Imperial coronation . Conrad was crowned as Emperor on 26 March 1027, by
Pope John XIX. On 26 March 1027,
Pope John XIX crowned Conrad and his wife Gisela as
emperor and empress, respectively, in
Old Saint Peter's Basilica in
Rome. The event lasted seven days and was attended by Conrad's son and heir
Henry;
Cnut the Great, King of England, Denmark and Norway;
Rudolph III of Burgundy and around 70 senior clerics, including the Archbishops of Cologne, Mainz, Trier, Magdeburg, Salzburg, Milan and Ravenna. Rudolph of Burgundy's attendance suggested surprisingly good relations between Burgundy and the
Holy Roman Empire. During the festivities, a power struggle between the archbishops of Milan and Ravenna ensued and was settled in favour of Milan. Subsequently, Conrad left Rome and toured south to receive
homage from the Southern Italian principalities of
Capua and
Salerno and the
Duchy of Benevento. After his coronation, Conrad issued decrees reorganising the monasteries and dioceses of Italy, with the explicit objective of bringing the
Patriarchate of Venice under imperial control (see the
Schism of the Three Chapters). On 6 April 1027, at a
synod held in the
Lateran Basilica with
Pope John XIX, the emperor addressed the matter by declaring the
Patriarchate of Aquileia superior to the
Patriarchate of Grado, an ally of the
Byzantine Empire. The Aquileian
Poppo had been a loyal supporter of Emperor Henry II, who had appointed him patriarch in 1020. Conrad's action placed the patriarchate at Grado under Poppo's authority, securing Poppo's loyalty by making him the Emperor's top official in northern Italy. The synod also limited the political autonomy of Venice. In so doing, Conrad broke with the policies of his predecessors and revoked Venice's privileged trading status. In May 1027 Conrad returned to Germany in order to attend the funeral of Duke
Henry V of Bavaria at
Regensburg. Conrad asserted his right to appoint the new
Duke of Bavaria. He made the unprecedented decision of choosing his 10-year-old son
Henry, ignoring several suitable candidates who held valid claims to the fief. The young prince assumed Bavarian rule on 24 June 1027. Following Henry's appointment, Conrad held court at Regensburg and decreed that all imperial property in the duchy must be documented. This required the various counts and bishops to report all imperial property in their domains, castles and abbeys. Even the
dowager empress Cunigunde of Luxembourg was required to report to Conrad, who even claimed that Cunegonde's
wittum (money and property she had inherited from her deceased husband Emperor Henry II) belonged to him. These dubious claims to property and the excessive promotion of imperial authority over ducal and clerical affairs throughout Bavaria caused, unsurprisingly, new tension between him and the German aristocracy. In return, the various bishoprics and abbeys of the Empire were granted extensive landholdings and secular authority, providing immunity from the jurisdiction of the secular nobles. As such, the Church officials reported exclusively to the Emperor, acting as his personal vassals. As the Emperor's vassals, the Church officials were subject to the provision of two services: the
servitium regis (royal service) and
servitium militum (military service). Under royal service, the bishops and abbots were required to provide hospitality and accommodations to the Emperor and his court when he arrived. It also required the Church officials to act as quasi-bureaucracy for the Empire. Under military service, the Church was required to supply soldiers for the Emperor's army or to act as diplomats at his direction. Conrad energetically continued this tradition. In his biography of Conrad, the chronicler
Wipo of Burgundy stated the promotion of the Church was of little value to the Emperor. Conrad and the other members of the
Salian dynasty had little interest in the founding of new monasteries. Through their hundred-year dynasty, the Salians only founded one:
Limburg Abbey which was converted from a fortress to a monastery in 1025. The Ottonians established at least eight in their hundred-year reign. Additionally, the Ottonians were active in the establishment of Church affairs, but Conrad was uninterested, only calling five
synods during his reign and usually only to restore peace. Conrad's decisions on Church policy were often left to his wife
Gisela of Swabia. When Archbishop
Aribo of Mainz,
Primate of Germany, died in 1031, Conrad considered both Abbot
Bardo of
Hersfeld Abbey and the renowned
theologian Wazo of Liège, then serving as the dean of the
cathedral chapter for the
Bishop of Liege. Though Conrad favoured Wazo to lead the German Church as Archbishop and Primate, Gisela convinced him to appoint Bardo instead. Bolesław died within two months of his coronation, most likely due to an illness. His son,
Mieszko II Lambert, succeeded him as King, crowned on Christmas, 1025. Upon assuming the Polish throne, Mieszko expelled his older half-brother
Bezprym and his younger brother
Otto Bolesławowic. Otto went west to seek Conrad II's protection. Conrad considered the assumption of the title "king" by Mieszko an act of war and a disregard of his imperial authority, but had to address domestic issues before dealing with Mieszko. In 1026 Conrad II marched into Italy to consolidate imperial authority south of the Alps and to claim the imperial crown from the Pope. In his absence, Duke
Ernest II of Swabia,
Conrad the Younger and Duke
Frederick II of Upper Lorraine rebelled against his authority. The rebels sought the support of Mieszko, which the Polish king granted, promising to take military action against Conrad. Conrad returned to Germany in mid-1027, putting an end to the rebellion before Mieszko could deploy his forces. In preparation for his own invasion of Poland, Conrad developed a closer relationship with King
Cnut of England and Denmark (whose kingdom lay beyond the Empire's northern border). Cnut accompanied Conrad at his imperial coronation in 1027, and Conrad granted Cnut authority over the
March of Schleswig, the land bridge between Denmark and Germany. Fearing the possibility of a joint German-Danish attack, in 1028 Mieszko took the initiative and invaded
Lusatia in the eastern Empire and occupied the territories of the
Lutician Federation, where
West Slavic Polabian tribes had settled and represented the majority of the population since the 10th century after centuries of steady immigration. Slavs had long been the targets of imperial military campaigns, particularly for the punishment and subjugation of
pagan tribes.
Emperor Otto I's lieutenants,
Herman Billung and
Gero, harassed Slavic settlers beginning in the 940s. As part of the
Slavic revolt of 983, the Lutici rebelled against the Empire. In the ensuing war (983–995), the Lutici succeeded in reclaiming their independence and gained control of the
Billung March and
Northern March from the Empire. Though
Emperor Otto III allied with Duke
Bolesław I of Poland to reintegrate them into the Empire, Otto III's death ended the friendly relationship between Poland and the Empire. Instead, Bolesław competed with Otto III's successor, Emperor Henry II, for dominion over the Lutici, causing Henry II to ally the Empire with the Lutici against Poland. Under the
Peace of Bautzen in 1018, all three parties remained in uneasy peace, with Poland allowed to retain the
Margraviate of Meissen. Of the eastern marches, the Empire only kept the
March of Lusatia. Mieszko's 1028 invasion ended the peace. The Lutici sent ambassadors to seek Conrad's protection against Mieszko, which Conrad granted and renewed the German-Lutician alliance. Conrad, seeking to relieve pressure on the Lutici, counter-invaded Poland in 1029 and besieged
Bautzen in the
Margraviate of Meissen. However, faced with a potential invasion by Hungary and the failure of the Lutici to provide their promised contingent of troops, Conrad retreated. In 1030, Poland secured an alliance with Hungary, with Stephen I invading Bavaria while Mieszko invaded Saxony. Conrad responded by allying with
Yaroslav the Wise,
Grand Prince of Kiev, who captured
Red Ruthenia, on Poland's eastern border. In 1031, Conrad concluded a peace treaty with Hungary by ceding the lands between the rivers
Lajta and
Fischa to Hungarian control. Freed from the threat of Hungarian attack, the Emperor was able to focus his attention on Poland. Marching on Mieszko in autumn 1031, Conrad again besieged
Bautzen. Mieszko was crushed by the Holy Roman and Kievan invaders and his exiled brother
Bezprym's rebellion. He surrendered to Conrad in the fall of 1031. The
Treaty of Merseburg provided that Mieszko return the
Margraviate of Meissen and the
March of Lusatia to the Empire.
Treaty of Merseburg Soon after Mieszko had concluded peace with the Empire, he was deposed by
Bezprym, who had been in exile in the
Kievan Rus' since 1025. Bezprym, with Conrad's approval, had persuaded the Kievan Grand Prince
Yaroslav I the Wise to invade Poland and install Bezprym as sovereign. Mieszko fled to
Bohemia where he was imprisoned and
castrated by Duke
Oldřich in retribution for Mieszko's father
Bolesław's blinding of Duke
Boleslaus III, Oldřich's brother, thirty years earlier. Shortly after taking power, Bezprym sent the
Polish regalia to Conrad, officially renouncing the title "king" in favour of the traditional title "duke" and accepting the overlordship of the Empire over Poland. The royal regalia were delivered by Mieszko II's wife,
Richeza of Lotharingia. Bezprym's reign, however, was short. His extreme cruelty caused his half-brother
Otto Bolesławowic to conspire against him. Bezprym's own men murdered him in the spring of 1032, which created a
power vacuum in Poland. Conrad responded by holding a
diet at
Merseburg in 1033 to address the situation. Conrad's wife, Empress
Gisela of Swabia, interceded on Mieszko's behalf and requested he be freed from imprisonment in Bohemia and allowed to regain the Polish throne. Under the terms of the
Treaty of Merseburg, Conrad divided Poland among Mieszko, Otto and Detric, another half-brother. Mieszko was allowed to retain the title of Duke and nominal authority over all of Poland. Now that the Empire had a strong central leader, the treaty significantly increased the Empire's influence over Poland. The regulation was short-lived as in 1033 Otto was killed by one of his own men, and Mieszko II took over his domains. Shortly after, Mieszko expelled Detric and reunited the whole country. Though Mieszko regained his territory, he still was opposed by the nobility and his own subjects. Mieszko did not adopt Bezprym's renunciation of the Polish crown and continued to style himself as King. Mieszko II died soon after in 1034, and upon his death, a
Pagan reaction in Poland erupted. Subsequently, his wife
Richeza and son
Casimir I fled to the Empire. Poland did not stabilize in the wake of Mieszko's exile, forcing Conrad to convene an assembly in July 1033 to issue the
Treaty of Merseburg which restored Mieszko to the Polish throne. Conrad summoned Oldřich to appear at the assembly, but Oldřich refused. His absence raised the ire of the Emperor; Conrad, busy with securing his succession to the Burgundian throne, charged his son Duke
Henry of Bavaria with punishing the recalcitrant Bohemian. At age 17, Henry's march on Bohemia was his first independent military command. The expedition was a complete success, as Henry deposed Oldřich and restored his brother Jaromír to the Bohemian throne. Oldřich's son
Bretislaus I was appointed as Count of
Moravia. Oldřich himself was imprisoned in Bavaria, but in 1034 was pardoned and allowed to return to Bohemia. Oldřich deposed and blinded Jaromír, reclaimed the Bohemian throne, and exiled his son Bretislaus. While the reason for the conflict between father and son has been lost, it is assumed Bretislaus had supported Jaromír over his father. However, Oldřich died suddenly on 9 November 1034, allowing Bretislaus to return from exile. Though Jaromír was offered the throne, he declined in favour of his nephew. Bretislaus was then confirmed as the new Duke of Bohemia by Conrad II.
Hungary With emperor Otto III's approval, Stephen was crowned as the first Christian
king of Hungary on
Christmas Day, 1000. Otto III's successor,
Emperor Henry II, was Stephen's brother-in-law by Stephen's marriage to Henry's sister
Gisela, furthering the friendly relationship between the Empire and Hungary. Under Conrad II, however, relations quickly turned hostile as Conrad pursued a more aggressive policy regarding eastern Europe. Conrad II expelled the
Venetian doge Otto Orseolo, the husband of Stephen's sister
Grimelda of Hungary from Venice in 1026. Conrad also persuaded the Bavarians to accept his own infant son,
Henry, as their duke in 1027, although Stephen's son,
Emeric of Hungary, had a legitimate claim to the
Duchy of Bavaria through his mother. Emperor Conrad planned a marriage alliance with the
Byzantine Empire and dispatched one of his advisors, Bishop
Werner of Strasbourg, to
Constantinople. The bishop presented himself as a pilgrim, but Stephen, who had been informed of his actual purpose, refused to let him enter the country in the autumn of 1027. Conrad's biographer
Wipo of Burgundy recorded that the Bavarians incited skirmishes along the common Imperial-Hungarian border in 1029, causing a rapid deterioration in relations between the two countries. In 1030, open conflict erupted. Conrad launched
an invasion into Hungary but was forced to retreat when the Hungarians successfully used
scorched earth tactics. Conrad departed to address the problem with his stepson
Ernest II, the deposed
Duke of Swabia, leaving matters in Hungary to his son Henry. Henry settled the conflict by 1031 by bestowing titles to eastern Bavarian lands between the
Lajta and
Fischa rivers to the Hungarian nobility. Hungary and the Empire remained at peace from 1031 to Henry's own reign as Emperor in 1040.
Conquest of Burgundy In 1016 King
Rudolph III of Burgundy, ruler of the
Kingdom of Burgundy, was left without a male heir, and so
Henry II seized the opportunity and forced Rudolph to name him as successor. Henry II, the son of Rudolph's sister
Gisela of Burgundy, was his nephew and closest living male relative. However, Henry predeceased Rudolph in 1024. Soon, Henry's successor Conrad II claimed to have acquired Henry's rights to the Burgundian succession, which Rudolph disputed. Count
Odo II of Blois, who had strong family ties with Rudolph, also claimed the succession. Conrad II met Rudolph III in August 1027 near
Basel to settle the dispute. Henry II's widowed wife, Empress
Cunigunde of Luxembourg, mediated between the two parties. An agreement was reached that allowed Conrad II to succeed to the Burgundian throne upon Rudolph's death under the same conditions as Henry II. In return, Rudolph was allowed to retain independent rule over his kingdom. Rudolph died on 6 September 1032, while Conrad was on campaign against Duke
Mieszko II of Poland. Upon Mieszko's surrender, Conrad marched his army to Burgundy during the winter of 1032/1033. Conrad's rival to the Burgundian throne, Count Odo II of Blois had already invaded the kingdom to secure his rule and controlled large sections of the kingdom's western territories. On 2 February 1033, Conrad arrived at
Vaud, where he held an assembly at the
Abbey of Payerne and was crowned King of Burgundy. Initially, Conrad made little progress against Odo and had to withdraw to
Zürich in March. In April 1033 he negotiated a treaty of alliance with
Henry I of France, which was completed at the end of May in a personal interview at
Deville on the Meuse. Both monarchs had Odo for an enemy, since he had supported the claims of Henry I's younger brother to the French crown. Conrad might therefore have been given a free hand by his ally to invade Odo's French fiefs. In two large-scale military summer campaigns in 1033 and 1034, Conrad defeated Odo. On 1 August 1034, Conrad officially incorporated Burgundy into the
Holy Roman Empire at a ceremony held in the
Cathedral of Geneva. Though Burgundy had been brought under full imperial control, the kingdom was allowed a remarkable degree of autonomy. Conrad rarely intervened in its affairs following his coronation, returning only in 1038 to announce his son
Henry as the kingdom's future ruler. Crucially, the conquest of Burgundy augmented the influence and dignity of the Emperor to the benefit of the Empire. With Burgundy secured, Conrad controlled the western Alpine passes into Italy and could easily block foreign invasions. ==Politics==
