settled down in the Byzantine Empire after the death of Emperor Frederick. It is known that Géza took a Byzantine noblewoman (possibly from the ruling Angelos dynasty) as wife between 1190 and 1191. According to a Greek codex kept in the Saint Catherine's Monastery, translated by historian Szabolcs de Vajay, Géza adopted the name Ioannes (John) in the Byzantine Empire. Géza was the uncle of Empress Margaret, the consort of Emperor Isaac II Angelos. It is possible that Géza integrated into the Byzantine elite through her assistance and financial support. His sons – one of them, Géza–Alexios is known by name – first appeared in contemporary sources in 1210, it is plausible that Géza had died by then. In that year, a group of discontented Hungarian lords during the conspiracy (1209–10) offered the crown to them against their cousin, the ruling monarch Andrew II of Hungary; they lived in "Greek land". However, their envoys were captured by Domald of Sidraga in Split in 1210. Years later, when Andrew II decided to return to Hungary from the Fifth Crusade in early 1218, the troops of Géza's sons attacked his army when he stayed in Nicaea (now İznik, Turkey).
