The Carolingian dynasty originated as a tribe of the Franks, a Germanic peoples in present-day central France, and in the midst of chaos and turmoil, it was highly likely that they could rise to prominence.

It was under such circumstances that Pepin, who was able to do so and had the support of the army, overthrew the old king of the tribe and appointed himself the new king.

At this time, there was a foreign invasion on the border of the Roman Empire, that is, the Lombards, and the pope of the Roman Church came up with an idea of mutual benefit: that is, to ask Pepin to send troops to attack the Lombards together with the army of the Roman Empire, and if he won the battle, the Pope of Rome would publicly coronate King Pepin and make him king.

Unexpectedly, Pepin won the battle and gave part of the occupied Lombard territory to the Pope as a great gift, and its function was to make its Roman city have a safe and buffer protection around it, so that the enemy could not easily invade, which is the historical 'Pepin sacrifice'.

Therefore, some local kings in Europe began a new understanding because of Pepin's example: as long as the king can be crowned by the Roman pope, even if he was the king himself, it will have legitimacy at this time, and at the same time, the people can be convinced and have substantial authority to command the people and territories to which they belong.

This is the origin of the coronation of European monarchs, especially for a self-proclaimed monarch like William, who urgently needed to hold a coronation ceremony for him through the Pope of Rome, so as to give legitimacy to his throne, to be recognized by the princes of various countries, and to convince the nobles and the common people.

In addition to the crown, the objects used in William's coronation were a scepter, an orb, and a sword.

Scepters are divided into knots and baguettes. The scepter is a symbol of the royal power's orders and a reminder of the importance of justice to the ruler, who must be granted this item in order to obtain the crown from above. In the Middle Ages, the scepter and the crown became the two main symbols of the royal family.

The consecration of Charles the Bold in Orleans, King of West Francia, in 848 AD is the first recorded appearance of the scepter as a coronation ornament. In 876, shortly after his coronation as emperor, Charles used a scepter and a long stick as symbols.

The power stick or power stick is believed to be derived from the shepherd's stick or handle, symbolizing the pastoral aspect of the king's rule. It was first used by the ancient Egyptians and the peoples of the Near East as a symbol of royal power. The Romans were a late adopter, and the baguette represented the magistrate's office.

The battle and the baguette were so cumbersome that at William's suggestion, Bishop Hamelin combined the baguette and the baguette into one, called the scepter, which was made of gold, complete with precious stones and pearls, and topped with a cross.

The orb, an ancient imperial symbol, signifies the Roman domination throughout the world and represents the authority of Christ (the cross) over the whole world (the orb). In the 4th century, Emperor Theodosius I added a cross, thus giving the orb Christian significance.

In the West, the orb began as a purely iconographic symbol in the 11th century, when it was offered by Pope Benedict VIII to the coronation of Emperor Henry II of Saxony (1014). However, it was not until the coronation of Henry VI that there was tangible evidence that the orb was indeed used for the coronation of the emperor. It is said that Henry's acceptance of symbols from the pope was highly questionable, because the acceptance of the orb showed that the emperor's secular power came from the church and not directly from God.

In England, it was not until centuries after it was introduced as an iconographic symbol that the orb was used as an actual symbol of kingship.

The first seal of Edward the Confessor uses the orb motif, making it a royal symbol, depicting Edward the Confessor holding an orb without a cross in his left hand. Harold follows in Edward's footsteps: a Bayeux tapestry shows him sitting majestically, holding a treasure ball with a cross in his hand. William the Conqueror is shown holding a scepter orb, a orb designed for use by the English monarch (the distinctive feature of the scepter orb is that the cross is inserted into the orb's rod rather than directly into the orb).

The sword, which symbolized the authority of the monarch and its leading role in war, was introduced into the coronation ceremony and may be an illustration of the Christianization of pagan practices in the early church. The Church's participation in the conferment ceremony was at the coronation of the Carolingian Emperor Lothar in 823, when Lothar wore a sword conferred by the Pope.

The sword at the coronation ceremony had two symbolic functions, defending the church and protecting the people, and the awarding of the sword symbolized the surrender of the kingdom to the king for governance.

The sword is considered one of the most effective symbols of royal power, as important as the crown and the scepter, and holding or holding the king's sword is a way for important people to acknowledge their dependency and subordination.

The coronation ceremony was roughly scheduled for June 2, 1042, and before that, William had to send invitations to the monarchs and invite them to come and watch the ceremony.

William's father-in-law, Emperor Ferdinand I of Spain and King of Castile, was an important invite, as was Edward, the newly crowned King of England, and King Henry I of France.

Although William and Henry I did not have a good relationship, and even had a deep hatred, His Majesty the Pope was coming, and as a monarch of a country, Henry I had to come to William's coronation, no matter how much he hated William.

These lists of those who were invited to the ceremony were the result of careful consideration by William and the nobles, including the princes of France, the nobles of England, the kings and dukes of Spain, and the princes of Italy, all of whom were close to William or had various entanglements.

William did not invite the nobles of the Holy Roman Empire to his coronation, because he felt that he was not close to the German princes, and that they were far from each other, so they did not intend to invite each other.

However, Count Adolf later dissuaded William, hoping that William would be treated equally, and invited the emperors and princes of the Holy Roman Empire to attend the ceremony.

However, in the end, William could not confirm whether these princes, nobles and monarchs invited by William would come in person, send envoys to watch the ceremony, or even refuse directly.
