Ancient Eastern civilization is very mysterious, and the characteristics of Western civilization are more diverse, both sides are in a state of happiness and harmony for a long time, but suddenly they all began to fight, Eastern and Western civilizations began to start wars invariably, because before the first millennium BC, the global temperature was relatively warmer and more stable, and after the first millennium BC began to decline sharply, ushering in the first low temperature period since human history records, Such temperature changes have caused people in various parts of the world to begin to migrate to a certain extent and compete for resources, friction with each other has led to various wars, and the alternation between Shang and Zhou is almost at this time period.

In the first thousand years of B.C., Eastern and Western civilizations began to wage wars invariably, and each big country also spared no effort to sweep away the surrounding small countries, but the final result was often that these big countries were magically sending experience to small countries, sending heads to small countries, sending prestige to small countries, and then being overthrown by small countries.
First, hesitation will be defeated, and decisiveness will be given in vain
In 492 BC, the largest Persian Empire in the West and the most democratic Greek city-state, Athens, went to Athens with two hundred ships, leading an army larger than the total population of Athens, and the Persian army embarked on a journey with great enthusiasm, vowing to set foot on Athens. However, a gust of wind blew the Persian fleet into the sea from nowhere, and the powerful Persian army was inexplicably taken by Athens.
Then the second time Persia took six hundred ships to attack Athens, the two sides began to line up on the plain of Marathon, the Persian side of the cavalry, infantry, archers totaled tens of thousands, while the Athenian side only infantry, and the strength of the troops was only more than ten thousand, but it was in this extremely unfavorable situation for Athens, Athens launched a charge to Persia, the result can be imagined - Athens won again.
After Persia returned, it was painful and deeply reflected, and finally thought that the reason for its failure was definitely that people had not yet brought enough, so when the third Persian expedition to Athens, Greece, led hundreds of thousands of troops composed of fifty-eight nationalities to Greece in a mighty way, but our mighty Persian Empire still lost by accident, expectations, unexpected, and tireless efforts: first it was blocked in the hot springs by only three hundred Spartan warriors and thousands of remnants for several days, and after passing the Spartan pass, The Persian ship at sea was smashed by Athens, and the Persian Empire, which was called "invincible", lost again.
Second, the Wu-Yue dispute in the East
At the same time, the East and the West in this period are different, the weak victory over the strong on the eastern battlefield does not look as white as the Western Persian Empire, in 494 BC, the Yue King Gou Jian raised the army of the country to preemptively pounce on the Wu State, which was ten times stronger than himself, ready to take advantage of the opportunity to take the Wu State before the Wu State was discovered, however, the Yue King Gou Jian soon lost.
However, the history of both the East and the West will tell us a truth, sometimes the dying struggle can indeed be exchanged for a way of life, but unfortunately, often most people will choose to prematurely give up that glimmer of vitality and dying struggle, the Wu army directly pressed back to the Yue kingdom, the Yue king Gou Jian inserted wings and could not fly, at this time Gou Jian also intended to be a righteous soldier who was not afraid of death, but chose to surrender with humble words, the lowest stature and the most abundant financial report, and was willing to "taste the dung" for the King of Wu. In the end, the feat of being humiliated by Wu Palace for three years to being paid for ten years to swallow Wu was achieved.
After that, the Spring and Autumn period was also nearing its end, and after the three families of Zhao Wei and Han were divided into Jin, the Spring and Autumn Five Hegemony era gradually became the era of the Seven Heroes of the Warring States.
Iii. The beginning of the dynasty
From Confucius to Guan Zhong, from theory to practice, even in the era of a hundred schools of thought, the various schools were far from being able to reverse the chaotic situation in the Spring and Autumn Period, and after the Warring States, the ideas of "benevolence, courtesy, and filial piety" advocated by Confucianism, the "inaction" advocated by the Taoists, and the "legal system" pursued by the Legalists were all retained from the Spring and Autumn Period to the Warring States, and also slowly penetrated into the vast land of China, of which the "legal system" pursued by the Legalists was particularly outstanding, and the Ideas of the Legalists laid the foundation for the great cause of the subsequent unification of China by the Qin State.
At this time, Athens is completely a scene of "gongs and drums, firecrackers in unison, red flags, and a sea of people", because Athens, which won the war against Persia, can boast with these three proud achievements, and Athens has indeed become the ally of The Greek cities by naval superiority, and Athens' own dream is the sea of stars, but Athens' dream is really the sea - Athens established the first greek port, Piraeus, becoming the most lively city in the world at that time. A large number of people poured into the city in pursuit of power, wealth and power, and many people rushed to Athens, which entered the golden age and became one of the most powerful city-states in Greece.
At this time, Sparta was very upset and decided to go to Athens, after two Peloponnesian Wars, Athens was defeated, and it was precisely because of this infighting in Greece that Macedonia in the north took advantage of the situation and engaged in a wave of things. After the death of the old king of Macedonia, Alexander the Great ascended to the throne, and after ascending the throne, he wiped out Persia, and then Alexander may have died of malaria because of the real "pressure on the mountain", and Rome followed on the stage of history.
At this time in the east, the Qin king Yingzheng had almost finished cleaning up the other six countries, and Yinzheng became the first emperor, that is, the first emperor of China's feudal dynasty. In India at this time, Buddhism and Hinduism were prevalent, and there was a brief rise of the Peacock Dynasty in between.
At the same time, the two seemingly completely separated worlds of the East and the West were suddenly connected by a road that appeared later, and various cultures began to communicate, and after the history of world wars in the first millennium BC, the history of cultural aggression slowly began.
IV. Conclusion
In the world melee in the first millennium BC, the cultures on both sides of the east and west gradually appeared more stable, and in the world melee in the first millennium BC, the battle of the weak to win the strong became gradually becoming common, some people think that the military thinking at that time was not high, resulting in the low efficiency of the command of the army with a large number of people, and some people believe that the victory of the big country will not cause too much attention, and the battle won by the weak will be so famous.
The course of human history is complex and magical, and in the history after the Common Era, there must be more magical and interesting history waiting for people to interpret.
