In 580, Hormizd IV abolished the Caucasian Iberian monarchy, and turned Iberia into a Persian province ruled by a "marzpan" (governor). During the 580s, the war continued inconclusively with victories on both sides. In 582, Maurice won a battle at Constantia over Adarmahan and Tamkhusro, who was killed, but the Roman general did not follow up his victory; he had to hurry to Constantinople to pursue his imperial ambitions. Another Roman victory at Solachon in 586 likewise failed to break the stalemate.
