History of germany

Conversion of the Saxons: 772-804

North of the Alps Charlemagne extends his territory eastwards to include Bavaria, but his main efforts within Germany are directed against the Saxons. 

The Saxons, restless Germanic tribesmen, have long plagued the settled Frankish territories by raiding from their forest sanctuaries. Charlemagne the emperor is harmed by their depredations; Charlemagne the Christian is outraged by their pagan practices. From 772 he wages ferocious war against them, beginning with the destruction of one of their great shrines and its sacred central feature - the Irminsul or 'pillar of the world', a massive wooden column believed to support the universe. 
It takes Charlemagne thirty years to subdue the Saxons; not until 804 are they finally transformed into settled Christians within his empire. It has been a brutal process. Charlemagne's method is military conquest followed by forced conversion and the planting of missionary outposts, usually in the form of bishoprics. In his book of rules, the official punishment for refusing to be baptized is death. 
The chronicles record that on one day some 4500 reluctant Saxons are executed for not worshipping the right god. 


Holy Roman Emperor: 800

In 799, for the third time in half a century, a pope is in need of help from the Frankish king. After being physically attacked by his enemies in the streets of Rome (their stated intention is to blind him and cut out his tongue, to make him incapable of office), Leo III makes his way through the Alps to visit Charlemagne at Paderborn. 

It is not known what is agreed, but Charlemagne travels to Rome in 800 to support the pope. In a ceremony in St Peter's, on Christmas Day, Leo is due to anoint Charlemagne's son as his heir. But unexpectedly (it is maintained), as Charlemagne rises from prayer, the pope places a crown on his head and acclaims him emperor. 
Charlemagne expresses displeasure but accepts the honour. The displeasure is probably diplomatic, for the legal emperor is undoubtedly the one in Constantinople. Nevertheless this public alliance between the pope and the ruler of a confederation of Germanic tribes now reflects the reality of political power in the west. And it launches the concept of the new Holy Roman Empire which will play an important role throughout the Middle Ages. 
The Holy Roman Empire only becomes formally established in the next century. But it is implicit in the title adopted by Charlemagne in 800: 'Charles, most serene Augustus, crowned by God, great and pacific emperor, governing the Roman empire.'
