Henry II (German: Heinrich II; Italian: Enrico II; Latin: Henricus; 6 May 973 – 13 July 1024), also known as Saint Henry, Obl. S. B., was Holy Roman Emperor (Latin: Romanorum Imperator) from 1014. He died without an heir in 1024 and was the last ruler of the Ottonian line. As Duke of Bavaria, appointed in 995, Henry became King of the Romans (Latin: Rex Romanorum) following the sudden death of his second cousin, Emperor Otto III in 1002, was made King of Italy (Latin: Rex Italiae) in 1004, and crowned emperor by Pope Benedict VIII in 1014.
The son of Henry II, Duke of Bavaria, and his wife Gisela of Burgundy, Henry was a great-grandson of German king Henry the Fowler and a member of the Bavarian branch of the Ottonian dynasty. Since his father had rebelled against two previous emperors, the younger Henry spent long periods of time in exile, where he turned to Christianity at an early age, first finding refuge with Bishop Abraham of Freising and later during his education at the cathedral school in Hildesheim. He succeeded his father as Duke of Bavaria in 995 as Henry IV (Henry III having briefly interrupted his father's rule). As duke, he attempted to join his second-cousin, Emperor Otto III, in suppressing a revolt against imperial rule in Italy in 1002. Before Henry could arrive, however, Otto III died of fever, leaving no heir. After defeating several contenders to the throne, he was crowned Henry II, King of Germany, on 9 July 1002 as the first in a line of kings to adopt the title Rex Romanorum as an antedate to his coronation in Rome as Imperator Romanorum. On 15 May 1004, he was anointed King of Italy (Rex Italiae). In that same year, Henry II joined Duke Jaromír of Bohemia in his struggle against the Poles, thus effectively incorporating the Duchy of Bohemia into the Holy Roman Empire.
Unlike his predecessor Otto III, who had imposed plans on sovereign administration and active political involvement in Italy, Henry spent most of his reign concerned with the renovation ("renewal") of the imperial territories north of the Alps, a policy summed up on his seal as Renovatio regni Francorum, which replaced Otto's Renovatio imperii Romanorum. A series of conflicts with the Polish Duke Bolesław I, who had already conquered a number of countries surrounding him, required Henry II's full attention and years of political and military maneuvering. Henry did, however, lead three expeditions into Italy to enforce his feudal claim (Honor Imperii): twice to suppress secessionist revolts and once to address Byzantine attempts to obtain dominance over southern Italy. On 14 February 1014, Pope Benedict VIII crowned Henry Holy Roman Emperor in Rome.
The rule of Henry II has been characterized as a period of centralized authority throughout the Holy Roman Empire. He consolidated his power by cultivating personal and political ties with the Catholic Church. He greatly expanded the Ottonian dynasty's custom of employing clerics as counterweights against secular nobles. Through donations to the Church and the establishment of new dioceses, Henry strengthened imperial rule across the Empire and increased control over ecclesiastical affairs. He stressed service to the Church and promoted monastic reform. For his remarkable personal piety and enthusiastic promotion of the Church, he was canonized by Pope Eugene III in 1146. He is the only medieval German monarch ever to have been honoured as a saint. Henry II's wife was the equally pious Empress Cunigunde, who was canonized in 1200 by Pope Innocent III. As the union produced no children, the German nobles elected Conrad II, a great-great-grandson of Emperor Otto I, to succeed him after he died in 1024. Conrad was the first of the Salian dynasty of emperors.
Henry was born in May 973, the son of Duke Henry II of Bavaria, and Gisela of Burgundy. Through his father, he was the grandson of Duke Henry I of Bavaria, and the great-grandson of King Henry I of Germany. By his mother, he was the grandson of King Conrad I of Burgundy, and the great-grandson of King Rudolf II of Burgundy.
The elder Henry came into conflict with his cousin Otto II, Holy Roman Emperor, in 974. The elder Henry and Otto II disputed each other's claims to authority over the Duchy of Swabia: Henry claimed the duchy as his birthright. At the same time, Otto II maintained his right to name a duke of his choosing. After an initial failed revolt, Otto II imprisoned the elder Henry in Ingelheim. After escaping, Henry again revolted against Otto II. When this second revolt failed, Otto II deposed Henry as Duke of Bavaria. He sent him into exile under the custody of the Bishop of Utrecht in April 978. As a consequence of his revolt, the Emperor stripped the Duchy of Bavaria of its southeastern territories bordering Italy and formed the Duchy of Carinthia.
During his father's exile, the younger Henry lived in Hildesheim. As a child, he was educated in the Christian faith by Bishop Wolfgang of Regensburg, and then studied at the Hildesheim Cathedral. The Emperor himself ensured that the younger Henry received an ecclesiastical education so that, by becoming a religious official, he would be prevented from participating in the Imperial government.
The death of Otto II in 983 allowed the elder Henry to be released from custody and to return from exile. The elder Henry claimed regency over Otto III, the three-year-old child of Otto II. After a failed attempt to claim the German throne for himself in 985, the elder Henry relinquished the regency to the child's mother Theophanu. In return for his submission to the child king, Henry was restored as Duke of Bavaria. The younger Henry, now thirteen years old, was appointed regent of Bavaria. When the elder Henry died in 995, the younger Henry was elected by the Bavarian nobles as the new duke to succeed his father.
In 999, Henry married Cunigunde of Luxembourg, a daughter of Count Siegfried of Luxembourg. This marriage granted him an extensive network of contacts in Germany's western territories.
In 1001, Emperor Otto III experienced a revolt against his reign in Italy. The Emperor sent word for Henry II to join him with reinforcements from Germany, but then died unexpectedly in January 1002. Otto was only 21 at the time of his death and had left no children and no instructions for the Imperial succession. In the Ottonian dynasty, succession to the throne had belonged to the Saxon branch, not the Bavarian line of which Henry was a member. Rival candidates for the throne, including Count Ezzo of Lotharingia, Margrave Eckard I of Meissen, and Duke Herman II of Swabia, strongly contested Henry's right to succeed Otto III.
As the funeral procession moved through the Duchy of Bavaria in February 1002, Henry met the procession in Polling, just north of the Alps. To legitimise his claims, Henry demanded that Archbishop Heribert of Cologne give him the Imperial Regalia, chief among them being the Holy Lance. Heribert, however, had sent these ahead of the procession, possibly out of distrust of Henry and possibly because he favoured the succession of his relative, Duke Herman II of Swabia, as the next king. To force Herman II to relinquish the Holy Lance to him, Henry imprisoned the Archbishop and his brother, the Bishop of Würzburg. With neither the symbols of imperial authority, the crown jewels, nor the cooperation of Heribert, Henry was unable to convince the nobles attending Otto III's funeral procession to elect him as king. A few weeks later, at Otto III's funeral in Aachen Cathedral, Henry again attempted to gain the support of the kingdom's nobles and was again rejected.
So it was without the support of the kingdom's nobility that Henry took the radical action of having himself anointed and crowned King of Germany ("Rex Romanorum") by Willigis, Archbishop of Mainz on 9 July 1002 at Mainz, in present-day Germany. Henry's action marked the first time a German king was not crowned in Aachen Cathedral since Emperor Otto I began the tradition in 936, and the first time a German king assumed the throne without being elected by the German nobility. Under the regal name of "King Henry II", he appeared before the Saxons in mid-July in full regal apparel. There, Henry convinced Bernard I, Duke of Saxony, to support his claims to the throne. In return for his support, Henry guaranteed Bernard's right to rule the Saxons and to represent their interests before him.
