Constantinople, where Philippikos (r. 711–713) was proclaimed emperor. Mauros and Ioannes, another associate of Philippikos, seized him and Tiberios was promptly executed. This is the last mention of Mauros in the sources, and his subsequent fate is unknown.
