The date of his baptism is unknown.
He was the only son of Grand Prince Géza and his wife, Sarolt, who was descended from the prominent family of the "gyulas".

He married Gisela of Bavaria, a scion of the imperial Ottonian dynasty.
After succeeding his father in 997, Stephen had to fight for the throne against his relative, Koppány, who was supported by large numbers of pagan warriors.
He defeated Koppány mainly with the assistance of foreign knights, including Vecelin, Hont and Pázmány, but also with help from native lords.
He was crowned on 25 December 1000 or 1 January 1001 with a crown sent by Pope Sylvester II.
In a series of wars against semi-independent tribes and chieftainsincluding the Black Hungarians and his uncle, Gyula the Youngerhe unified the Carpathian Basin.
He protected the independence of his kingdom by forcing the invading troops of Conrad II, Holy Roman Emperor, to withdraw from Hungary in 1030.
Stephen established at least one archbishopric, six bishoprics and three Benedictine monasteries; thus the Church in Hungary developed independently of the archbishops of the Holy Roman Empire.
He encouraged the spread of Christianity with severe punishments for ignoring Christian customs.
His system of local administration was based on counties organized around fortresses and administered by royal officials.
Hungary, which enjoyed a lasting period of peace during his reign, became a preferred route for pilgrims and merchants traveling between Western Europe and the Holy Land or Constantinople.
He survived all of his children.
He died on 15 August 1038 and was buried in his new basilica, built in Székesfehérvár and dedicated to the Holy Virgin.
His death caused civil wars which lasted for decades.
He was canonized by Pope Gregory VII, together with his son, Emeric, and Bishop Gerard of Csanád, in 1083.
Stephen is a popular saint in Hungary and the neighboring territories.
In Hungary, his feast day (celebrated on 20 August) is also a public holiday commemorating the foundation of the state, known as State Foundation Day.
