The Persian Empire is a monarchical empire centered on Persians. It first began with the Achemani Dynasty established in cyrus the great in the 6th century BC. Thanks to the efforts of Persian kings in past dynasties, the imperial territory reached its peak from the Indus Plain in the east, Egypt in the south, the Balkans in the west and the Caucasus Mountains in the north, with a territory area of about 7 million square kilometers. It is the first empire in the world that spans Europe, Asia and Africa. In ancient times, no country could rival the Persian Empire, but such a powerful empire eventually disintegrated in internal differentiation and was overthrown by Alexander the Great from the north.
Roman Empire, an empire spanning Europe, Asia and Africa, controlled about 5 million square kilometers of land in its heyday, and the Mediterranean Sea became an imperial inland sea with a population of about 65 million. After Theodosius I split the empire in 395 AD, the Eastern Roman Empire was fortunate to be the oldest monarchy in European history, which lasted for a thousand years.
The Arab Empire is an Islamic empire established by Arabs in the Middle Ages, which is often called "big food" in China history books. After 626 years, the Arab Empire reached 654.38+03.4 million square kilometers in its heyday. It is called' the longest empire in the ancient history of the world' and the fifth largest empire spanning three continents. The Arab Empire was so powerful that there were many conflicts with the Eastern Tang Empire during its development. In 75 1 year, in central Asia, he fought Tang Jun in China, and 20,000 Tang Jun did not lose ground against the Arab army with a total of150,000. However, due to the disparity in strength between the two sides and the rout of local forces, Tang Jun suffered a fiasco. However, due to the painstaking efforts of the Anxi government in the Tang Dynasty for many years, the Japanese pirates also suffered greatly. But such a powerful empire was trampled out by the powerful Mongolian empire at the end of 12.
As one of the most powerful countries in the world at that time, especially during the reign of Emperor Xuanzong of the Tang Dynasty, the Tang Dynasty made great efforts to govern and created a prosperous move for all ethnic groups to come to the DPRK. The territory of the Tang Dynasty was unprecedented, with a population of about 70 million in its heyday and a territory of120,000 square kilometers. It is also the first unified dynasty since the Qin Dynasty that did not build the Great Wall. The fame of the Tang Dynasty was so great that overseas Chinese claimed to be Tang people.
The Mongol Empire is the collective name of the Yuan Dynasty and the Four Great Khan Countries founded by Mongols. Its founder Genghis Khan is the most outstanding political strategist in the history of the world. During his lifetime, he invaded the west and extended the territory of the empire from the Caspian Sea to Beijing. After his death, later generations inherited his legacy and threw God's whip into Europe, which made Europeans covet Mongolian soldiers from the East for hundreds of years. In this way, through the efforts of three generations, the Mongols established an empire across Europe and Asia, with a land area of 3,300 square kilometers at its peak. The Mongolian Empire deserves to be the strongest and largest super empire in the history of the ancient world.
