Third Sacred War
The Third Sacred War (356–346 BC) was fought between the forces of the Delphic Amphictyonic League, principally represented by Thebes, and latterly by Philip II of Macedon, and the Phocians. The war was caused by a large fine imposed in 357 BC on the Phocians by the Amphictyonic League (dominated at that moment by Thebes), for the offense of cultivating sacred land; refusing to pay, the Phocians instead seized the Temple of Apollo in Delphi, and used the accumulated treasures to fund large mercenary armies. Thus, although the Phocians suffered several major defeats, they were able to continue the war for many years, until eventually all parties were nearing exhaustion. Philip II used the distraction of the other states to increase his power in northern Greece, in the process becoming ruler of Thessaly. In the end, Philip's growing power, and the exhaustion of the other states, allowed him to impose a peaceful settlement of the war, marking a major step in the rise of Macedon to pre-eminence in Ancient Greece.
Frederick I, Holy Roman Emperor
In 1164 Frederick took what are believed to be the relics of the "Biblical Magi" (the Wise Men or Three Kings) from the Basilica di Sant'Eustorgio in Milan and gave them as a gift (or as loot) to the Archbishop of Cologne, Rainald of Dassel. The relics had great religious significance and could be counted upon to draw pilgrims from all over Christendom. Today they are kept in the Shrine of the Three Kings in the Cologne cathedral. After the death of the antipope Victor IV, Frederick supported antipope Paschal III, but he was soon driven from Rome, leading to the return of Pope Alexander III in 1165.
In the meantime Frederick was focused on restoring peace in the Rhineland, where he organized a magnificent celebration of the canonization of Charles the Great (Charlemagne) at Aachen, under the authority of the antipope Paschal III. Concerned over rumours that Alexander III was about to enter into an alliance with the Byzantine Emperor Manuel I, in October 1166 Frederick embarked on his fourth Italian campaign, hoping as well to secure the claim of Paschal III and the coronation of his wife Beatrice as Holy Roman Empress. This time, Henry the Lion refused to join Frederick on his Italian trip, tending instead to his own disputes with neighbors and his continuing expansion into Slavic territories in northeastern Germany. In 1167 Frederick began besieging Ancona, which had acknowledged the authority of Manuel I; at the same time, his forces achieved a great victory over the Romans at the Battle of Monte Porzio. Heartened by this victory, Frederick lifted the siege of Ancona and hurried to Rome, where he had his wife crowned empress and also received a second coronation from Paschal III. Unfortunately, his campaign was halted by the sudden outbreak of an epidemic (malaria or the plague), which threatened to destroy the Imperial army and drove the emperor as a fugitive to Germany, where he remained for the ensuing six years. During this period, Frederick decided conflicting claims to various bishoprics, asserted imperial authority over Bohemia, Poland, and Hungary, initiated friendly relations with Manuel I, and tried to come to a better understanding with Henry II of England and Louis VII of France. Many Swabian counts, including his cousin the young Duke of Swabia, Frederick IV, died in 1167, so he was able to organize a new mighty territory in the Duchy of Swabia under his reign in this time. Consequently, his younger son Frederick V became the new Duke of Swabia in 1167, while his eldest son Henry was crowned King of the Romans in 1169, alongside his father who also retained the title.
