is a popular saint in Hungary and 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. Early years ( 975–997) Stephen's birth date is uncertain as it was not recorded in contemporaneous documents. Hungarian and Polish chronicles written centuries later give three different years: 967, 969 and 975. The unanimous testimony of his three late 11th-century or early 12th-century hagiographies and other Hungarian sources, which state that Stephen was "still an adolescent" in 997, substantiate the reliability of the latest year (975). Stephen's Lesser Legend adds that he was born in Esztergom, which implies that he was born after 972 because his father, Géza, Grand Prince of the Hungarians, chose Esztergom as royal residence around that year. Géza promoted the spread of Christianity among his subjects by force, but never ceased worshipping pagan gods. Both his son's Greater Legend and the nearly contemporaneous Thietmar of Merseburg described Géza as a cruel monarch, suggesting that he was a despot who mercilessly consolidated his authority over the rebellious Hungarian lords. Hungarian chronicles agree that Stephen's mother was Sarolt, daughter of Gyula, a Hungarian chieftain with jurisdiction either in Transylvania or in the wider region of the confluence of the rivers Tisza and Maros. Many historiansincluding Pál Engel and Gyula Kristópropose that her father was identical with "Gylas", who had been baptized in Constantinople around 952 and "remained faithful to Christianity", according to Byzantine chronicler John Skylitzes. However, this identification is not unanimously accepted; historian György Györffy states that it was not Sarolt's father, but his younger brother, who was baptized in the Byzantine capital. In contrast with all Hungarian sources, the Polish-Hungarian Chronicle and later Polish sources state that Stephen's mother was Adelhaid, an otherwise unknown sister of Duke Mieszko I of Poland, but the reliability of this report is not accepted by modern historians. Stephen was born as Vajk, a name derived from the Turkic word baj, meaning "hero", "master", "prince" or "rich". Stephen's Greater Legend narrates that he was baptized by the saintly Bishop Adalbert of Prague, who stayed in Géza's court several times between 983 and 994. However, Saint Adalbert's nearly contemporaneous Legend, written by Bruno of Querfurt, does not mention this event. Accordingly, the date of Stephen's baptism is unknown: Györffy argues that he was baptized soon after birth, while
