The first dynasty that claimed to have unified the whole Indian subcontinent was the Majestic Empire established by the Peacock Dynasty (from 322 BC to 185 BC, in fact, the subcontinent was not completely unified, and there were still many small kingdoms in the south that were not within the territory of the empire).

By the time of Ashoka, the grandson of Chandragupta, the peacock dynasty reached its peak. Eight years after he ascended the throne, he conquered the country of Jielingjia on the southeast coast. At this time, the territory of the empire almost included a considerable part of India and Afghanistan except Tamil areas.

With its unprecedented national power, the Peacock Dynasty accomplished many important undertakings. For example, Chandragupta has built a developed road system all over India. There is a post station on the road, and a post is built every half mile for marking. In the Ashoka era, trees were planted on both sides of various roads, and a well was dug every three miles to set up a place for pedestrians to rest. Near the intersection of main roads, national granaries and warehouses are set up for emergency use. In addition, in order to increase agricultural output, the empire also built canals and reservoirs in various places and established a relatively complete irrigation system. In order to carry out his political ideals to the people, he erected many stone pillars and carved imperial edicts in various places under his jurisdiction to show his determination and hope to win the support of the people. These imperial edicts are written in many languages and are called "Imperial edicts of Ashoka".

After the death of King Ashoka in 232 BC, the Mojietuo Empire was split, and some areas were occupied by the "Daxia Kingdom" from the north-the situation in northwest India and north India changed again in the second half of the 1th century A.D.-a great empire appeared-it was with the Roman Empire, the Rest Empire (now Persia, Iran) and the Han Empire (needless to say this? ) and known as the "heroic age" of the four empires-Guishuang Empire!

Guishuang people were originally a nomadic people living in the western part of the Mongolian Plateau, and they were called "Dayue's family" in China's ancient books (remember that Emperor Wu of the Han Dynasty sent Zhang Qian to the western regions to contact Dayue's family to attack the Huns? ), since they were defeated by the Wusun people (around 176 BC), they began to move south to the territory of Daxia (now Afghanistan), and then marched south and east after conquering Daxia.

After the founding of Kujula Kadphises, the country became stronger and stronger, and it invaded India, destroying the remnants of Daxia country in India. Later, during the reign of Yan Gaozhen and Ganeshega, it continued to invade India, and all the places from the west of India to the middle of the Ganges River basin were included in the territory of Guishuang Empire, and even the capital of Dayue was moved from Central Asia to Fulousha (now).
