Iberian War participant Byzantine Empire
The Iberian War was fought from 526 to 532 between the Byzantine Empire and the Sasanian Empire over the eastern Georgian kingdom of Iberia—a Sasanian client state that defected to the Byzantines. Conflict erupted among tensions over tribute and the spice trade.
The Sasanians maintained the upper hand until 530 but the Byzantines recovered their position in battles at Dara and Satala while their Ghassanid allies defeated the Sasanian-aligned Lakhmids. A Sasanian victory at Callinicum in 531 continued the war for another year until the empires signed the "Perpetual Peace".
