Frequently asked questions

Frederick Barbarossa (1122-1190) was emperor of the Holy Roman Empire from 1155 until his death. The key thing to remember is that he embodies the struggle between imperial power and the papacy in the High Middle Ages. A member of the Hohenstaufen dynasty, he sought to restore imperial authority in Italy against the Lombard communes and the pope, while also leading a crusade. Less a mere conqueror than the builder of a “sacred” empire, he shaped his era through his legal reforms and major conflicts, until his death by drowning in 1190.

Works & Achievements

Proclamation of the Sacrum Imperium (Holy Empire) (c. 1157)

Frederick adds the adjective “holy” to the Empire, asserting that its dignity comes directly from God, without depending on the pope's consecration.

Constitutions of Roncaglia (1158)

Codification of the emperor's regalian rights in Italy, with the help of the jurists of Bologna; an attempt to ground imperial authority in Roman law.

Destruction then rebuilding of the Lombard order (1162)

The razing of Milan illustrates his determination to subdue the communes; he would ultimately fail to bring them lastingly to heel.

Peace of Venice with Pope Alexander III (1177)

End of the schism and reconciliation with the papacy after years of supporting antipopes, restoring religious peace to the Empire.

Peace of Constance (1183)

A compromise recognizing the autonomy of the Lombard cities while maintaining the emperor's formal sovereignty: a model of political balance.

Hohenstaufen-Sicily marriage policy (1186)

The marriage of his son Henry to Constance of Sicily, paving the way for the union of the Holy Empire and the Norman kingdom of Sicily under his descendants.

Anecdotes

His nickname “Barbarossa” (meaning “Redbeard” in Italian) was given to him by the inhabitants of the Italian cities because of his flaming red beard. In Germany, he was rather called “Rotbart”, which means the same thing. The Italian nickname stuck because it was in Italy that he led his most memorable campaigns.

In 1176, at the Battle of Legnano, the army of Frederick's knights was crushed by the foot militias of the Lombard League. For a moment the emperor was believed dead on the battlefield: he reappeared several days later in Pavia, to everyone's astonishment. This defeat forced him to recognize the autonomy of the Italian communes.

In 1190, during the Third Crusade, Frederick drowned while crossing the Saleph River (today's Göksu, in Turkey), perhaps the victim of a heart attack in the icy water. His sudden death threw the immense German army into disarray, and most of it turned back without ever reaching Jerusalem.

A German legend tells that Barbarossa never truly died, but lies asleep in a cave within the Kyffhäuser mountain, his red beard growing through the stone table. On the day the ravens stop circling the mountain, he will awaken to restore Germany to greatness.

In 1155, in order to be crowned emperor in Rome, Frederick at first refused to hold the stirrup of Pope Adrian IV's horse, a symbolic gesture of submission. The pope then withheld the kiss of peace. After two days of tension, Frederick finally gave in and performed the rite, showing just how much every ceremonial gesture was a matter of power.

We grant to you, cities of the Lombard League, the regalian rights and the customs that you have exercised, both within the towns and outside them; you shall elect your consuls, save for the oath of fidelity owed to the Empire.

Know that, by divine favor and the unanimous consent of the princes, we have been raised to the summit of the kingdom, and that we are striving to restore the honor of the Empire to its ancient dignity.

Key Places
