Pope Sylvester II in the context of "Armillary sphere"

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 Ottonian Renaissance was a renaissance of Byzantine and Late Antique art in Central and Southern Europe that accompanied the reigns of the first three Holy Roman Emperors of the Ottonian (or Saxon) dynasty: Otto I (936–973), Otto II (973–983), and Otto III (983–1002), and which in large part depended upon their patronage. The leading figures in this movement were Pope Sylvester II and Abbo of Fleury. Renewed contact between the Ottonian court and Byzantine Constantinople spurred the hybridisation of Eastern-Byzantine and Western-Latin cultures, particularly in arts, architecture and metalwork, while the Ottonians revitalised the cathedral school network which promoted learning based on the seven liberal arts. Ottonian intellectual activity was largely a continuation of Carolingian works, but circulated mainly in the cathedral schools and the courts of bishops (such as Liège, Cologne and Magdeburg), rather than the royal court.

Robert II (c. 972 – 20 July 1031), called the Pious (French: le Pieux) or the Wise (French: le Sage), was King of the Franks from 996 to 1031, the second from the Capetian dynasty. Crowned Junior King in 987, he assisted his father on military matters (notably during the two sieges of Laon, in 988 and 991). His solid education, provided by Gerbert of Aurillac (the future Pope Sylvester II) in Reims, allowed him to deal with religious questions of which he quickly became the guarantor (he headed the Council of Saint-Basle de Verzy in 991 and that of Chelles in 994). Continuing the political work of his father, after becoming sole ruler in 996, he managed to maintain the alliance with the Duchy of Normandy and the County of Anjou and thus was able to contain the ambitions of Count Odo II of Blois.

Robert II distinguished himself with an extraordinarily long reign for the time. His 35-year-long reign was marked by his attempts to expand the royal domain by any means, especially by his struggle to gain the Duchy of Burgundy (which ended in 1005 with his victory) after the death in 1002 without male descendants of his paternal uncle Duke Henry I, after a war against Otto-William of Ivrea, Henry I's stepson and adopted by him as his heir. His policies earned him many enemies, including three of his sons.
