When Qin Shi Huang unified the six countries, did anything major happen in foreign countries?

In 256 BC, the Roman fleet defeated the Carthaginian fleet south of Sicily and landed east of the city of Carthage in North Africa, plundering more than 20,000 people and sending them back to Rome; In 255 BC, Carthage defeated the Roman army, captured the Roman general Grilla and some of his subordinate troops, and the Roman fleet was sent to rescue the remaining troops. In 249 BCE, the Parthian chieftain Anseses raised an army to overthrow the Greek Seleucid kingdom over Persia and establish the Parthian kingdom. In 246 BC, the famous Carthaginian general Hannibal was born; In 241 BC, Rome annihilated the Carthaginian fleet, seized all of Sicily, and forced Carthage to pay huge reparations; In 238 BC, Rome annexed Sardinia; In 232 BC, Ashoka, the most famous monarch of the Mauryan Empire of India, died; In 222 BC, Rome defeated the Celts who invaded Italy, killed their chieftains, and conquered northern Italy, including Milan; In 219 BC, the Second Punic War broke out, and Hannibal led the Carthaginian army across the Alps into northern Italy; In 218 BC, Hannibal occupied Turin; In 216 BCE, Hannibal won a great victory at the Battle of Connais, and 50,000 elite Roman troops were wiped out; In 211 BC, the Carthaginian army reached the height of Hannibal's glory in Rome, and then began to decline. There is not much information, it is not comprehensive enough, please bear with me.

In the 3rd century BC, there was a conflict between Rome and Carthage. In 264 BC, the First Punic War between Rome and Carthage broke out, with the focus entirely on Sicily. In 241 BC, the Carthaginians and the Romans signed a treaty in which they had to abandon Sicily and pay war reparations.

After the loss of Corsica in 238 BC, the Carthaginians began to strengthen their rule in Europe. By 218 BC, they had built a powerful empire in Spain, increasing in wealth and power.

Defending the country, the country's real Kuan Zhi Tong power is relatively weak, they eventually became vassals of the princes Shentan, and in the later period, they became vassals of the Qin State, and Qin Shi Huang was very good to this country.

That country is a patriotic country, and its military and economic capabilities are very weak, and Qin Shi Huang did not bother to attack countries weaker than him, so he let the country go.

This country is Zheng Guo. After all, this country is a vassal state of Qin, and it is impossible for Qin to destroy this country for the sake of face.

In 221 BC, when Qin Shi Huang unified the world, many other things happened at the same time, including:1End of the Zhou Dynasty:

By this time, the Zhou dynasty had declined, and the Seven Kingdoms were constantly fighting each other, and were eventually destroyed by the Qin Dynasty. 2.The Rise of Confucianism:

Confucianism began to emerge during the Spring and Autumn period, but it was only after the Qin Dynasty that it really spread widely. The ideas of Confucius are considered to be at the heart of Confucian morality and culture. 3.

6.Construction of the mausoleum: Qin Shi Huang ordered the construction of his own mausoleum, which is also where the later terracotta warriors and horses were unearthed.
