Иоанн II Комнин
The Byzantine Empire and Hungary waged a series of wars against each other between 1127 and 1167. The Byzantine Emperor John II Komnenos routed a Hungarian army at Haram on the Danube (at present-day Bačka Palanka) in 1128. Thereafter he seized and sacked the nearby fortress. A Byzantine army also broke into Hungary at Haram in 1162.
