Иоанн II Комнин
John Kinnamos wrote of a second campaign by Stephen against the Byzantine Empire. The Hungarian troops, supported by Czech reinforcements under the command of Duke Vaclav of Olomouc, took Braničevo by storm and destroyed its fortress. Emperor John II Komnenos was forced to retreat and sue for peace. Historian Ferenc Makk writes that the resulting peace treaty was signed in October 1129.
