Qin Bigong
In 501 BC, Duke Bi of Qin died, his son Duke Yi of Qin died early, and his grandson succeeded him as Duke Hui of Qin.
Qin Huigong I, reigned for ten years, during the reign, the Qin state continued to decline, lackluster, there were some major events in the world, Jin Guozhi, Zhao, Wei, Han Sishi, the annihilation of the Fan clan, the Zhongxing clan, at the same time, Confucius rose in the Lu state.
In 491 BC, Duke Qin mourned the succession, reigned for fifteen years, during the reign, the only major thing done was to build a city wall in the capital city of Yongyi, Yongyi, that is, in the area of Fengxiang County, baoji City, Shaanxi Province, during the Spring and Autumn Period, the Guanzhong River crisscrossed, Yongyi as the capital of Qin for three hundred years, surrounded by large rivers, therefore, known as the water capital of Qin, has not built a city wall, because there is a natural moat guard, but during the Period of Qin Mourning, the country's strength is declining day by day, and the sense of crisis is getting heavier, so the city wall is built.
In 476 BC, Duke Mo of Qin died, and his son succeeded to the throne for Duke Li of Qin, who reigned for thirty-four years, during his reign, some of them made achievements, sent troops to attack the state of Dali Rong in the east of Guanzhong, destroyed it, and seized its capital city of Dali Wangcheng, which was the capital of the Western Zhou Spring and Autumn Period and the capital of the King of Zhou, so it was called Wangcheng, which was now attributed to the Qin State. Qin Ligong not only marched east, but also led troops to the west, attacking MianzhuRong in Longxi, forcing him to submit to his subjects. Not only that, but he also carried out a northern expedition, defeating Yiqu Rong north of Guanzhong and capturing his king.
However, there were also many losses, and the Jin state sent troops to defeat the Qin state and capture wucheng in eastern Guanzhong, around hua county in present-day Weinan City, Shaanxi Province.
After Duke Li of Qin, his sons Duke Of Qin and Duke Huai of Qin succeeded to the throne successively, at that time, the State of Qin was in decline, the old nobles controlled the power, state affairs were chaotic, and in 425 BC, the nobles of the State of Qin forced Qin Huaigong to commit suicide.
After that, the throne of the Earl of Qin formed two lineages, and the Duke of Qin Huai had two sons: Qin Zhaozi and Qin Jiangong. At the time of his death, the eldest son, Qin Zhaozi, had already died prematurely, and the nobles made Qin Zhaozi's son Qin Bo the Duke of Qin Ling, because of his young age, he was easy to control.
Qin Zhaozi is a line of heirlooms.
Qin Linggong reigned for ten years, at this time, the powerful Jin state collapsed, Zhao Wei and Han three kingdoms were established, Qin Linggong thought that there was an opportunity to take advantage of it, so he moved the capital to the east, leaving the three-hundred-year capital of Yongyi in the central and western part of Guanzhong and moving to Jingyang in central Guanzhong.
Duke Ling of Qin died in 415 BC, and his son Gongzi Lian, young, was seized the throne by duke Linggong of Qin, and the title was transferred to the line of Duke Jian of Qin.
During the reign of Duke Jian of Qin, there were certain reforms, he allowed officials and ordinary people to carry swords, breaking the privilege that only nobles could carry swords; the implementation of the policy of levying taxes according to the number of acres of land was equivalent to recognizing the legality of "private land", and the landlord class of the Qin state began to rise.
In 400 BC, Duke Jian of Qin died, and his son succeeded him as Duke Hui of Qin II.
During the reign of Duke Hui of Qin II, he raised an army of 500,000 in an attempt to seize the territory of the State of Wei in eastern Guanzhong to inherit the State of Jin, but the Qin army was low in combat effectiveness and was defeated by the 50,000 Wei army led by Wu Qi. After that, Wu Qi continued to severely suppress the State of Qin, and if it were not for the persecution of Wu Qi during the reign of Marquis Wu of Wei, the State of Qin would almost be in danger of being destroyed.
In 387 BC, Duke Hui of Qin II died, and his son was still young, and he succeeded to the throne as Duke of Qin, only two years old, and was regent by his mother.
At this time, another lineage, Qin Zhaozi and Qin Linggong's son Gongzi Lian, had been in the State of Wei for many years, and at this time it was the years of wealth and experience, and the nobles of the Qin State welcomed Gongzi Lian. At this time, Gongzi Lian was forty years old, his cousin Qin Chugong was two years old, and Qin Chugong's mother was in her twenties. When Gongzi Lian was taken the throne, now, the time for revenge has arrived.
Gongzi Lian returned from the State of Wei, and Qin Chugong's mother hurriedly sent troops to the east of Guanzhong to block it, but Gongzi Lian detoured north of Guanzhong and advanced all the way to the Qin capital Jingyang, and in 385 BC, the nobles of the Qin State revolted, killed Qin Chugong and his mother, threw themselves into the abyss, and set up Gongzi Lian as a tribute to Qin.
The title returned to the Qin Zhaozi lineage.
After Duke Xian of Qin succeeded to the throne, in order to get rid of the involvement of the old nobles, the capital continued to move eastward, moving to Liyang in the east of Guanzhong, which is now the aircraft city of Yanliang.
The son of Qin Xiangong, the famous Duke Xiao of Qin, implemented the Shang Martingale Transformation Law in the Qin capital Of Oak Yang, and the poor and weak Qin State soared in strength and became a first-class power.
After that, Shang Martin offered advice, and the Qin state moved the new capital xianyang in central Guanzhong, with a central position, and began the process of unification.
