The Iberian War, which had been provoked by the uprising of the Iberians against the Persians in 524/5, had been largely indecisive: the Persians swiftly crushed the revolt, but were unable to make any gains in Byzantine territory except for two forts, Scanda and Sarapanis, in Lazica. The Byzantines had recovered from some early reversals to inflict two major defeats on the Persians in 530 at Dara and Satala. In their aftermath, they gained the two border forts of Bolum and Pharangium in Persarmenia, but were in turn defeated at Callinicum in 531. Throughout these conflicts, periods of truce and negotiations were interspersed with campaigns, but these had led to no concrete results.
