Yu is the leader of the Xia tribe alliance in the Central Plains. After he became the "co-owner" of the tribal alliance, he tried to form an army, levy three seedlings in the south, build a city and formulate a criminal law, which laid the foundation for the establishment of the first dynasty in China history-Xia.

After the founding of the People's Republic of China, Yi (Boyi) was elected as the heir to the throne. After Yu's death, according to the tradition of tribal leaders' alliance, Yi held a funeral for Yu and mourned for three years. After three years of funeral, Yi failed to inherit the throne.

"Yi Yu, the shallow, not contacts. So the princes went to benefit and began to move forward. " "Mourning for three years, the son of the emperor began to help and took refuge in the grandson of Jishan" (historical records. Xia Benji "); Therefore, the history of China has entered the slave society of "home is the world" from "the world is the world for all".

Since then, abdication system has been replaced by hereditary system. This indicates that the long primitive society has been replaced by private ownership society, which should be said to be a progress in history. However, the establishment of a new system will inevitably encounter some objections.

Later, many tribes inclined to abandon tradition questioned Kay's power. On the outskirts of Qidu, the Hu family fought bravely and led a tribal alliance to crusade against Qidu and fight against Gansu.

Before the war, he claimed that his power was "respecting heaven", which was the embryonic form of the theory of the son of heaven in the Zhou Dynasty. Qi has been recognized by the people of the Central Plains and has a great advantage in numbers. Finally, he defeated the Youhu family and was punished as a herdsman. This victory represents that the mainstream social concept in the Central Plains has changed from the original abdication system to the hereditary system.

Extended data:

First, the historical record of the first slavery dynasty:

Xia dynasty (about 2070- 1600 BC) was the first hereditary dynasty recorded in China's history books. There are a certain number of bronze and jade ritual vessels in the cultural relics of the Xia Dynasty, dating from the late Neolithic Age to the early Bronze Age.

According to historical records, Biography of Yu was written, which changed the abdication system of primitive tribes and initiated the hereditary system in China for nearly 4,000 years. Therefore, the "home world" in China's history began with the establishment of the Xia Dynasty.

1 1 tribes of Xia nationality are related to the central royal family in Xia Houshi by blood, political enfeoffment and economic tribute, which roughly constitute the core territory of Xia dynasty. Summer begins in the west of Henan Province and the south of Shanxi Province, east to the junction of Henan Province, Shandong Province and Hebei Province, south to the north of Hubei Province and north to the south of Hebei Province. The geographical centers of this area are Yanshi, Dengfeng, Xinmi and Yuzhou in Henan Province.

It is generally believed that the Xia Dynasty lasted for fourteen generations, and after seventeen generations (the ruler of the Xia Dynasty was called "Hou" when he was in office and "Emperor" after his death), it lasted for about 47 1 year and was destroyed by the Shang Dynasty. Later generations often call themselves "Huaxia", making it synonymous with China.

Second, the battle for power: the battle of Gansu

Legend has it that in the Yao and Shun era, tribal leaders, that is, rulers, needed everyone to discuss. For example, Yao, Shun and Yu were all elected leaders because of their high ability.

However, with the gradual accumulation of wealth, society is divided. When they have greater strength, some people are no longer willing to abide by the previous rules. After Dayu's death, he became a tribal leader, but Yu's son wanted to seize power, and he was already very powerful. So, Kay and his supporters joined forces to fight against Yi, eventually killing Yi and gaining the position of leader.

However, the status of the leader of Qi was not proper, which caused dissatisfaction among many other tribes, especially the powerful Youhu family, who openly opposed Qi. In order to establish their own position, Qi launched a war against the Youhu family, which is the famous "Battle of Gan".

At that time, Hu had a great influence. In order to defeat him more smoothly, Kay made some mobilization before going out to war.

This mobilization of the Gansu campaign has become a model for future wars. First of all, you should find a reasonable reason to go to war, for example, you are doing justice for heaven; Secondly, we must strictly abide by military discipline and urge all soldiers to do their duty; Finally, rewards and punishments should be clear, and everyone should be encouraged to work hard with generous rewards.

The victory of the battle of Kaiguang Gan means that Wang and his "six people" completely replaced the Tang envoys, and the hereditary system of kingship was established. After the war in Gansu, the first dynasty in the history of China was born, and China entered the historical process of slave society.
