By the 11th century, the papal immorality had intensified rather than abated.

Benedict IX, also known as Benedict IX, was proplegated to the papal throne at the age of 12 and lived a happy life without shame or shame.

As a pope, he sold his position to his godfather, Gregory VI, for 650 kilograms of gold, who had already recouped the money he had spent by buying and selling his position on a large scale.

At the beginning of 1045, Benedict IX, Gregory VI and Sylvester III, who had abdicated, all claimed to be the pope, known as the "three popes of opposition".

After the three-person tearing began, all kinds of dirty deeds and ugly deeds of the Holy See were exposed to the world, which made people stunned and stunned.

His contemporary, the reformist monk St. Peter Damiani, called him a "sexual traitor", Bishop Benno angrily denounced him as a "criminal, a criminal", and his successor, Pope Victor III, accused him of being "so filthy that I shudder every time I talk about it".

It was the debauchery of the pope and the Church that gave the secular royal power an opportunity to assert its power, and Henry III of the Holy Roman Empire marched into Rome in the early summer of 1045 to convene the Synod of Sutri.

His Majesty Emperor Henry III was ambitious, and he was ready to strengthen his royal power by wresting many powers from the Holy See, including the right to appoint bishops, and to this end he wanted to depose three popes, including Benedict IX, and install a reformist Pope Victor III of Germanic origin.

What the emperor didn't know was that it was his deposed pope that opened the prelude to the struggle between the clergy and the crown, and formed the main line of European history thereafter, the Holy Roman Empire and the Holy See fought for hundreds of years, until both sides were exhausted, and at that time the Holy Roman Empire was in great decline, and lost the opportunity to integrate the princes into a centralized state, and the Holy See also lost its former authority, and Protestantism and Orthodox Christianity appeared one after another but could not do anything.

At the Sutri Church, Henry III wore a rich crown, a white gilt robe, a red cloak on his shoulder, a sword in his left hand, and stepped forward without squinting, followed by the Dukes of Lombardy, Verona and Carinthia, Bavaria, Saxony, Swabia, Bohemia, Brandenburg and many other secular nobles.

Looking at the three unscrupulous popes in front of him, buying and selling the priesthood, and amassing extravagant wealth, Henry III just wanted to say, Brother really can't stand it, don't force me to use my sword!

He knew very well that the Holy See was the ghost that remained in the world after the death of the Roman Empire, and that it absorbed Rome's political structure, governance methods, and laws after the fall of the Western Roman Empire, and also retained many rituals of the imperial court, and that the Holy See managed not only religious affairs internally, but also worldly affairs externally.

In this way, the power of the church in the world came into conflict with that of Henry III, and he and the church were bound to play a game over who had the final say.

From the church's point of view, it is natural not to want a strong royal power, because when the royal power is strong, it will inevitably exclude the church that interferes everywhere. The most advantageous situation for the Church is that all the kingdoms under its jurisdiction are very small, so that the Holy See, which has a sect, can pinch them as much as they want, and pinch them as they want.

In this way, the Holy Roman Empire, the overlord of the European continent, has become a serious thorn in the side of the Holy See.

There are large and small lords in the Holy Roman Empire, from dukes to small counts and barons, and these lords do not want the royal power of the Salian royal family to become strong, because the lords are representatives of local separatist forces, and once the royal power is strong, it will inevitably sweep away the separatist forces and seek greater royal power.

Driven by common interests, the church colluded with the lords and nobles to oppose the royal power and autocracy, and if it faced the separatist forces of the aristocracy and the church at the same time, even Emperor Henry III, who claimed to be the most powerful monarch of the Franconian dynasty, was invincible with two fists and four hands, and the resistance to unity was too great, and he often had the intention to kill thieves but was unable to return to the sky.

However, now that God had given him such a rare opportunity, the three popes in the Holy See were tearing each other apart, holding each other back, and unable to take care of Henry III, and he could take advantage of this opportunity to take advantage of the status of arbiter, depose the pope, and attack the authority of the Holy See.

Pope Gregory VI, for the sake of the free city of Tusculum and Benedict IX's shameful lifestyle, paid Benedict a large sum of money in exchange for his resignation. Regardless of the motive, trading the buying and selling of the priesthood is a violation, and the validity of the legitimacy question of any of them could undermine Henry's coronation as Emperor of the Holy Roman Empire.

So King Henry, with the dual purpose of crowning Holy Roman Emperor and restoring church order, crossed the Alps and marched south to the city of Rome with a large army, accompanied by secular nobles and bishops of the church.

To that end, Henry III cleanly found Gregory VI guilty of buying the priesthood and deposed him, while he also did not recognize Benedict IX and Sylvester III as popes, declared Sylvester imprisoned for posing as pope, and deposed Benedict IX on charges of cruelty, excess, misconduct, and exclusion.

In this way, the three popes were deposed by Henry III, and they put the stage of history, and who will be the new owner of the papal throne depends on the decision of Henry III.

The Saxon bishop of Bamberg, Suydeji of Bamberg, officially proposed by Henry I as the successor of the pope, nominated Suidegi as the new pope and asked the Cardinal Conference and Council to elect him.

This Bishop of Suidge is the Bishop of Bamberg, the Countdom of Bamberg, under the Duchy of Franconia, the direct domain of Henry III, and is a confidant of Henry III.

Soon after, the College of Cardinals and the Council elected Bishop Suidge as the new pope, called Pope Clement II.

There is no doubt that Clement II, relying on the trust of Henry III, seized unimaginable benefits in this battle and became the new pope.

As losers, the three deposed popes Gregory VI, Benedict IX, and Silvet III were expelled by Henry III.

Gregory VI was not willing to accept defeat, and he decided to go south to Apulia to pass to Caesar, Duke of Apulia and Calabria. Morality. Ottwell asked him to send an army against the city of Rome to help him reclaim the throne, even if the city was in flames.
