The significance of "Dahua" and "innovation": it marks Japan's transition from slave society to feudal society.

Since 646, Japan has carried out a series of reforms, called "innovation" in history. It is the result of the development of internal contradictions in Japanese slave society. On the one hand, it is the contradiction between working people and emperors, slave owners and nobles. In addition to slaves and a large number of people, Yamato people also have farmers, who are also oppressed and exploited by emperors and slave owners and nobles. Royal aristocrats constantly occupy land, forcing working people to become people, and class contradictions are becoming more and more acute. In order to rule the working people, the royal family and nobles need to concentrate on consolidating the political power. On the other hand, it is the contradiction between the royal family and the nobility. At that time, the emperor had not mastered the highest ownership of the land in the country, and his direct control was initially limited to his own territory and the residents above. The emperor and nobles competed for land and people. For example, many mainland immigrants with advanced technology are under the control of the royal family, and the nobles hope to take them into their own hands. In the process of competition, the ruling power of the central government has gradually expanded to local areas, and the trend of struggle is to continuously strengthen imperial power and establish centralization centered on the royal family. However, the nobles who controlled a large amount of land and people opposed centralization. In the 7th century, the most powerful aristocrat was Sue. In 645, the prince, the eldest brother who demanded innovation, joined forces with the noble sickle foot to launch a top-down coup, killed the Su family, and established the country name Dahua. The Yamato era is over. In 646, Emperor Kotoku changed the cloth into a new imperial edict. This is the change from big to new.

Emperor Kotoku (about 596 ~ 654) was the Japanese emperor. His real name is Guang. He was born in the Japanese royal family, the son of Elvis Presley, and the same mother and brother as the Emperor. 12, June 645, Zhong Ge, et al., a new faction of the Japanese army, took advantage of the aristocratic slave owners' power to launch a coup. Su I entered the deer and was stabbed to death by a North Korean messenger in Taijitang, a bird in Beijing. The next day, his father Su I committed suicide. 14 years, the reformists forced the emperor to abdicate, and his younger brother succeeded to the throne, known as Emperor Kotoku, and his eldest brother held real power. After he acceded to the throne, Zhong Xiong was appointed as the Crown Prince, as the Minister of the Interior, Abe Malu as the Minister of the Left, Su I and Kurayamada Ishikawa Malu as the Ministers of the Right, and Gao Xiang and Min Monk, who were studying in China, were appointed as Dr. Guo (political adviser). In 646, on the first day of the first month, imitating China, the company officially established the title "Dahua" (the earliest Japanese title) and established Nanpu (now Osaka) as its capital. Supporting the reform advocated by Brother Zhong and others, promulgating the imperial edict of innovation, and carrying out the reform is called "Dahua Innovation" in history. The innovation measures violated the political and economic interests of the nobles and caused their fierce resistance. The eldest brother of the ancients lived in Yoshino in seclusion, rebelled and the plot was exposed. In 649, the right minister failed in rebellion and committed suicide. After a long struggle, the reform results were finally preserved. Dahua innovation
