The center of the Frankish kingdom was in the northeast of France today, and later it spread to the whole of France and its surrounding areas. From the 6th century to the 8th century, the feudal system of the Frankish Kingdom was relatively consolidated, and during Charlemagne's rule, it expanded its territory on a large scale.
Charlemagne was a typical medieval knight, burly and full of energy. He didn't know about fatigue and illness until his later years. He was in office for nearly 50 years (768~8 14) and spent most of his life in the war. It is said that he personally participated in 30 expeditions. He was described as a mythical figure in the ballads handed down by later generations.
Charlemagne's most famous battle was against the Saracens in the southwest. "Saracens" is the European name of Arabs and other oriental peoples. At that time, an Arab entered Spain from North Africa and established the kingdom of Godova. Charlemagne tried to destroy the kingdom, but failed. This battle was later compiled into the famous epic Song of Roland.
According to Song of Roland, after Charlemagne led a great army into Spain, King Cordoba proposed to make peace. Charlemagne's nephew Roland objected. He strongly refuted his colleagues who advocated peace, especially one of them, Ren Lun, as a negotiator. Charlemagne didn't accept Roland's opinion, and still let Guneren be the representative. In this way, Gu Nailun and Roland forged a hatred. Later, in Saracen's court, Gunailun negotiated the terms of peace and conspired with the enemy to assassinate Roland. Charlemagne saw peace and success and returned home with a great army, with Roland as the defender. At this time, King Godova has assembled a powerful army and laid an ambush on both sides of a canyon in the Pyrenees according to the arrangement of Gunellen. This is a very dangerous place. Saracens soldiers and horses are hidden in jungle rocks, commanding enough to kill the enemy.
After Charlemagne's army passed, only Roland's guards marched in the canyon. Suddenly, the Saracens army descended like a tiger and surrounded Roland's army from all directions. In the deafening shouting and killing, Roland repeatedly called on the whole army to fight to the end with the chivalrous spirit of the knight, and repeatedly refused the suggestion that his companion asked him to blow the horn for help and let Charlie return to Li for rescue. In the end, the Franks were outnumbered and wiped out, leaving only Roland and two companions. He just picked up the horn and blew the distress signal. However, blood gushed from the horn and Roland fell in a pool of blood. Charlemagne heard the sound of the horn and was ready to return to Li, but was deliberately obstructed and delayed by Junelon beside him. It was not until Charlemagne heard Roland's last faint bugle before he died that he believed that Roland had indeed been killed, and then he threw off the traitor and rushed back to the canyon. However, Roland and all his companions were killed.
The story of Song of Roland once touched the Europeans in the Middle Ages with its tragic plot, but it actually describes an unsuccessful war between Charlie and Saracens. After that, although Charlie occupied the northeast of Spain, he never moved forward. But after decades of war, Charlie's empire has expanded to France, Switzerland, the Netherlands, Belgium, Austria and most parts of Germany and Italy, and it can be regarded as an unprecedented powerful country in Western Europe at that time. That's why Charlemagne is called "Charlemagne", which means great Charlemagne or Charlemagne.
