Stephen I, also known as King Saint Stephen (Hungarian: Szent István király [ˌsɛnt ˈiʃtvaːn kiraːj]; Latin: Sanctus Stephanus; Slovak: Štefan I. or Štefan Veľký; c. 975 – 15 August 1038), was the last grand prince of the Hungarians between 997 and 1000 or 1001, and the first king of Hungary from 1000 or 1001 until his death in 1038. The year of his birth is uncertain, but many details of his life suggest that he was born in, or after, 975, in Esztergom. He was given the pagan name Vajk at birth, but the date of his baptism is unknown. He was the only son of Grand Prince Géza and his wife, Sarolt, who was descended from a prominent family of gyulas. Although both of his parents were baptized, Stephen was the first member of his family to become a devout Christian. 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 with the assistance of foreign knights including Vecelin, Hont and Pázmány, and 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 chieftains—including the Black Hungarians and his uncle, Gyula the Younger—he 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, leading the Church in Hungary to develop independently from the archbishops of the Holy Roman Empire. He encouraged the spread of Christianity by meting out severe punishments for ignoring Christian customs. His system of local administration was based on counties organized around fortresses and administered by royal officials. Hungary enjoyed a lasting period of peace during his reign and became a preferred route for pilgrims and merchants traveling between Western Europe, the Holy Land and Constantinople.
Stephen survived all of his children, dying on 15 August 1038, aged 62 or 63. He was buried in his new basilica, built in Székesfehérvár and dedicated to the Holy Virgin. His death was followed by 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 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.
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 historians—including Pál Engel and Gyula Kristó—propose 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 Kristó proposes that he only received baptism just before his father's death in 997.
Stephen's official hagiography, written by Bishop Hartvic and sanctioned by Pope Innocent III, narrates that he "was fully instructed in the knowledge of the grammatical art" in his childhood. This implies that he studied Latin, though some scepticism is warranted as few kings of this era were able to write. His two other late 11th-century hagiographies do not mention any grammatical studies, stating only that he "was brought up by receiving an education appropriate for a little prince". Kristó says that the latter remark only refers to Stephen's physical training, including his participation in hunts and military actions. According to the Illuminated Chronicle, one of his tutors was a Count Deodatus from Italy, who later founded a monastery in Tata.
According to Stephen's legends, Grand Prince Géza convoked an assembly of the Hungarian chieftains and warriors when Stephen "ascended to the first stage of adolescence", at the age of 14 or 15. Géza nominated Stephen as his successor and all those present took an oath of loyalty to the young prince. Györffy writes, without identifying his source, that Géza appointed his son to rule the "Nyitra ducate" around that time. Slovak historians, including Ján Steinhübel and Ján Lukačka, accept Györffy's view and propose that Stephen administered Nyitra (now Nitra, Slovakia) from around 995.
Géza arranged Stephen's marriage to Gisela, daughter of Henry II, Duke of Bavaria, in or after 995. This marriage established the first family link between a Hungarian ruler and a Western European ruling house, as Gisela was closely related to the Ottonian dynasty of Holy Roman Emperors. According to popular tradition preserved in the Scheyern Abbey in Bavaria, the ceremony took place at the Scheyern castle and was celebrated by Saint Adalbert. Gisela was accompanied to her new home by Bavarian knights, many of whom received land grants from her husband and settled in Hungary, helping to strengthen Stephen's military position. According to Györffy, Stephen and his wife "presumably" settled in Nyitra after their marriage.
Grand Prince Géza died in 997. Stephen convoked an assembly at Esztergom where his supporters declared him grand prince. Initially, he only controlled the northwestern regions of the Carpathian Basin; the rest of the territory was still dominated by tribal chieftains. Stephen's ascension to the throne was in line with the principle of primogeniture, which prescribed that a father was succeeded by his son. On the other hand, it contradicted the traditional idea of seniority, according to which Géza should have been succeeded by the most senior member of the Árpád dynasty, which was Koppány at that time. Koppány, who held the title Duke of Somogy, had for many years administered the regions of Transdanubia south of Lake Balaton.
Koppány proposed to Géza's widow, Sarolt, in accordance with the pagan custom of levirate marriage. He also announced his claim to the throne. Although it is not impossible that Koppány had already been baptized, in 972, most of his supporters were pagans, opponents of the Christianity represented by Stephen and his predominantly German retinue. A charter of 1002 for the Pannonhalma Archabbey writes of a war between "the Germans and the Hungarians" when referring to the armed conflicts between Stephen and Koppány. Even so, Györffy says that Oszlar ("Alan"), Besenyő ("Pecheneg"), Kér and other place names, referring to ethnic groups or Hungarian tribes in Transdanubia around the supposed borders of Koppány's duchy, suggest that significant auxiliary units and groups of Hungarian warriors—who had been settled there by Grand Prince Géza—fought in Stephen's army.
