Trebizond was greatly affected by two events over the following centuries: in the civil war between Septimius Severus and Pescennius Niger, the city suffered for its support of the latter, and in 257 the city was pillaged by the Goths, despite reportedly being defended by "10,000 above its usual garrison", and being defended by two bands of walls.
