  Research Notes:

The Chronicon Varadiense names "dux Geisa, pater B. Stephani, secundus…Michael dux" as the two sons of "Toxin". The Kronika Węgiersko-Polska names "Geyzan, Mychlemum et caluum Ladislaum" as the three sons of "Thoxon". The Gestis Hungarorum Liber names "Geysam, quantum ducem Hungarie" as son of "dux Tocsun".

He succeeded his father in [970] as Prince of Hungary. He sent ambassadors to the court of Emperor Otto I, with whom he established friendly relations. Géza was baptised in 974 as ISTVÁN [Stephen] by priests sent by Pilgrim Bishop of Passau, although he appears to have adopted Christianity more for political expediency than religious conviction as he never renounced his pagan beliefs entirely, declaring himself, according to Macartney, "rich enough to afford two gods".... He continued to use his pre-baptismal name Géza. He centralised Magyar government, based at Esztergom, where his bodyguard consisted of Bavarian knights. The alliance with Bavaria was confirmed after the accession in 985 of Duke Heinrich II, and sealed by the marriage of Duke Heinrich's daughter to Géza's heir in 996. Thietmar names "Deuvix" as father of King István, describing him as "very cruel…when becoming a Christian…he turned his rage against his reluctant subjects [and] sacrificed both to the omnipotent God and to various false gods. When reproached by his priest for doing so, he maintained that the practice had brought him great wealth and power".

The Chronicon Posoniense records the death in 998 of "Geyza princeps Ungarorum". ¹
