. For a quarter of a century following the death of Henry V in 1125, the German monarchy was largely a nominal title with no real power. The king was chosen by the princes, was given no resources outside those of his own duchy, and he was prevented from exercising any real authority or leadership in the realm. The royal title was furthermore passed from one family to another to preclude the development of any dynastic interest in the German crown. When Frederick I of Hohenstaufen was chosen as king in 1152, royal power had been in effective abeyance for over twenty-five years, and to a considerable degree for more than eighty years. The only real claim to wealth lay in the rich cities of northern Italy, which were still within the nominal control of the German king. The Salian line had died out with the death of Henry V in 1125. The German princes refused to give the crown to his nephew, the duke of Swabia, for fear he would try to regain the imperial power held by Henry V. Instead, they chose

, would not be appeased, however, remaining an implacable enemy of the Hohenstaufen monarchy. Barbarossa had the duchies of Swabia and Franconia, the force of his own personality, and very little else to construct an empire. The Germany that Frederick tried to unite was a patchwork of more than 1,600 individual states, each with its own prince. A few of these, such as Bavaria and Saxony, were large. Many were too small to pinpoint on a map. The titles afforded to the German king were "Caesar", "Augustus", and "Emperor of the Romans". By the time Frederick would assume these, they were little more than propaganda slogans with little other meaning. Frederick was a pragmatist who dealt with the princes by finding a mutual self-interest. Unlike

, Frederick did not attempt to end medieval feudalism, but rather tried to restore it, though this was beyond his ability. The great players in the German civil war had been the Pope, Emperor, Ghibellines and the Guelfs, but none of these had emerged as the winner.

. As a sign of good faith, Frederick dismissed the ambassadors from the revived Roman Senate, and Imperial forces suppressed the republicans. Arnold was captured and hanged for treason and rebellion. Despite his unorthodox teaching concerning theology, Arnold was not charged with heresy. As Frederick approached the gates of Rome, the Pope advanced to meet him. At the royal tent the king received him, and after kissing the pope's feet, Frederick expected to receive the traditional kiss of peace. Frederick had declined to hold the Pope's stirrup while leading him to the tent, however, so Adrian refused to give the kiss until this protocol had been complied with. Frederick hesitated, and Adrian IV withdrew; after a day's negotiation, Frederick agreed to perform the required ritual, reportedly muttering, "''Pro Petro, non Adriano'' – For Peter, not for Adrian." Rome was still in an uproar over the fate of Arnold of Brescia, so rather than marching through the streets of Rome, Frederick and Adrian retired to the Vatican.

Second, Third and Fourth Italian Campaigns: 1158–1174

As a result, the issue was not resolved at that time. The political result of the struggle with Pope Alexander was an alliance formed between the Norman state of Sicily and Pope Alexander III against Frederick. In the meantime, Frederick had to deal with another rebellion at Milan, in which the city surrendered on 6 March 1162; much of it was destroyed three weeks later on the emperor's orders.

), which threatened to destroy the Imperial army and drove the emperor as a fugitive to Germany, where he remained for the ensuing six years.

Frederick did not forgive Henry the Lion for refusing to come to his aid in 1176. By 1180, Henry had successfully established a powerful and contiguous state comprising Saxony, Bavaria, and substantial territories in the north and east of Germany. Taking advantage of the hostility of other German princes to Henry, Frederick had Henry tried in absentia by a court of bishops and princes in 1180, declared that imperial law overruled traditional German law, and had Henry stripped of his lands and declared an outlaw. He then invaded Saxony with an imperial army to force his cousin to surrender. Henry's allies deserted him, and he finally had to submit to Frederick at an Imperial Diet in

in Normandy before being allowed back into Germany. He finished his days in Germany, as the much-diminished Duke of Brunswick. Frederick's desire for revenge was sated. Henry the Lion lived a relatively quiet life, sponsoring arts and architecture. Frederick's victory over Henry did not gain him as much in the German feudalistic system as it would have in the English feudalistic system. While in England the pledge of fealty went in a direct line from overlords to those under them, the Germans pledged oaths only to the direct overlord, so that in Henry's case, those below him in the feudal chain owed nothing to Frederick. Thus, despite the diminished stature of Henry the Lion, Frederick did not gain his allegiances. Frederick was faced with the reality of disorder among the German states, where continuous civil wars were waged between pretenders and the ambitious who wanted the crown for themselves. Italian unity under German rule was more myth than truth. Despite proclamations of German hegemony, the pope was the most powerful force in Italy. When Frederick returned to Germany after his defeat in northern Italy, he was a bitter and exhausted man. The German princes, far from being subordinated to royal control, were intensifying their hold on wealth and power in Germany and entrenching their positions. There began to be a generalized social desire to "create greater Germany" by conquering the Slavs to the east. Although the Italian city states had achieved a measure of independence from Frederick as a result of his failed fifth expedition into Italy, the emperor had not given up on his Italian dominions. In 1184, he held a massive celebration, the Diet of Pentecost, when his two eldest sons were knighted, and thousands of knights were invited from all over Germany. While payments upon the knighting of a son were part of the expectations of an overlord in England and France, only a "gift" was given in Germany for such an occasion. Frederick's monetary gain from this celebration is said to have been modest. Later in 1184, Frederick again moved into Italy, this time joining forces with the local rural nobility to reduce the power of the Tuscan cities. In 1186, he engineered the marriage of his son Henry to

Pope Urban III died shortly after, and was succeeded by Pope Gregory VIII, who even as Papal Chancellor had pursued a more conciliatory line with the Emperor than previous popes and was more concerned with troubling reports from the Holy Land than with a power struggle with Barbarossa.


Third Crusade

Around 23 November 1187, Frederick received letters that had been sent to him from the rulers of the

On 27 March 1188, at the Curia Christi, Diet of Mainz, the archbishop of Cologne submitted to Frederick. Bishop of Würzburg, Godfrey of Spitzenberg, preached a crusade sermon and Frederick asked the assembly whether he should take the cross. At the universal acclaim of the assembly, he took the crusader's vow. His second son, the duke of Swabia, followed suit. The eldest, Henry VI, was to remain behind in Germany as regent. At Mainz Frederick proclaimed a "general expedition against the pagans". He set the period of preparation as 17 April 1188 to 8 April 1189 and scheduled the army to assemble at

on 23 April 1189. At Strasbourg, Frederick had imposed a small tax on the History of the Jews in Germany, Jews of Germany to fund the crusade. He also put the Jews under his protection and forbade anyone to preach against the Jews. When mobs threatened the Jews of Mainz on the eve of the assembly in March, Frederick sent the imperial marshal Henry of Kalden to disperse them. Rabbi Moses then met with the emperor, which resulted in an imperial edict threatening maiming or death for anyone who maimed or killed a Jew. On 29 March, Frederick and the rabbi rode through the streets together. Frederick successfully prevented a repeat of the Rhineland massacres, massacres that had accompanied the First Crusade and Second Crusade in Germany. Because Frederick had signed a treaty of friendship with Saladin in 1175, he felt it necessary to give Saladin notice of the termination of their alliance. On 26 May 1188, he sent Count Henry II of Dietz to present an ultimatum to Saladin. A few days after Christmas 1188, Frederick received Hungarian, Byzantine, Serbian and Seljuk envoys in Nuremberg. The Hungarians and Seljuks promised provisions and safe-conduct to the crusaders. The envoys of Stefan Nemanja, grand prince of Serbia, announced that their prince would receive Frederick in Niš. Only with difficulty was an agreement reached with the Byzantine envoy, John Kamateros (logothetes tou dromou), John Kamateros. Frederick sent a large embassy ahead to make preparations in Byzantium.

, Frederick formally and symbolically accepted the staff and scrip of a pilgrim and set out. His crusade was "the most meticulously planned and organized" up to that time. According to one source written in the 1220s, Frederick organized a grand army of 100,000 men (including 20,000 knights) and set out on the overland route to the Holy Land;J. Phillips, ''The Fourth Crusade and the Sack of Constantinople'', 66 This number is believed to be inaccurate and modern estimates using contemporary sources place the size of his army at 12,000–15,000 men, including 3,000–4,000 knights.Konstam, ''Historical Atlas of the Crusades'', 162 The Crusaders passed through Kingdom of Hungary, Hungary, Grand Principality of Serbia, Serbia, and Second Bulgarian Empire, Bulgaria before entering Byzantine territory. Matters were complicated by a secret alliance between the Emperor of Constantinople, Isaac II Angelos, and Saladin, warning of which was supplied by a note from Sibylla, Queen of Jerusalem, Sibylla, ex-Queen of Jerusalem. While in Hungary, Barbarossa personally asked the Hungarian Géza, son of Géza II of Hungary, Prince Géza, brother of King Béla III of Hungary, to join the Crusade. The king agreed, and a Hungarian army of 2,000 men led by Géza escorted the German emperor's forces. Later on, Frederick camped in Philippopolis (Thrace), Philippopolis, then in

in the autumn of 1189 to avoid winter climate in Anatolia, in the meantime, he received imprisoned German emissaries who were held in Constantinople, and exchanged hostages with Isaac II, as a guarantee that the crusaders do not sack local settlements until they depart the Byzantine territory. In March 1190, Frederick left Adrianople to Gallipoli at the Dardanelles to embark to Asia Minor. The armies coming from western Europe pushed on through Anatolia, where they were victorious at the Battle of Philomelion (1190), Battle of Philomelium and defeated the Turks in the Battle of Iconium (1190), Battle of Iconium, eventually reaching as far as Cilician Armenia. The approach of Barbarossa's victorious German army greatly concerned Saladin, who was forced to weaken his force at the Siege of Acre (1189–1191), Siege of Acre and send troops to the north to block the arrival of the Germans.


Death and burials

Emperor Frederick Barbarossa opted on the local Armenians' advice to follow a shortcut along the Saleph river. Meanwhile, the army started to traverse the mountain path. On 10 June 1190, he drowned near Silifke Castle in the Saleph river. There are several conflicting accounts of the event: * According to "History of the Expedition of the Emperor Frederick, Ansbert", against everyone's advice, the emperor chose to swim across the river and was swept away by the current. * Another account recorded that Frederick was thrown from his horse while crossing the river, weighed down by his armour, and drowned. * According to the chronicler Ibn al-Athir, "the king went down to the river to wash himself and was drowned at a place where the water was not even up to his waist. Thus God saved us from the evil of such a man". * The writer of the ''Letter on the Death of the Emperor Frederick'', a churchman who accompanied the crusader forces, reported that "after the many and terrible exertions that he [Frederick I] had undergone in the previous month and more, he decided to bathe in that same river, for he wanted to cool down with a swim. But by the secret judgment of God there was an unexpected and lamentable death and he drowned." Frederick who liked to swim, as he went to bathe with Otto I, Duke of Bavaria, Otto of Wittelsbach in the Adriatic, might have been exhausted from weeks of marching, hence he was fatally affected by the very hot summer in Anatolia. If the writer was Godfrey of Spitzenberg, Bishop of Würzburg, who was a close confidante to Frederick, the report would be the most plausible account of what happened, since he might have witnessed the emperor's death. Jacques de Vitry, a historian of the Crusades, outlined Frederick's endeavors and Saladin's dilemma, in which he reported: Frederick's death caused several thousand German soldiers to leave the force and return home through the Cilician and Syrian ports. The German-Hungarian army was struck with an onset of disease near Antioch, weakening it further. Only 5,000 soldiers, a third of the original force, arrived in

Hence, his flesh was interred in the Church of Saint Peter in Antioch, his bones in the cathedral of Tyre, and his heart and inner organs in Saint Paul's Church, Tarsus, Saint Paul's Church, Tarsus, Mersin, Tarsus. The unexpected demise of Frederick left the Crusader army under the command of the rivals Philip II and Richard I of England, Richard, who had traveled to Palestine (region), Palestine separately by sea, and ultimately led to its dissolution. Richard continued to the East where he fought Saladin, winning territories along the shores of Palestine, but ultimately failed to win the war by conquering Jerusalem itself before he was forced to return to his own territories in north-western Europe, known as the Angevin Empire. He returned home after he signed the Treaty of Ramla agreeing that Jerusalem would remain under Muslim control while allowing unarmed Christian pilgrims and traders to visit the city. The treaty also reduced the Kingdom of Jerusalem, Latin Kingdom to a geopolitical coastal strip extending from Tyre to Jaffa.


Frederick and the Justinian code

The increase in wealth of the trading cities of northern Italy led to a revival in the study of the Justinian Code, a Latin legal system that had become extinct centuries earlier. Legal scholars renewed its application. It is speculated that
Pope Gregory VII Pope Gregory VII ( la, Gregorius VII; 1015 – 25 May 1085), born Hildebrand of Sovana ( it, Ildebrando di Soana), was head of the Catholic Church and ruler of the Papal States from 22 April 1073 to his death in 1085. He is venerated as a saint ...
personally encouraged the Justinian rule of law and had a copy of it. The historian Norman Cantor described Corpus Juris Civilis (Justinian Body of Civil Law) as "the greatest legal code ever devised". It envisaged the law of the state as a reflection of natural moral law, the principle of rationality in the universe. By the time Frederick assumed the throne, this legal system was well established on both sides of the Alps. He was the first to use the availability of the new professional class of lawyers. The Civil Law allowed Frederick to use these lawyers to administer his kingdom in a logical and consistent manner. It also provided a framework to legitimize his claim to the right to rule both Germany and northern Italy. In the old days of Henry IV and Henry V, the claim of divine right of kings had been severely undermined by the
Investiture controversy The Investiture Controversy, also called Investiture Contest (German: ''Investiturstreit''; ), was a conflict between the Church and the state in medieval Europe over the ability to choose and install bishops ( investiture) and abbots of mona ...
. The Church had won that argument in the common man's mind. There was no divine right for the German king to also control the church by naming both bishops and popes. The institution of the Justinian code was used, perhaps unscrupulously, by Frederick to lay claim to divine powers. In Germany, Frederick was a political realist, taking what he could and leaving the rest. In Italy, he tended to be a romantic reactionary, reveling in the antiquarian spirit of the age, exemplified by a revival of classical studies and Roman law. It was through the use of the restored Justinian code that Frederick came to view himself as a new Roman emperor. Roman law gave a rational purpose for the existence of Frederick and his imperial ambitions. It was a counterweight to the claims of the Church to have authority because of divine revelation. The Church was opposed to Frederick for ideological reasons, not the least of which was the humanist nature found in the revival of the old Roman legal system. When Pepin the Short sought to become king of the Franks in the 8th century, the church needed military protection, so Pepin found it convenient to make an ally of the pope. Frederick, however, desired to put the pope aside and claim the crown of old Rome simply because he was in the likeness of the great emperors of old, who tended to have a domineering role over the church, Caesaropapism. Pope Adrian IV was naturally opposed to this view and undertook a vigorous propaganda campaign designed to diminish Frederick and his ambition. To a large extent, this was successful.


Economic policy

Frederick did little to encourage economic development in Germany prior to the autumn of 1165. In that year he visited the lower Rhineland, the most economically advanced region in Germany. He had already travelled to northern Italy, the most economically advanced region in the Empire, three times. From 1165 on, Frederick pursued economic policies to encourage growth and trade. There is no question that his reign was a period of major economic growth in Germany, but it is impossible now to determine how much of that growth was owed to Frederick's policies. The number of mints in Germany increased ninefold in the reign of Frederick and his son Henry, from about two dozen mints at the start of his reign to 215 mints in 1197 and from a mere two royal mints to 28. Frederick himself established at least twelve royal mints, including those of Aachen, Donauwörth, Ulm, Haguenau, Duisburg, Kaiserswerth, Frankfurt, Gelnhausen and Dortmund. He also granted privileges exempting the merchants of Aachen, Gelnhausen, Haguenau, Monza, Rome, Pisa and Venice from all tolls within the Empire.

Charismatic leader

Otto of Freising Otto of Freising ( la, Otto Frisingensis; c. 1114 – 22 September 1158) was a German churchman of the Cistercian order and chronicled at least two texts which carries valuable information on the political history of his own time. He was Otto I ...
, Frederick's uncle, wrote an account of his reign entitled ''Gesta Friderici I imperatoris'' (Deeds of the Emperor Frederick), which is considered to be an accurate history of the king. Otto's other major work, the ''Chronica sive Historia de duabus civitatibus'' (''Chronicle or History of the Two Cities'') had been an exposition of the ''Civitas Dei'' (''The City of God'') of St. Augustine of Hippo, full of Augustinian negativity concerning the nature of the world and history. His work on Frederick is of opposite tone, being an optimistic portrayal of the glorious potentials of imperial authority. Otto died after finishing the first two books, leaving the last two to Rahewin, his provost. Rahewin's text is in places heavily dependent on classical precedent. For example, Rahewin's physical description of Frederick reproduces word-for-word (except for details of hair and beard) a description of another monarch, Theodoric II written nearly eight hundred years earlier by Sidonius Apollinaris: Frederick's charisma led to a fantastic juggling act that, over a quarter of a century, restored the imperial authority in the German states. His formidable enemies defeated him on almost every side, yet in the end he emerged triumphant. When Frederick came to the throne, the prospects for the revival of German imperial power were extremely thin. The great German princes had increased their power and land holdings. The king had been left with only the traditional family domains and a vestige of power over the bishops and abbeys. The backwash of the Investiture controversy had left the German states in continuous turmoil. Rival states were in perpetual war. These conditions allowed Frederick to be both warrior and occasional peace-maker, both to his advantage.


Legend

Frederick is the subject of many legends, including that of a King asleep in mountain, Kyffhäuser legend. Legend says he is not dead, but asleep with his knights in a cave in the Kyffhäuser mountains in Thuringia or Mount Untersberg at the border between Bavaria, Germany, and Salzburg, Austria, and that when the ravens cease to fly around the mountain he will awake and restore Germany to its ancient greatness. According to the story, his red beard has grown through the table at which he sits. His eyes are half closed in sleep, but now and then he raises his hand and sends a boy out to see if the ravens have stopped flying. A similar story, set in Sicily, was earlier attested about his grandson, Frederick II, Holy Roman Emperor, Frederick II. To garner political support the German Empire built atop the Kyffhäuser the Kyffhäuser Monument, which declared Kaiser Wilhelm I the reincarnation of Frederick; the 1896 dedication occurred on 18 June, the day of Frederick's coronation. In medieval Europe, the Golden Legend became refined by Jacopo da Voragine. This was a popularized interpretation of the Biblical end of the world. It consisted of three things: (1) terrible natural disasters; (2) the arrival of the Antichrist; (3) the establishment of a good king to combat the anti-Christ. These millennial fables were common and freely traded by the populations on Continental Europe. Eschatology, End-time accounts had been around for thousands of years, but entered the Christian tradition with the writings of the Apostle Peter. German propaganda played into the exaggerated fables believed by the common people by characterizing Frederick Barbarossa and Frederick II as personification of the "good king". Another legend states that when Barbarossa was in the process of seizing Milan in 1158, his wife, the Empress Beatrice, was taken captive by the enraged Milanese and forced to Parading on donkey, ride through the city on a donkey in a humiliating manner. Some sources of this legend indicate that Barbarossa implemented his revenge for this insult by forcing the magistrates of the city to remove a fig from the anus of a donkey using only their teeth. Another source states that Barbarossa took his wrath upon every able-bodied man in the city, and that it was not a fig they were forced to hold in their mouth, but excrement from the donkey. To add to this debasement, they were made to announce, ''"Ecco la fica"'' (meaning "behold the fig"), with the feces still in their mouths. It used to be said that the insulting gesture (called fico), of holding one's fist with the thumb in between the middle and forefinger came by its origin from this event. Frederick's legend was further reinforced in the early twentieth century, when Adolf Hitler named Nazi Germany's Operation Barbarossa, invasion of the Soviet Union after him.


Historiography

Cultural depictions of Frederick I, Holy Roman Emperor#Historiography, Scholarly evaluations of Frederick began in the nineteenth century, but have been hampered by the unfortunate deaths of key researchers who did not have the chance to complete their works (such as Henry Simonsfeld who died in 1913, Wilhelm von Giesebrecht who died in 1889 and Johannes Laudage who died in an accident in 2008). Nevertheless, the two volumes about Frederick (that focus on his relationship with the Welfs and the Papacy) in Wilhelm von Giesebrecht's ''Geschichte der Deutschen Kaiserzeit'' (1855–88), completed by his student Bernhard von Simson in 1895, later became the scholarly standard work on the emperor's life. In 1975, Frederick's charters were published. This and the postwar abandonment of the Kyffhäuser myth have led to the publications of several new biographies. The notable recent authorities among German-speaking historians include Ferdinand Opll, Johannes Laudage, and Knut Görich. Opll's ''Friedrich Barbarossa'' (1990) presents the emperor as a pragmatic leader with a capacity of adaptation and recovery after defeat. Laudage investigates the important role of the concept of honour in Frederick's decisions while explaining the far-reaching visions of the emperor and his advisers, while Görich (who also emphasizes the honour, or ''honor imperii'' factor) questions whether traditional researchers have overemphasized the intentional side of Frederick's politics and instead highlights his flexibility and consensus-building capability as a leader. In Italy, the scholarly attention towards Frederick's person and his reign is also considerable, with notable contributions including Franco Cardini's sympathetic 1985 biography or the 1982 work ''Federico Barbarossa nel dibattito storiografico in Italia e in Germania'', edited by Manselli and Riedmann, considered by Schumann to be a definite synthesis of non-nationally oriented historiography approaches (combining German and Italian research results) of the last forty years.


Artistic depictions

* In Victor Hugo's romantic play ''Les Burgraves'' (1843), Frederick (as character Frédéric de Hohenstaufen) returns many years after he was presumed dead, as expected by some medieval legends. * Cyrus Townsend Brady's ''Hohenzollern; a Story of the Time of Frederick Barbarossa'' (1901) begins with a dedication to "the descendants of the great Germanic race who in Europe, in America, and in the Far East rule the world". * ''Land of Unreason'' (1941), by L. Sprague de Camp and Fletcher Pratt, mentions the castle of the Kyffhäuser. * Umberto Eco's novel ''Baudolino'' (2000) is set partly at Frederick's court, and also deals with the mystery of Frederick's death. The imaginary hero, Baudolino, is the Emperor's adopted son and confidant. * In the 2009 movie ''Barbarossa (film), Barbarossa'' (also titled ''Sword of War'' and ''Barbarossa: Siege Lord''), Barbarossa is one of the main characters, played by Rutger Hauer. * The German broadcaster Deutsche Welle (DW) 2018 documentary (The Germans), featured Frederick I in its 3rd of 6 episodes. * Recently, to commemorate the emperor, the Supply Battalion 131 (called "Battalion Barbarossa") of the Kyffhäuser barracks () built
