The general trend of the world, long-term division will lead to unity, and long-term integration will lead to division. Many famous empires in history eventually collapsed, which is the best proof.

was established in 632 AD. In the early days, a great empire spanning Europe, Asia and Africa was established. After hundreds of years of glory, it finally went to destruction. Why did this happen? Today, let’s look at the various reasons!

1. Special positional relationship
For a considerable period of time, the geographical location of the Arab Empire was not suitable for establishing a strong empire, because establishing a large empire must have the following elements: sufficient productivity, farming land and sufficient water sources, the cultivation of military personnel and combat capabilities, and a large enough terrain can allow its army to have combat space.
However, because Roman and Persian created objective conditions for Arab in the war that lasted thousands of years, allowing it to find enough strategic living space. When Ancient Roman and Persian declined one after another, the Arab Empire appeared with the trend, which was the general trend.

2. Internal disputes continue
Due to the long-term war between the Romans and the Persians, the people of all ethnic groups in the region lived in dire straits for a long time. The founder of the Arab Empire Mumah called out, and the people of all ethnic groups responded one after another and quickly established a powerful empire across Europe, Asia and Africa.
As the saying goes, people in the world "communicate with profit, and if profit is exhausted, they will disperse." The rapid rise of the Arab Empire will inevitably bring about injustice in distribution, which laid the groundwork for the subsequent division.

3. The population is reduced and the labor force is insufficient
Arab Empire is a complex country with multiple ethnic, multi-religious, and multiple beliefs. It is very powerful and it is difficult to achieve true unity in a short period of time. In the past, the people of all ethnic groups were able to unite in order to survive. Once settled down, the conflicts in religious beliefs and the inner dissatisfaction of the lower class people with the aristocracy will cause wars in the country, which will naturally lead to a lack of labor and a decline in population.

4. The failure of external wars
When the Mongolian army came, a country with poor land resources and had experienced hundreds of years of civil and foreign wars, severe national strength loss, national warlords were not united, and leaders had serious defects in its leadership capabilities, how can it fight against Mongolia with extremely strong military capabilities? Therefore, his decline and defeat were inevitable.
