In the 9th century AD, the emperor gradually lost the power to manage government affairs, but Guan Bai, who was inherited by Fujiwara, exercised power instead of the emperor. During this period, under the rule of Fujiwara, Japanese citizens lived and worked in peace and contentment, which is called "Heian period" in history. During this period, the Japanese ruling class gradually became corrupt, extorting and cruelly squeezing its subjects, and smaller tenants could only give their property to the big landlord who had the tax-free right in North Korea at that time. These strongmen have a lot of land and wealth, but they also have their own small-scale army. During this period, a new class-samurai class appeared. At the same time, the power in the hands of court officials and bureaucrats gradually fell into the hands of feudal landlords.

Among the feudal manor owners, the largest are descendants of Emperor Kanmu Ping (Huanwuping family) and Qinghe Emperor (Qinghe Genji). The two of them made great contributions to the emperor in suppressing rebellion and peasant riots, and paid huge expenses for the royal family and officials, thus gaining the trust of the royal family and holding the central government in Fujiwara's hands.

1 155, the emperor ascended the throne was in crisis. Genji Pinghe was loyal to different emperors, and finally fought for them (the Battle of Baoyuan). Genji was defeated and finally monopolized the power, excluding Genji.

1159-1160, a direct war broke out between the two families in Pingyuan. In the end, Shi Ping won and pursued Genji mercilessly, but he did not eradicate the root cause. ...

1 180, Emperor Andrew, the grandson of Pingshou, ascended the throne. After 20 years of rest, Genji challenged Hirazuka again. The Battle of Hirakawa lasted for five years and ended with the victory of Genji and Fujiwara against Hirakawa. In the end, imperial officials came to worship foreign generals, seized power, moved Japan's political center to Kamakura, and established the Kamakura shogunate.

1 199, Yuan Lai Chao died, and Beitiao, the descendant of Ping, came to power. His son, Kitajima Yi Shi, assassinated the descendants of Yuan Laichao, and made Yuan come to Beijing as a 2-year-old general, at the same time holding real power by himself. In the Tokugawa era of Kamakura, Mongols invaded Japan. Although Japan won, it greatly consumed the strength of the shogunate. In addition, the samurai who were dissatisfied with the Tokugawa era jointly attacked Kamakura in the name of restoring the emperor's rights, and the Kamakura shogunate perished in 14 1.

After the rebellion, the warlord asked Daigo to appoint him as a general, but he was rejected. So Zuyizun turned to Guangwudi (commonly known as the Northern Dynasties), while Weiqi Daigo fled to the south and established its capital in Yoshino (commonly known as the Southern Dynasties), and the era of Japanese Southern and Northern Dynasties began.

The "North-South Rebellion" lasted for 57 years and ended with the victory of Zumu, who established the Muromachi shogunate.

After the unification of Japan and Japan, all meritorious ministers were made princes, which led to the excessive influence of domestic princes. Until the first year of Ren Ying (1467), the famous Prince Zishan and General Hosokawa Morihiro finally went to war in Kyoto, which was the "Ren Ying Rebellion" that lasted for eleven years. In the "Ren Ying's Rebellion", the shogunate existed in name only, and the ministers played politics, and the heroes rose together. Peasant riots are frequent, and powerful people all over the country are independent. The most famous "Warring States Period" in Japanese history began. ...

During the Warring States period, the smoke of Japan stood side by side, and all the famous soldiers competed for each other. Among them, Zhang Wei's Lord Nonomura Yongzhitian (1534- 1582) rose suddenly. /kloc-in 0/560, he killed Imagawa Yoshimoto, whose troops were ten times his own, and then seized the rice-leaf mountain city, which was easy to defend but difficult to attack, and renamed it "Gifu", and awarded the seal of "Building the world by force". This is the Beno Temple incident that shocked Japan.

Later, another Nobunaga, who fought in China (the place name of Japan), quickly returned to Kyoto (later Toyotomi Hideyoshi) to destroy Akechi Mitsuhide, and unified Japan in the following years, and was given the surname Toyotomi by the Emperor. However, Toyotomi Hideyoshi was not satisfied with the achievement of unifying Japan. He came from a humble background and wanted to incorporate the whole East Asia into the territory of Japan. For this reason, he invaded Korea twice, but both were defeated by the Chinese and Korean Coalition forces. 1598, Toyotomi Hideyoshi died of grief and anger. After Toyotomi Hideyoshi's death, Tokugawa Ieyasu, a warlord, took advantage of the contradiction between Toyotomi Hideyoshi's civil servants and military commanders to launch a joint campaign with Guan Yuan. Tokugawa Ieyasu and his party won, and Konka took this opportunity to gain political power. 1603, the edo shogunate (also known as Tokugawa shogunate) was established.

After Tokugawa Ieyasu destroyed the Toyotomi family, Japan was reunited. The Tokugawa shogunate gradually became corrupt in the middle and late period, and the ruling class brutally exploited the lower classes. Before that, there were riots all over Japan in the Tokugawa era, which eventually developed into a large-scale fund-raising movement. Finally, Tokugawa Yoshinobu, the Tokugawa shogunate15th generation general, announced that he would return the political power to the reformist Meiji Emperor, ending Japanese feudal rule through the Meiji Restoration and embarking on the capitalist road.
