The division method of Napolica IV, the "barbarian slaughterer", is to call the history before the founding of the Sulasi as prehistory, after the founding of the state to the civil war between the north and the south as ancient history, after the end of the civil war until the eastward expansion stops as modern history, and before the eastward expansion ceases until the Sushi rebellion stops, it is called modern history, and then it is called contemporary history.

Prehistory has two epochs, both newly coined by Napolica IV, the Dark Ages and the Barbaric Ages, and the dividing point is still Doleiman as the leader.

Ancient history is divided into two eras, the Archaic Age and the Classical Era, both of which were also coined by Napolica IV, and the two eras are divided by the death of Moxi.

The following era of modern history is the era of modern history, and the previous eras named after the chief priests were all abolished and replaced with the era of eastward expansion, in other words, the era of eastward expansion is modern history.

In modern history, the method by which Polika IV inherited the previous title, i.e., named the era after the chief priests, I guess it may have been because those men were so close to the present that their children and grandchildren were still alive?

Contemporary history, on the other hand, is not innovative, and still follows Moxie's words, the present era.

Napolika made some changes to the way in which contemporary and modern history was treated. Contemporary history is only the present era, and all the eras named after people are classified as modern history.

In addition, the main contribution of the Napolica IV division method lies in three points:

First, Napolica IV first introduced the concept of the "era of eastward expansion" into the history of Sulassie, and the era of eastward expansion as Sulassie later called it can be traced back to Napolica IV becoming the official national title.

Second, the prototype of the concept of the ambiguous transition stage began with the division of Napolica IV, although Napolika IV himself was not aware of this, but the so-called ambiguous transition stage in later historiography can be traced back to this division of Napolica IV.

Thirdly, the beautiful words of the Dark Age, the Barbaric Age, the Archaic Age, and the Classical Age have influenced later generations, and although their meanings have changed many times in the course of circulation, they have at least survived.

First of all, the statement is called the "Age of Eastward Expansion", and Napolica IV creatively elevated the Eastward Expansion Era to a concept, referring to the era of the Surassians who wantonly expanded and colonized the East.

In Napolika IV's division criteria, the era of eastward expansion officially began in 231, in this year, the ancestors of the Suhi finally lost their nest and fled eastward in disarray, and Napolika established a city named after itself on the ruins of the former residence of the Suhi, which is today's Napolika, which was the capital of the Sulasi people for a long time.

Napolica IV believed that the establishment of the city of Napolica marked the expansion of the Sulasi to the east, doubling Sulasi's territory within a few hundred years.

The era of eastward expansion ended in 703, because from this year onwards, the pace of eastward expansion of the Surassians slowed down to the point of a halt.

As a reminder to readers, the end of the era of eastward expansion was claimed by Napolica IV, and non-modern scholars believe it. Because that era is so far away from us, there is really no strong data to support the highly subjective judgment of when the eastward expansion will stop, and the historians of Surassi are still debating this issue endlessly.

Since I am not here today to discuss the question of the eastward expansion of Sulassi, I will not delve into this issue in further detail, but the reader only needs to understand that it is sufficient for Napolika IV to claim that the eastward expansion of Sullahsi ceased in 703.

The second point, the stage of fuzzy excess, is also an important concept, and I must remind readers that the concept of fuzzy excesses proposed by Polica IV is not exactly the same thing as what we now call the concept of fuzzy excess.

When Napolika IV divided, he thought that there was no need to make an extremely clear judgment on the dividing line of the era, because although the era is changing, it would be very boring to insist on finding a node in each era.

For example, the era of the Civil War between the North and the South can naturally be divided according to the year in which the war broke out, because the time that followed swept the whole of Surasi. But in other times of peace, it is nonsense to divide by years, but in order to distinguish between times, it must be divided.

Therefore, at this time, it is up to whoever finds a landmark event, mostly the alternation of the chief priests, and then specifies the time of the division. What if there are extra years in between the two eras?

Readers may be confused by this, so I'll actually give you an example.

In Napolika IV's division method, the end of ancient history was marked by the civil war between the north and the south, that is to say, in the year 202 of the Great Calendar, but Napolica IV divided the beginning of the modern era to 231 years, so that 29 years were lost in between, and they belonged neither to antiquity nor to modern times.

This question was asked back then, and Napolika IV put forward the above concept, which is too vague, and blurs this period of history, and does not delve into which era it belongs to, you can see it as the previous era, or you can see it as the next era.

Anyway, that era is so far away from now, and blurring won't affect anyone.

In today's historiography, the concept of excessive ambiguity refers to the blurring of the intersection of two eras, and when someone mentions this period of history, it can be classified as either the previous era or the next era.

The biggest difference between the concept of excessive ambiguity and Napolica IV in the current historiography is that Napolika IV very clearly limited the excessive ambiguity to the time period vacated by the two eras, while the current historiography does not have this rigid requirement, and can be directly placed in the era, as long as you can find the connection point between the two eras when you discuss the article.

(4) Suxi's early dynasties

When Suxi first founded the country, although he always maintained an offensive against Sulasi, he was full of inferiority complex in culture, and many places were directly moved from Sulasi, and the history of the dynasty was included in it. At first, it was the Napolika I dynasty, and later the Napolika IV dynasty.

It was not until 794 A.D. that the first chief priest who did not participate in the war of the founding of the Su-Xi state, Kierg I, became the fourth chief priest of Sushi, and decided to make efforts to get rid of the cultural inferiority of the Su-Greek people.

With the efforts of Kierga I, Sushi introduced his own dating method, known as the Kierga dating method, which replaced the original Napolika IV dating method.

But unfortunately, in Kierge's view, there are many things to be done to get rid of the cultural inferiority of the Sussi, among which the aspect of the dynastic method is obviously not an important thing.

Therefore, the so-called Kierge dating method, the way of dating is extremely simple, for prehistory, ancient history, modern history and contemporary history, Kierg completely copied the Napolika IV dating method, and even the name of the era is the same, only the era of those names in modern history was changed by Kirger, but the template is still Sulassi.

Therefore, in addition to increasing the self-confidence of the Sushi people, the Kierge dating method actually has little value, and it is a very rubbish dating method.

The first set of valuable dating methods of Sushi was the Lesono dating method introduced by the 10th chief priest Lesono I in 848, which was the first set of Sushi's own dating method.

In Lesono's dating law, he divides history as follows.

Prehistory: Governing the primitive era and the obscurantist era, the dividing line is still the "ancestor of magic" Moxi became the leader of the Doleiman tribe.

Ancient History: Ancient, Medieval and Early Antiquity, with the two dividing points being the conquest of Napolica by the Surasi and the emergence of the Beastmaster system.

Modern History: The era of the founding of the state and the era of the Western Expedition began with the outbreak of the rebellion of the Suhi people, with the occupation of the chief priest of Seleuriad as the dividing line, and ended with the signing of the Treaty of Seleuriad.

Modern History: The era is still named after the boundaries of the three chief priests.

Contemporary History: Subordinate to the present era.

The Sussi's greatest contribution to this Lesono dating method is twofold:

The first is the concept of establishing the method of dynasticism because it is based on the history of the main ethnic group, which later influenced the dynastic of Goshoge.

The second is to change the barbarism and darkness that Napolica IV spoke of to be primitive and obscurantist, and in fact we still use these two words to refer to the past era, which is the contribution of Lesono I.

(5) The development and simplification of the dynastic history of the two countries before the founding of the People's Republic of China

The founding of Sushi was a drastic change, marking that the Sulasi cultural circle was no longer the only player in Sulasi, so the dynastic law was also renovated during that time.

Since then, however, there has been little welcome development in the two countries in terms of dynastic history, reverting to the old path of the previous 500 years before Sulasi, and the other eras have remained largely unchanged, and the years of modern history have been getting longer and longer.

However, when I say generally unchanged, I only mean that the official documents have remained largely unchanged, and in fact the biggest change in the past two hundred years has come from the people, and that is the famous trend of simplification.

The simplification trend first started in Xingqimu and then quickly spread to Sulasi and Sushi, and the theory of this trend is probably as follows: history does not need to be so complicated, there is no need to divide it one era at a time, and all those complex concepts should be simplified.

To give a simplification scheme, a student in Shipali believes that history should only need four stages, the prehistory before the founding of the Sulasi, the ancient history before the founding of the Sulasi, the modern history before the founding of the Sussi state, and the contemporary history of 30 years of the same period, which is the division of history.

And there are many people who have this idea, and they have come up with hundreds of schemes, and to this day we can still see fifty-six schemes in Nishiel's "Miscellaneous Records".

Unfortunately, the proponents of this trend were fighting on their own and their own internal struggles were still fierce, so they did not receive official attention, and as the war between Sulasi and Sushi heated up, scholars gradually became attracted to the Restoration, and the first popularity of the simplification trend quietly dissipated.
