The crowning legitimizes Hungary as a Western kingdom independent of the Holy Roman and East Roman empires.
It also gives Stephen virtually absolute power, which he uses to strengthen the Roman Catholic Church and Hungary.
Stephen orders the people to pay tithes and requires every tenth village to construct a church and support a priest.
Stephen donates land to support bishoprics and monasteries, requires all persons except the clergy to marry, and bars marriages between Christians and pagans.

The Struggle for Reims: Arnulf, Charles of Lorraine, and the Carolingian Resistance (989–991)
The death of Archbishop Adalberon of Reims on January 23, 989, created an important vacancy in one of the most politically influential sees in West Francia. His chosen successor, Gerbert of Aurillac, was a natural candidate, given his loyalty to Hugh Capet and his opposition to the Carolingian cause. However, the election that followed took an unexpected turn, leading to a brief Carolingian resurgence under Charles of Lorraine.
Hugh Capet’s Strategic Mistake: The Appointment of Arnulf
Rather than securing the election of Gerbert, Hugh Capet, in March 989, instead accepted the appointment of Arnulf, the illegitimate son of Lothair of France and nephew of Charles of Lorraine, the last legitimate Carolingian heir.
- The choice was likely a compromise intended to pacify lingering Carolingian sympathizers while maintaining royal authority over Reims.
- However, Arnulf soon proved disloyal, betraying Hugh in favor of his Carolingian uncle.
The Carolingian Coup: Charles of Lorraine Takes Reims and Laon (September 989)
By September 989, Arnulf facilitated an attempt to place Charles of Lorraine on the throne.
- Charles launched a military campaign, seizing both Reims and Laon, two of the most important cities of the realm.
- With control over Reims, where West Frankish kings were traditionally crowned, Charles briefly posed a serious challenge to Capetian rule.
A Short-Lived Threat
Although Charles of Lorraine succeeded in capturing key cities, his attempt to claim the French throne ultimately failed.
- Hugh Capet and his son Robert II responded decisively, moving to counter the Carolingian resurgence.
- By 991, Charles and Arnulf would be captured through treachery, marking the final collapse of Carolingian legitimacy in West Francia.
Legacy: The Securing of Capetian Rule
The events of 989–991 demonstrated the fragility of Capetian authority in its early years. Hugh Capet’s decision to allow a Carolingian prince to assume power in Reims had nearly led to a restoration of the Carolingian line. However, the failure of Charles of Lorraine to garner widespread support and his subsequent fall in 991 ensured that the Capetian dynasty remained unchallenged, solidifying their hold on the French throne.
The Council of Mousson and the Struggle for the Archbishopric of Reims (995–996)
Following the contested deposition of Archbishop Arnulf of Reims by Hugh Capet’s synod in 991, Pope John XVsought to settle the matter through a broader council that would include both French and German bishops. However, Capetian resistance to papal interference led to a stalemate, highlighting the growing conflict between royal authority and papal supremacy.
The Council of Mousson: French Obstruction and German Support
- The Papal Legate, sent by John XV, was tasked with convening a council of bishops from both France and the Holy Roman Empire at Mousson, a neutral site near the imperial border.
- However, only the German bishops managed to attend; the French bishops were blocked by Hugh Capet and Robert II, who prevented their participation, fearing a ruling against the Capetian-backed Archbishop Gerbert of Aurillac.
- Despite this obstruction, the German bishops, under imperial influence, ruled that Arnulf’s deposition was illegal, effectively nullifying the decisions made at the Synod of Reims (991).
Gerbert’s Suspension and His Defense
- As a result of the ruling, Gerbert of Aurillac, who had been installed as Archbishop of Reims by Hugh Capet, was suspended from his episcopal office.
- Gerbert, a brilliant scholar and political strategist, argued that the decree against him was unlawful, appealing to imperial and theological authorities in his defense.
- Despite his efforts, he lost official recognition as Archbishop of Reims, forcing him to seek support from Emperor Otto III, who would later play a decisive role in his career.
Aftermath: Papal and Imperial Maneuvering
- The failure of the French bishops to attend Mousson demonstrated the Capetians' growing defiance of papal authority, foreshadowing future conflicts between the French monarchy and the papacy.
- Gerbert’s alignment with the Holy Roman Empire led to his eventual rise as Pope Sylvester II (999–1003), where he would continue to champion imperial-papal cooperation against Capetian interests.
- Meanwhile, Arnulf was restored in name, but his authority in Reims remained weak and contested, reflecting the Capetians’ firm grip on ecclesiastical appointments in their realm.
Significance
The Council of Mousson marked a turning point in the struggle for control over the French Church, revealing both the Capetians' determination to dominate episcopal appointments and the papacy’s limited ability to enforce its rulings within France. While the Holy Roman Empire upheld papal legitimacy, the Capetians successfully cemented their control over the French episcopate, setting a precedent for the future Gallican Church and the French monarchy’s increasing independence from Rome.
Leopold I, Margrave of Austria, travels to Würzburg in 994 to mediate a dispute between his cousin Henry of Schweinfurt and Bishop Bernward von Rothenburg of Würzburg, one of whose knights Henry had seized and blinded.
At a tournament held on July 8, Leopold is hit in the eye by an arrow directed at his cousin.
Two days later, on July 10, Leopold dies from his injuries.
He is buried in Würzburg.
The authority of Adelaide of Italy, grandmother of Otto III, has gradually waned until Otto reaches the age of fourteen in 994.
At an assembly of the Imperial Diet held in Solingen in September 994, Otto is granted the ability to fully govern the kingdom without the need of a regent.
Adelaide is now free to devote herself exclusively to works of charity, notably the foundation or restoration of religious houses.
The young king’s mental gifts are considerable, and have been carefully cultivated by Bernward, afterwards bishop of Hildesheim, and by Gerbert of Aurillac, archbishop of Reims, so that he is called "the wonder of the world."
A further synod declares Arnulf's deposition invalid in 995.
Gerbert now becomes the teacher of Otto III.
Otto is attempting to revive the glory and power of ancient Rome with himself at the head of a theocratic state.
In 996, he had come to the aid of Pope John XV at the pope's request to put down the rebellion of the Roman nobleman Crescentius II.
Stopping to be acclaimed King of Lombardy at Pavia, the imperial capital, …
…Otto fails to reach Rome before the Pope dies.
Once in Rome, he engineers the election of his twenty-four-year-old chaplain and cousin Bruno of Carinthia as Pope Gregory V, the first German pope, on May 3.
The new pontiff, son of the Salian Otto I, Duke of Carinthia, who was a grandson of the Emperor Otto I the Great, had crowned Otto emperor on May 21, 996, in Rome.
Here, his main advisors are two of the main characters of this age, his tutor Gerbert of Aurillac and the bishop Adalbert of Prague.
Together with these two visionary men, influenced by the Roman ruins and perhaps by his Greek mother, Otto devises a dream of restoration of a universal Empire formed by the union of the Papacy, Constantinople and Rome.
He also introduces some court customs in Greek.
Highly educated and emotionally receptive to exotic influences, Otto devotes more attention to imperial and Italian affairs than to German.
A few days after Otto III's coronation, the emperor and the pope hold a synod in which Arnulf is ordered to be restored to the See of Reims, and Gerbert is condemned as an intruder.
Politically, Gregory V acts consistently as the Emperor's representative in Rome and grants many exceptional privileges to monasteries within the Holy Roman Empire.
Johannes Philagathos, called by Latin chroniclers Piligato or Filagatto, had been the chaplain of Theophanu, the Empress consort of Emperor Otto II, who had come from Constantinople.
Twice he had acted as Imperial chancellor in Italy for Otto II, in 980-982, whereupon he was appointed Abbot of Nonantola, and in 991-992.
Between his sojourns in Italy he had been appointed tutor to the Emperor's then seven-year-old son, Otto III, in 987.
By the Empress's persuasion he had been appointed bishop of Piacenza, and had been sent to Constantinople to accompany home an imperial princess for the younger Otto.
After Otto leaves Rome in 997, the city magnate Crescentius II violently unseats Pope Gregory and, with the active support of the Eastern Emperor, Basil II, acclaims Philagathos as Pope John XVI, chosen in revolt against the will of the youthful Emperor.
