Conrad II, Holy Roman Emperor in the context of "County of Burgundy"

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.

The Salian dynasty or Salic dynasty (German: Salier) was a dynasty in the High Middle Ages. The dynasty provided four kings of Germany (1024–1125), all of whom went on to be crowned Holy Roman emperors (1027–1125).

After the death of the last Ottonian emperor in 1024, the Kingdom of Germany and later the entire Holy Roman Empire passed to Conrad II, a Salian. He was followed by three more Salian rulers: Henry III, Henry IV, and Henry V. They established their monarchy as a major European power. The Salian dynasty developed a permanent administrative system based on a class of public officials answerable to the crown.

Speyer Cathedral, officially the Imperial Cathedral Basilica of the Assumption and St Stephen, in Latin: Domus sanctae Mariae Spirae (German: Dom zu Unserer lieben Frau in Speyer) in Speyer, Germany, is the seat of the Roman Catholic Bishop of Speyer and is suffragan to the Roman Catholic Archdiocese of Bamberg. The cathedral, which is dedicated to St. Mary, patron saint of Speyer ("Patrona Spirensis") and St. Stephen is generally known as the Kaiserdom zu Speyer (Imperial Cathedral of Speyer). Pope Pius XI raised Speyer Cathedral to the rank of a minor basilica of the Roman Catholic Church in 1925.

Begun in 1030 under Conrad II, with the east end and high vault of 1090–1103, the imposing triple-aisled vaulted basilica of red sandstone is the "culmination of a design which was extremely influential in the subsequent development of Romanesque architecture during the 11th and 12th centuries". As the burial site for Salian, Staufer and Habsburg emperors and kings the cathedral is regarded as a symbol of imperial power. With the Abbey of Cluny in ruins, it is the largest remaining Romanesque church and building. It is considered to be "a turning point in European architecture",one of the most important architectural monuments of its time and one of the finest Romanesque monuments.
