The Holy Roman Empire said that William was interested in knowing about the changes through his intelligence channels, but although Bishop Anno II of Cologne kidnapped Henry IV and appointed himself as regent, and the power of the princes under his rule was greatly enhanced, but it was still necessary to let this matter evolve into a fuse that caused civil strife in the HRE Empire, so William was explaining to Russell. Morality. The Count of Bayolle followed up on the matter and put it aside.

At this time, William had other things to deal with, the most important of which were two of them, one was to arrange for someone to compile the "Norman Family History" and the biographies of the ancestors of the past dynasties, including William himself.

Since ancient times, a person's success can be divided into three stages according to the words of Confucianism: meritorious service, virtue and speech, William said that meritorious service is second, no one dares to claim to be first, he developed a small Duchy of Normandy into a huge country that ruled France and England, etc., enough to make him proud.

William has always spared no effort in cultural undertakings and natural sciences, and the Royal Academies in London, Rouen and Paris, the Grand Library and the Opera House in Paris are all the results of his efforts over the years.

At the same time, over the years, William has been restraining the Normans' desire for war, never letting the country fall into endless wars, and generally speaking, the country is peaceful and stable, and gradually prospered and strengthened.

However, in terms of speech, William consciously did not have enough, he did not write Sun Tzu's "The Art of War", Sun Bin's "Sun Bin Art of War", Napoleon's "Napoleonic Code", Mahan's "Treatise on Sea Power" such works that can be passed down through the ages, he also knew that it was not easy to complete this work, so he chose another relatively simple and feasible path, that is, to organize people to compile family histories for the Normandy family, and write biographies of their ancestors.

William hoped that this family history would not only be a book about the glorious history of the Normandy family, but also that it would become the "Chronicles" of the European Middle Ages, and that future generations could understand the magnificent history of hundreds of years ago by reading the family history of the Normandy family.

The "Family History of the Norman Dynasty" is currently published by Enrico Brown, the rector of the Royal Academy of Paris. Morality. Aguileia took the lead, and William only needed to supervise it, so he didn't need to worry too much, but there was another thing that he needed to do himself, and that was to make the coat of arms that belonged to William and the Normandy royal family.

At this time, heraldry was only in the initial stage of development, and it was only a prototype, which was first produced in the army as an identification mark of the army.

It probably arose between the 11th and 12th centuries, and in the famous Bayeux tapestry depicting the Battle of Hastings (1066), it can be seen that the knights of both sides used similar weapons, armor, and shields, the only difference being that the symbols of the shields on both sides were different.

The different emblems drawn on the knights' respective shields were the prototypes of heraldry.

The further development of the coat of arms was not until after the Crusades, and now the coat of arms is still very simple, even William was originally only a double lion coat of arms with a red background, representing his ruler of the Duchy of Normandy.

At this time, another function of the coat of arms was the sign used by the lord to represent himself, so that the subjects could understand who their lord was, after all, almost all people were illiterate at this time, even including most of the knights themselves, in order to better distinguish the attribution, the heraldic system gradually came into being.

When lords choose how to make their coat of arms, they usually choose something to represent themselves, and they also hope that it will give them courage and scare off their enemies.

Generally, lords usually choose two animals, the lion and the eagle, as their emblems, and even William's own coat of arms is a double lion flag with a red background, that is, two golden male lions walking on a red shield.

In addition to the Duke of Normandy, the Duke of Flanders is an erected black lion and the Duke of Aquitaine is a walking golden lion.

The lion comes from Persia, Babylon, and Egypt, and it represents strength and courage, such as Gryffindor in Harry Potter. The lion, a symbol of strength and courage, was so attractive to the nobility of the time who admired martial arts.

In addition to the lion, the animal image of the eagle often appeared in the coat of arms of the nobles at this time, and even in modern times, most empires used the eagle as their coat of arms, such as the Second and Third Reich of Germany, the Russian Empire, the Austro-Hungarian Empire, the Napoleonic Empire and other countries.

The image of the eagle has a strong religious connotation in the coat of arms, Horus of Egypt is a god with a eagle head and a human body, a symbol of royal power, and the pope of Rome is also known as the eagle emperor, St. John is the youngest of the twelve apostles, and he is often accompanied by an eagle, which represents keenness.

The eagle is the natural enemy of the snake, and in Christianity the snake is a symbol of evil, and at the same time, the eagle flies to the sky to represent the process of Christ's ascension to heaven, and in the eyes of Christians, the eagle is the link between heaven and earth that soars through the sky, so the eagle is often used as a symbol of Eastern European empires, such as the Holy Roman Empire, which is later Germany.

In addition to the eagle, there were other symbols used by other nobles, such as the golden castle in the coat of arms of the Kingdom of Castile, and the fleur-de-lis of the Kingdom of France.

Now, William has more than just the Duchy of Normandy, he also has England, Ireland, Scotland, France and Lorraine, and a double lion red coat of arms is no longer enough to represent William, nor is it enough to represent this great kingdom, and he urgently needs a new coat of arms to replace it.

William knew that the three lions were the symbol of the Plantagenet dynasty of England, which represented the three titles of King of England, Duke of Normandy and Duke of Aquitaine, and was also the most impressive symbol of England in later generations.

In the middle of the 12th century, the Norman dynasty was extinct, and Henry, Count of Anjou, France, was crowned King Henry II of England by virtue of the Norman blood of his mother, the princess of England.

Because Henry's wife Eleanor was the ex-wife of the King of France and the duchess of the Duchy of Aquitaine, Henry relied on Eleanor's dowry to obtain the Aquitaine region, because the coat of arms of the Duchy of Aquitaine was also a lion, so after Henry II became the king of England, he ordered a lion to be added to the original double lion flag, and the three lion banners of the Plantagenet dynasty were born.

Therefore, William decided to choose the three lions with a red coat of arms as the symbol of his kingdom of England.

But this was not enough, he also held the crowns of the Kingdom of France and the Kingdom of Lorraine, and the red coat of arms of the Three Lions of England alone was not enough to represent him and his kingdom.
