The Vardariotai (Greek: Βαρδαριῶται), sometimes Anglicized as Vardariots, were an ethnic and territorial group (probably originally of Magyar origin) in the later Byzantine Empire, which provided a palace guard regiment during the 12th and 13th centuries.
The exact origin and nature of the Vardariotai is uncertain. The name first appears in the 10th century, when a bishopric of the "Vardariotai or Tourkoi" is mentioned as subject to the diocese of Thessalonica. The mid-14th century writer Pseudo-Kodinos calls them "Persians" by race (a typical Byzantine anachronism for "Turks"), and recalls that they were settled in the Vardar river valley by an unnamed Byzantine emperor of old. In both cases, however, "Turks" probably implies the Magyars, who were called "Tourkoi" by the Byzantines in the 10th–11th centuries. Hence it seems that the Vardariotai were Magyars resettled in Macedonia in the 10th century, and that they had become Christianized by the century's end.
By the 12th century, the Vardariotai, their Magyar identity by now much diluted, were being recruited into the Byzantine army, and, at the latest during the latter part of the reign of Emperor Manuel I Komnenos (r. 1143–1180), they were formed into a distinct palace guard regiment. Their functions, however, at least in the Palaiologan period, appear to have been more those of a police force than a military unit: Pseudo-Kodinos lists them not with the guards but with the unarmed palace personnel, and states that their duty was "to keep people orderly" during ceremonies. Unlike the armed members of the Varangian Guard and the Paramonai regiment, they were equipped only with a whip (the manglabion) and a staff (the dekanikion). Kodinos also records that they wore distinctive red uniforms and a "Persian" hat called angouroton ("cucumber-shaped"), and that the whip, hanging at their belt, was their symbol. This latter reference has led to the hypothesis that the Vardariotai were the replacement of the older Manglabites guards corps. They were commanded by a primikerios, first attested in the year 1166. The 13th-century historian George Akropolites further states that the Vardariotai accompanied the Byzantine emperor to his military camp whilst on campaign.
It is unclear whether and how the vardarioi, administrative officials of Thessalonica in the 10th–11th centuries known through their seals, are related to the Vardariotai.
