Henry was the second son of EmperorFrederick Barbarossa andBeatrice I, Countess of Burgundy. Well educated in theLatin language, as well asRoman andcanon law, Henry was also a patron of poets and a skilled poet himself. In 1186 he married Constance of Sicily. Henry, stuck in the Hohenstaufen conflict with theHouse of Welf until 1194, had to enforce the inheritance claims by his wife against her nephew CountTancred of Lecce. Henry's attempt to conquer theKingdom of Sicily failed at thesiege of Naples in 1191 due to an epidemic, with Empress Constance captured. Based on an enormous ransom for the release and submission ofKing Richard I of England, he conquered Sicily in 1194; however, the intended unification with theHoly Roman Empire ultimately failed due to the opposition of thePapacy. In Sicily, Henry had a reputation for ruthless suppression of political opponents.[1] To this day, he is sometimes given the epithet "the Cruel" (il crudele) by Italian historiographers.[2][3]
Henry threatened to invade theByzantine Empire after 1194 and succeeded in extracting a ransom, theAlamanikon, from EmperorAlexios III Angelos in return for cancelling the invasion. He made theKingdom of Cyprus and theArmenian Kingdom of Cilicia formal subjects of the empire and compelledTunis andTripolitania to pay tribute to him. In 1195 and 1196, he attempted to turn the Holy Roman Empire from an elective to a hereditary monarchy, the so-calledErbreichsplan, but met strong resistance from theprince-electors. Henry pledged to go oncrusade in 1195 and began preparations. A revolt in Sicily was crushed in 1197. The Crusaders set sail for theHoly Land that same year but Henry died of malaria atMessina on 28 September 1197 before he could join them. His death plunged the Empire into the chaos of theGerman throne dispute for the next 17 years.
Henry accompanied his father on hisItalian campaign of 1174–76 against theLombard League, whereby he was educated byGodfrey of Viterbo and associated withminnesingers likeFriedrich von Hausen,Bligger von Steinach andBernger von Horheim. Henry was fluent inLatin and, according to the chroniclerAlberic of Trois-Fontaines, was "distinguished by gifts of knowledge, wreathed in flowers of eloquence, and learned in canon and Roman law". He was a patron of poets and poetry, and he almost certainly composed the songKaiser Heinrich, now among theWeingarten Song Manuscripts. According to his rank and withImperial Eagle (Reichsadler),regalia, and a scroll, he is the first and foremost to be portrayed in the famousCodex Manesse, a 14th-century songbook manuscript featuring 140 reputed poets; at least three poems are attributed to a young and romantically minded Henry VI. In one of those he describes a romance that makes him forget all his earthly power, and neither riches nor royal dignity can outweigh his yearning for that lady (ê ich mich ir verzige, ich verzige mich ê der krône – before I give her up, I'd rather give up the crown).
Having returned toGermany in 1178, Henry supported his father against insurgent dukeHenry the Lion. He and his younger brotherFrederick received the knightlyaccolade at theDiet of PentecostMainz in 1184.[6] That same year, Henry had almost lost his life during theErfurt latrine disaster, where about 60 nobles had perished in a latrine cesspit after theErfurt Cathedral’s second story floor had collapsed. Henry had only survived due to being seated in a separate part of the alcove which was made of stone.[7]
The emperor had already entered into negotiations with KingWilliam II of Sicily tobetroth his son and heir with William's aunt Constance by 1184. Constance, almost 30 years old at that time, was said to have been confined inSantissimo Salvatore, Palermo as a nun since childhood to keepcelibacy due to a prediction that "her marriage would destroy Sicily" despite having become the sole legitimate heir to William as the marriage of the latter had remained childless; and, after the latter's death in November 1189, Henry had the opportunity of adding theSicilian crown to the imperial one. He and Constance were married on 27 January 1186 inMilan.[8]
In the Hohenstaufen conflict withPope Urban III, Henry moved to theMarch of Tuscany, and with the aid of his deputyMarkward von Annweiler devastated the adjacent territory of thePapal States. Back in Germany, he became sovereign ruler of the Empire, as his father had died while on theThird Crusade in 1190. Henry tried to secure his rule in theLow Countries by elevating CountBaldwin V of Hainaut to amargrave ofNamur, and at the same time he tried to reach a settlement with rivalling DukeHenry of Brabant. Further difficulties arose when the exiled Welf dukeHenry the Lion returned fromEngland and began to subdue large estates in his formerDuchy of Saxony. A Hohenstaufen campaign to Saxony had to be abandoned when King Henry received the message of the death of King William II of Sicily on 18 November 1189. The Sicilian vice-chancellorMatthew of Ajello pursued the succession of Count Tancred of Lecce and gained the support of theRoman Curia.
To assert his own rights in the inheritance dispute, Henry initially supported Tancred's rival CountRoger of Andria and made arrangements for a campaign to Italy. The next year he concluded a peace agreement with Henry the Lion atFulda and moved farther southwards toAugsburg, where he learned that his father had died on crusade attempting to cross theSaleph River nearSeleucia in theKingdom of Cilicia (now part ofTurkey) on 10 June 1190.[9]
Frederick Barbarossa with his sons Henry and Frederick,Historia Welforum, Weingarten Abbey,c. 1180A depiction ofPope Celestine III crowning Henry VI with his foot. The story of popes crowning emperors with their feet was a popular medieval legend, often intended to show the superiority of papal authority over secular authority. In the case of Henry and Celestine, the story of Celestine crowning the emperor with his right foot and then kicking the crown off his head came from the English chroniclerRoger of Howden.[10][11]
While he sent an Imperial army to Italy, Henry initially stayed in Germany to settle the succession ofLouis III, Landgrave of Thuringia, who had also died on the Third Crusade. He had planned to seize theThuringian landgraviate as a reverted fief, but Louis' brotherHermann was able to reach his enfeoffment. The next year, the king followed his army across theAlps. InLodi he negotiated withEleanor of Aquitaine, widow of KingHenry II of England, to break the engagement of her son King Richard withAlys, a daughter of late KingLouis VII of France. He hoped to deteriorate English-French relations and to isolate Richard, who had offended him by backing Count Tancred in Sicily. Eleanor acted cleverly; she reached Henry's assurance that he would not interfere in her son's conflict with KingPhilip II of France, and she would also prevent the marriage of Henry's younger brotherConrad withBerengaria of Castile to confine the Hohenstaufen claims to power.
Henry entered into further negotiations with the Lombard League cities and withPope Celestine III on hisImperial coronation, and cededTusculum to the Pope. At Easter Monday on 15 April 1191, inRome, Henry and his consort Constance were crowned Emperor and Empress by Celestine. The crown of Sicily, however, was harder to gain, as the Sicilian nobility had chosen Count Tancred of Lecce as their king. Henry began his work campaigning inApulia and besieging Naples, but he encountered resistance when Tancred's vassalMargaritus of Brindisi came to the city's defence, harassed Henry'sPisan navy, and nearly destroyed the later arrivingGenoese contingent. Moreover, the Imperial army had been heavily hit by an epidemic, and Henry ultimately had to abandon the siege. Upon his retreat, those cities that had surrendered to Henry resubmitted to Tancred. As a result, Constance, who was left in the palace ofSalerno as a sign that Henry would soon return, was betrayed and handed over to Tancred.[9]
Henry had to return to Germany when he learned that Henry the Lion had again incited a conflict with the SaxonHouse of Ascania and theCounts of Schauenburg. His sonHenry of Brunswick deserted from the Imperial army in Italy and was ostracized by the emperor at theHoftag inWorms at Pentecost 1192. However, Henry VI had to realise that his powers were limited: after his closest ally in Saxony, ArchbishopWichmann of Magdeburg died, he concluded another armistice with inflammatory Henry the Lion.
Meanwhile, despite the fact that his wife had been captured by Sicilians, Henry refused Celestine III's offers to make peace with Tancred. While Tancred would not permit Constance to be ransomed unless Henry recognized him, Henry complained of her capture to Celestine. In June 1192 Constance was released on the intervention of Pope Celestine III, who in return recognized Tancred as King of Sicily. Constance was to be sent to Rome for Celestine III to put pressure on Henry, but German soldiers managed to set up an ambush on the border of Papal States and freed Constance.

On the other hand, the emperor was able to strengthen his power base in theDuchy of Swabia, when he inherited the possessions of Henry the Lion's cousinWelf VI. During the election of a newBishop of Lüttich (Liège) in September 1191, he favoredAlbert de Rethel for Albert was a maternal-uncle of Empress Constance, whom both he and Constance had planned to be the next bishop of Liège, but at the time of election Empress Constance had been imprisoned by Sicilians, and the other candidateAlbert of Louvain the brother of Duke Henry of Brabant gained more support. In January 1192 Henry claimed the election was under dispute and appointed his newly made imperial chancellorLothar of Hochstaden, provost of the church of St Cassius in Bonn and brother of Count Dietrich of Hochstaden instead, and in September 1192 he proceeded toLiège to enforce the succession. The majority of the electors of Liège accepted the imperial decision because of the emperor's threat, and Albert de Rethel also relinquished and indignantly refused a financial settlement offered by the emperor. Albert of Louvain had to yield and sought support from the pope in Rome and from theArchbishop of Reims. InReims, he took the holy orders with papal consent, but he was killed soon after by hired assassins. His brother Duke Henry chose to conclude a peace agreement with the emperor but remained a bitter enemy.
Emperor Henry already was concerned with the deposition of the Welf supporter ArchbishopHartwig II of Bremen. He further had to arbitrate in a conflict in theMargraviate of Meissen on the eastern border of the Empire, where theWettin margraveAlbert I had to fend off the claims raised by his brotherTheoderic and Landgrave Hermann of Thuringia. Meanwhile, the opposition in the west took on a dramatic scale, when the dukes ofBrabant andLimburg joined forces with ArchbishopBruno III of Cologne. A massive confederacy against the emperor loomed ahead, including ArchbishopConrad of Mainz, Archchancellor of Germany, and DukeOttokar I of Bohemia, as well Henry's old rival Henry the Lion, the SwabianHouse of Zähringen, theEnglish Crown, and the pope, irritated by the killing of Albert of Louvain.[9]
Richard the Lionheart submits himself to Emperor Henry,Liber ad honorem Augusti, fol. 129R
At this stage, Henry had a stroke of good fortune when theBabenberg dukeLeopold V of Austria gave him his prominent prisoner,Richard the Lionheart, King of England, whom he had captured on his way back from the Third Crusade and held atDürnstein Castle. On 28 March 1193, Richard was handed over to the emperor inSpeyer and imprisoned atTrifels Castle, taking revenge for Richard's alliance with Tancred of Lecce. Ignoring his nearexcommunication by Pope Celestine III for imprisoning a former crusader, he held the English King for a ransom of 150,000 silver marks and officially declared a dowry of Richard's nieceEleanor, who was to marry Duke Leopold's sonFrederick. The oppositionprinces had to face the defeat of their mighty ally and to refrain from their plans to overthrow the Hohenstaufen dynasty.[12]
Backed by his mother Eleanor of Aquitaine, who successfully defended his interests against his rival brotherJohn, Count of Mortain and his ally King Philip of France, King Richard procured his release in exchange for the huge ransom, a further interest payment, and hisoath of allegiance to Henry. In turn the emperor under threat of military violence demanded the restitution of the French lands, which John had seized upon approval by Philip during Richard's absence. Henry not only gained another vassal and ally, he could also assume the role of a mediator betweenEngland andFrance. He and Richard were ceremoniously reconciled at theHoftag in Speyer during Holy Week 1194: the English king publicly regretted any hostilities, genuflected, and cast himself on the emperor's mercy. He was released and returned to England.[13]
At the same time, Henry settled the longstanding conflict with the Welf dynasty when he secured the marriage ofAgnes of Hohenstaufen, daughter of his half-uncle Count PalatineConrad, to Henry the Lion's son Henry of Brunswick, followed by a peace agreement in March 1194.

Meanwhile, the situation in Southern Italy had grown worse: After Henry's defeat at Naples, Tancred's brother-in-law CountRichard of Acerra had reconquered large parts of Apulia, and Tancred himself had reached the allowance of his claims by the pope. Henry was granted free passage in Northern Italy, having forged an alliance with the Lombard communes. In February 1194, Tancred of Lecce died, leaving as heir a young boy,William III, under the tutelage of his motherSibylla of Acerra. In May Emperor Henry, based on King Richard's ransom, again set out for Italy. He reached Milan at Pentecost and occupied Naples in August. He met little resistance and on 20 November 1194 enteredPalermo capital of Kingdom of Sicily and was crowned king on 25 December. On the next day his wife Constance, who had stayed back inIesi, gave birth to his only son and heirFrederick II, the future emperor and king of Sicily and Jerusalem.[9]
The young William and his mother Sibylla had fled toCaltabellotta Castle; he officially renounced the Sicilian kingdom in turn for theCounty of Lecce and thePrincipality of Capua. A few days after Henry's coronation, however, the royal family and several Norman nobles were accused of a coup attempt and arrested. Henry is said to have had William blinded and castrated, while many of his followers wereburned alive. Some, however, like the Siculo-GreekEugene of Palermo, transitioned into the new Hohenstaufen government with ease. William probably was deported toAltems (Hohenems) Castle in Swabia, where he died in captivity about 1198.
In March 1195 Henry held aHoftag inBari and appointed his wife Constance Sicilianqueen regnant, though with Henry's loyal vassalConrad of Urslingen, elevated to a hereditaryduke of Spoleto, asImperial vicar to secure the emperor's position in Southern Italy. He placed furtherministeriales in the Sicilian administration, like theTroia bishopWalter of Palearia who became chancellor. His loyal henchman Markward von Annweiler was appointed a duke ofRavenna, placing him in a highly strategic position to control the route to Sicily via the ItalianRomagna region and theApennines. Henry's younger brotherPhilip of Swabia was vested with the large estates of late margravineMatilda inTuscany. The emperor also felt strong enough to send home the Pisan and Genoese ships without giving their governments the promised concessions.[14]
The Sicilian kingdom added to Henry's personal and Imperial revenues an income without parallel in Europe. However, his aims to integrate Sicily into the Empire as a second power base of the Hohenstaufen dynasty were not realised during his lifetime. The negotiations with Pope Celestine III to approve the unification (unio regni ad imperium) in return of anothercrusade reached a deadlock. On the other hand, his beliefs of a universal rule according to thetranslatio imperii concept collided with the existence of theByzantine Empire, reflected in Henry's expansionist policies by the imposition of suzerainty over KingLeo I of Armenia and KingAimery of Cyprus.
In 1195 Henry's envoys inConstantinople raised claims to formerItalo-Norman possessions aroundDyrrachium (Durrës), one of the most important naval bases on the easternAdriatic coast, and pressed for a contribution to the planned crusade. Upon the deposition of EmperorIsaac II Angelos Henry openly threatened with an attack on Byzantine territory. He already evolved plans to betroth his younger brother Philip to Isaac's daughter PrincessIrene Angelina—deliberately or not—opening up a perspective to unite the Western and Eastern Empire under Hohenstaufen rule. According to the contemporary historianNiketas Choniates his legates were able to collecta large tribute from Isaac's brother and successorAlexios III but it was not paid before Henry's death.[15]
When an armistice between Pisa and theRepublic of Venice ended, the Pisans attacked Venetian ships in Marmora and carried out raids against theỉr premises in Constantinople. The matters escalated and the two sides went to war. The Byzantine emperorAlexios III Angelos was thought to be behind Pisan attacks. In 1197, Henry imposed a truce on them.[16][17] Previously, Pisa and Genoa had supported Henry's invasion of Italy while Venice chose to be neutral. But Henry granted Venice various rights in 1195 and 1197 while prevaricating over the more extensive privileges Pisa and Genoa claimed.[18][19][20] Henry's planned expansion against Thessaloniki and Constantinople, if it had happened, would have isolated Venice in its own gulf, and Venice was worrying that Alexios would rather submit to Henry than settle disgreements with Venice. Henry's death relieved both Venice and Constantinople of their worries. On the news of Henry's death, the Byzantine "German tax" was abolished.[21][22]
When Henry died, he was the most powerful monarch in Christendom, being Holy Roman Emperor, King of Germany, Burgundy, Italy, Sicily, feudal overlord of the Kings of England, Lesser Armenia and Cyprus, and tributary lord of Northern African princes.[23]
In summer 1195 Henry returned to Germany, in order to call for support to launch his crusade and to arrange his succession in the case of his death. However, he first again had to deal with the quarrels in the Wettin Margraviate of Meissen upon the death of Margrave Albert I. As Albert had tried to gain control over the adjacentPleissnerland, an Imperial Hohenstaufen territory, Henry took the occasion to deny the inheritance claims of the margrave's younger brother Theodoric and seized the Meissen territory for himself. In October he reconciled with Archbishop Hartwig of Bremen atGelnhausen and was able to obtain the support of numerous Saxon and Thuringian nobles for his crusade which was scheduled to begin on Christmas 1196.
His next aim was to make the imperial crownhereditary. Henry tried to secure the Imperial election of his son Frederick II as King of the Romans, which however met with objections raised by ArchbishopAdolf of Cologne. Spending the winter inHagenau Castle, the emperor and hisministeriales evolved the idea of a hereditary monarchy. Though they would have lost their right to elect the kings, the secular princes themselves wished to make their Imperial fiefs hereditary and to be inheritable by the female line as well, and Henry agreed to consider these demands. The emperor also bought the support of ecclesiastical princes by announcing that he would be willing to give up theJus Spolii and the right to receive recurring earnings from church lands during a period ofsede vacante. At the Diet ofWürzburg, held in March/April 1196, he managed to convince the majority of the princes to vote for his proposal. However, Archbishop Adolf of Cologne did not even put in an appearance and several princes, predominantly in Saxony and Thuringia, were still dissatisfied.[24]
While in July 1196 Henry proceeded to Burgundy and Italy in order to negotiate with Pope Celestine III, the resistance in Germany grew. At the following diet atErfurt in October, a majority of the princes rejected the emperor's plans. Furthermore, the Pope, still concerned in view of the Hohenstaufen rule over Sicily, broke off the talks. Nevertheless, on Christmas Henry's son Frederick II was elected King of the Romans in Frankfurt.
At the same time, the emperor stayed inCapua, where he had Count Richard of Acerra, held in custody by hisministerialisDipold von Schweinspeunt, cruelly executed. He entered Sicily in March 1197 and applied himself to prepare his crusade inMessina.
Soon after, the transition to Hohenstaufen's rule in Italy spurred revolts, especially aroundCatania and southern Sicily, which his German soldiers led by Markward of Annweiler andHenry of Kalden suppressed mercilessly. The rebels even sought to make CountJordan of Bovino king in Henry's place. Some contemporary Germans (who were hostile to Empress Constance) even accused her of directly collaborating with the rebels, even though recent research like the work of Theo Kölzer shows that this was unlikely. Kölzer opines though that Henry's "discipline methods" in Sicily had put a dent on the relationship between wife and husband, and it was possible that Constance passively tolerated the rebels.[25] In the midst of preparations Henry fell ill withchills while hunting nearFiumedinisi and on 28 September died, likely ofmalaria (contracted since the siege of Napoli in 1191 and had never completely healed), in Messina,[26] although some immediately accused Constance of poisoning him.[27] His wife Constance had him buried at Messina; in 1198, his mortal remains were transferred toPalermo Cathedral. Various items were removed from Henry VI's grave in the late eighteenth century, some of which are now in theBritish Museum in London. They include the remains of a shoe, a head band and an ornatesilk textile that originally wrapped the body.[28]
Henry's minor son Frederick II was to inherit both the Kingdom of Sicily and the Imperial crown. However, a number of princes around Archbishop Adolf of Cologne elected the WelfOtto of Brunswick, son of Henry the Lion, anti-king. To defend the claims of the Hohenstaufen dynasty, Frederick's uncle Philip of Swabia had himself elected King of the Romans in March 1198. TheGerman throne quarrel lasted nearly twenty years, until Frederick was again elected king in 1212 and Otto, defeated by theFrench in the 1214Battle of Bouvines and abandoned by his former allies, finally died in 1218.[9]
During his rule in Germany, Henry moved from oneKaiserpfalz residence to another or—to a lesser extent—stayed atPrince-bishop's sees in the tradition of the medieval itinerant kingship. He concentrated on theFranconian core locations of his kingdom, while theBavarian andSaxon lands were less subject to the central authority. His travel routes through Germany as well as his campaigns in Italy are documented by numerous deeds he issued year by year.
While being overshadowed by the legendary figures of his father and son, the two Fredericks, Henry is generally considered to be a talented leader and his reign is also considered to be remarkable. Koenigsberger calls him an "immensely able politician", who was able to break the alliance of Western kings, who combined their forces against his great power. But the empire, depending much on the person of the ruler, like other mediaeval empires, collapsed when he died.[29][30]
Later historians stressed the fact of Henry's early death and the succeeding throne quarrel as a stroke of fate and a major setback for the development of a Germannation state begun under his father Frederick Barbarossa. On the other hand, the emperor's stern measures in Sicily earned him the reputation of a cruel and merciless ruler. Present-day historical research classifies Henry as a man of his time; though a capable ruler he had to cope with the centrifugal forces while at the same time he overstretched the Hohenstaufen realm to an extent that finally could not be kept together.
