Frederick Barbarossa Timeline

Through the Privilegium Minus, issued at the imperial diet at Regensburg, Frederick elevated Austria to a duchy independent of Bavaria, granted to the Babenberg dynasty, reshaping the political geography of southeastern Europe.

In 1157 Frederick led an expedition against Duke Bolesław IV of Poland, forcing him to do homage and pay tribute, reasserting imperial influence over Poland which had lapsed under his predecessors.

Following Adrian IV's death, a papal schism broke out. Frederick supported antipopes against Alexander III, plunging empire and papacy into conflict that dominated much of his reign.

Frederick promoted the canonization of Charlemagne, his great model, by the antipope he backed. The act emphasized his self-image as heir to the Carolingian empire and boosted imperial prestige despite lacking universal recognition.

Frederick had his five-year-old son Henry crowned King of the Romans at Aachen, securing dynastic succession early and ensuring continuity of Hohenstaufen rule.

Frederick formally reconciled with Pope Alexander III at Venice, ending the papal schism. He knelt before the pope in a gesture symbolizing the end of nearly two decades of church-state conflict.

Pope Alexander III convened the Third Lateran Council, which condemned the antipopes and reformed the church. Its decrees further solidified the papal position that Frederick had been forced to accept.

After Henry the Lion refused to join the Italian campaigns, Frederick convened diets that declared him deposed, confiscating his Saxon and Bavarian duchies and redistributing them to loyal vassals, breaking the power of the Welfs.

Frederick arranged the marriage of his son Henry to Constance, aunt and heiress of King William II of Sicily, laying the groundwork for the eventual union of the imperial crown with the Norman kingdom of Sicily.

After Saladin destroyed the crusader army at Hattin and captured Jerusalem, Pope Gregory VIII called for a new crusade. Frederick, then nearly seventy, took the cross as one of the first European monarchs to respond.

At the 'Court of Jesus' in Mainz, thousands of knights took the crusader vow alongside the emperor. Frederick spent the following year raising funds, securing peace in Europe, and preparing a massive army.

Frederick led what may have been the largest crusading army ever assembled out of Regensburg on the overland route through Hungary, Byzantium, and Anatolia, numbering possibly tens of thousands of men.

Despite harassment by Seljuk forces and treacherous Byzantine diplomacy, Frederick stormed and captured the Seljuk capital of Iconium in Konya, a remarkable victory late in the arduous march through Asia Minor.

While crossing the Saleph River (Göksu) in Cilicia, possibly to bathe, the aged emperor drowned. His death shattered the morale of his army; most German crusaders returned home or died, though a remnant reached the siege of Acre under his son.

German legend held that Barbarossa did not die but sleeps beneath Kyffhäuser mountain, awaiting Germany's hour of need. The myth became a powerful national symbol, inspiring art and politics into the 19th century.
