How did the Persian Empire rise to become a great power in history?

The ancient Persians were a small tribe living on the Iranian plateau, mainly immigrants. Until the beginning of the 6th century, they were a small tribe that nobody cared about. Of course, the rise of the Persian Empire was a very long process. Before that, they were a savage tribe. In the process of plundering other tribes by brute force, they also absorbed the cultures of other tribes, but it also easily led to the disappearance of their original culture and cultural instability, but even in this case, the Persian Empire still existed as the largest and strongest country in history, although it did not occupy the mainstream position.

In the era of Ju Lushi, the Persian Empire began to rise rapidly and began his expedition. First of all, it combined other tribes in the Iranian plain with some foreign tribes and destroyed the kingdom of Mittai. The kingdom of Mittai is not a small country. It was formed after the demise of the famous Assyrian Empire. So at that time, many Persian tribes actually belonged to the kingdom of Mithai. Therefore, after Ju Lushi destroyed the kingdom of Mittai, Ju Lushi actually ruled all the tribes under Mittai's rule. In this case, Ju Lushi is not only the leader of a small tribe, but also the king of a great kingdom, which is also a very big turning point of the Persian Empire, which also means that this is the beginning of the prosperity of the Persian Empire.

He didn't destroy temples or kill cities, so many enemy countries even opened their doors and voluntarily accepted Ju Lushi's rule. For many people who have suffered from war for a long time, he is the savior of Mediterranean civilization. Cyrus the great catered to the people's desire and voice for peace in the Mediterranean civilization circle. He wants to use war to destroy all wars and bring permanent order and peace. The Persian Empire was the first time that Indo-Europeans stood at the top of Mediterranean civilization.

The most valuable thing is the infrastructure of the Persian Empire. Darius started the imperial post system. If you want to build roads before you get rich, the economic and trade level of the Persian Empire has risen by an order of magnitude because of convenient transportation. Under the rule of Darius, the Persian Empire was reborn and its territory was unprecedented. An empire spanning Asia, Europe and Africa was formally established. Darius thinks he has made great achievements. He recorded his achievements on the cliff and described his great achievements in life. This is the famous inscription of Bethesda in later generations.
