the siege of trebizond in april 1282 was an unsuccessful siege of trebizond, the capital of the namesake empire, by the georgians under command of david i of imereti. little is known about the attack, but it may have relied on support within the trapezuntine aristocracy, which opposed the rapprochement of emperor john ii of trebizond (reigned 1280–1297) with the palaiologan byzantine court at constantinople. though king david failed to take the city, the georgians occupied several provinces, including greater lazia. john left for trebizond on 25 april 1282 with his new wife, eudokia palaiologina. not long after john arrived home, he was confronted by his half-sister theodora, daughter of manuel i by his georgian wife, rusudan, who apparently deposed him in 1284 to rule for a short time before making a "sudden flight" (in michael panaretos' words) from trebizond; michel kuršanskis suggests he may have taken refuge in tripolis. john was restored to the throne no later than 1285.
