Székesfehérvár, known colloquially as Fehérvár, is a city in central Hungary, and the country's ninth-largest city. It is the regional capital of Central Transdanubia, and the centre of Fejér County and Székesfehérvár District. The area is an important rail and road junction between Lake Balaton and Lake Velence.

Géza, also Gejza, was Grand Prince of the Hungarians from the early 970s. He was the son of Grand Prince Taksony and his Oriental—Khazar, Pecheneg or Volga Bulgarian—wife. He married Sarolt, a daughter of an Eastern Orthodox Hungarian chieftain. After ascending the throne, Géza made peace with the Holy Roman Empire. Within Hungary, he consolidated his authority with extreme cruelty, according to the unanimous narration of nearly contemporaneous sources. He was the first Hungarian monarch to support Christian missionaries from Western Europe. Although he was baptised, his Christian faith remained shallow and he continued to perform acts of pagan worship. He was succeeded by his son Stephen, who was crowned the first King of Hungary in 1000 or 1001.
