John Kourkouas, also transliterated as Kurkuas or Curcuas, was one of the most important generals of the Byzantine Empire. His success in battles against the Muslim states in the East reversed the course of the centuries-long Arab–Byzantine wars and set the stage for Byzantium's eastern conquests later in the century.

The Byzantine–Bulgarian war of 913–927 was fought between the Bulgarian Empire and the Byzantine Empire for more than a decade. Although the war was provoked by the Byzantine emperor Alexander's decision to discontinue paying an annual tribute to Bulgaria, the military and ideological initiative was held by Simeon I of Bulgaria, who demanded to be recognized as Tsar and made it clear that he aimed to conquer not only Constantinople but the rest of the Byzantine Empire, as well.
