As the subject people of the Norman Empire, the Normans were formed after migrating to France from Northern Europe and merging with the local French, they spoke French, but retained some cultural customs that were different from the French, and naturally William regarded French as the official language of the entire empire.

William's territory, however, was too extensive, with the exception of the French, whose traditional places were French-speaking, and the rest were like Aquitaine in south-western France. Occis is widely spoken in Toulouse and elsewhere, Low German and German are spoken in the Rhine Valley, Norwegian in the Kingdom of Norway, and even in the British Isles, there are several languages, including Old English in England, namely Anglo-Saxon, Scottish Gaelic in Scotland, Irish Gaelic in Ireland, Welsh in Wales, and Norwegian in the Outer Isles of Scotland.

Such a large number of languages caused great inconvenience to William's rule over the Norman Empire, and in many cases, in remote areas other than England, France, and the Rhine Valley, William was unable to form his own government administration, and had to rule by canonizing a large number of noble knights and cooperating with local nobles.

However, is William satisfied with this alone?

No, he would never let this continue, because he knew very well that differences in language and script would greatly increase the centrifugal forces in these regions, and the resulting divisions would be innumerable in the history of mankind. William didn't want his country to fall apart after his death.

Throughout the history of human civilization, the process of establishing a country can be understood as the process of organizing groups of people and societies in different regions according to a certain model, during which the role of language is quite important. Throughout history, most of the powerful empires that have emerged have set up an official dominant language as a channel for the transmission of their decrees, as a guarantee for the smooth flow of their military orders.

The most recent and most famous example is the Austro-Hungarian Empire during World War I, the predecessor of this country, Austria, was a vassal state in the German region, and in the 13th century, the German Holy Roman Empire was divided and chaotic, and the Habsburgs took advantage of this opportunity to actively expand to the periphery with their geographical advantages, and between the 15th and 19th centuries, the power of the Austro-Hungarian Empire increased at an incredible rate, and quickly rose to become one of the major European powers.

By the early years of the 19th century, Austria had become a vast empire, with its territory stretching from western Ukraine in the east, the Alps in the west, the Polish Plain in the north, and the Adriatic Sea in the south.

Because of its mild climate, flat terrain and extremely developed agricultural conditions, the Austro-Hungarian Empire was one of the few large granaries in Europe at that time.

In the later process of industrialization, the Austro-Hungarian Empire followed the pace of the second industrial revolution, and by 1900, the industrial and agricultural strength of the Austro-Hungarian Empire had been among the top in the world, among which the Skoda factory was the largest arsenal in Europe at that time.

However, it was such a powerful country at the time, and after the defeat of the First World War, the country was directly disintegrated by the complexity and diversity of its people and cultures.

At that time, most of the native Germans of the Austro-Hungarian Empire lived in Austria, and the Germans only accounted for about 30% of the total population in terms of population, and did not occupy a dominant position, while the surrounding areas of Austria happened to be multi-ethnic areas, Bohemia and Moravia in the north were the West Slavs who had been highly feudalized, the Kingdom of Hungary in the east was a multi-ethnic and powerful kingdom ruled by the Magyar aristocracy, and the Balkan Peninsula in the south was a typical place with many ethnic groups and complex sects.

However, the Hungarians, Poles, Croats, Romanians, Czechs, Slovaks, Ukrainians and other ethnic groups reached an even position in terms of population and distribution, and surrounded the Austrian-Germans in the center, so that the national question of Austria-Hungary could not be resolved for a long time.

A country without a Juche nation is not conducive to national unity, and later after the rise of European nationalism, this multi-ethnic state was greatly impacted, so that there was continuous internal strife, and the ruling power was insufficient to burst out all the strength of the Austro-Hungarian Empire.

This is also the reason why the Austro-Constitutional army behaved so poorly in the First World War, and so many languages caused great inconvenience to the transmission of government orders and military orders, and it is difficult to imagine how the Austro-Hungarian Empire, with more than 20 languages, could still survive the fierce World War.

Fortunately, the situation on William's side is not particularly serious, as the main ethnic group of the Normans has 1.3 million people, followed by the French with 6 million people, followed by the English with more than 2 million people who use Old English, the Scottish Gaelic language with more than 800,000 people, the Irish Gaelic language with more than 600,000 people, the Welsh language with 500,000 people, the Norwegian language with more than 800,000 people, and in the Rhine valley region, the number of people who speak Low German and German is as high as more than 2.5 million. There are also more than 1.5 million people in south-France who speak Orc.

Thus, more than 7.3 million French-speaking Normans and Francophiles suffered from heat stroke, accounting for 45 percent of the total population.

That is to say, only the more than 7 million people in France can really be used as the cornerstone of the Norman Empire, plus the 2 million people in England that have been ruled by the Normans for a long time, the number of people that William can make full use of only accounts for about 50% of the total population of the empire.

This problem is also relatively obvious in the Holy Roman Empire, at this time the population of the HRE Empire was more than 8 million people, and its main ethnic group was Germans who spoke German, but compared to William's side, the population of the Holy Roman Empire was relatively concentrated, and it would not cause much hindrance from the perspective of population utilization.

Thinking of this, William couldn't help but think deeply, how could he prevent the empire he had worked so hard to build from falling apart?

William came up with two ways to do this, one of which was to use the printing and papermaking techniques he had mastered to print a large number of French versions of the Bible, as well as books on religion, literature, science, and so on, so that everyone could have a French Bible at a cost.

The other way, and the last resort, is to divide the kingdoms with strong centrifugal forces among their sons, so that even if these kingdoms will be separated from the Norman Empire in the future, they can be counted as allies and satellites of the empire, and there will always be a day when they can assimilate.
