The sea ban began in the Ming Dynasty, not the Yuan. The Yuan Dynasty implemented a policy of free t

The sea ban of the Yuan Dynasty rose and fell, from the end of the Yuan Shizu to the end of the second year of Yingzong Zhizhi (1322), during which there were four sea bans. The first sea ban began in August of the 29th year of the Yuan Dynasty (1292), when Shizu "conquered Java and temporarily banned the voyagers of Zhejiang, Guangdong and Fujian", and ended in the 31st year of the Yuan Dynasty (1294). The second sea ban began in the seventh year of Dade (1303) with the abolition of the city ship organization by "prohibiting merchants from going to the sea", and in the first year of Wuzong (1308), "the Quanfu was restored and the city was rectified."

Since the middle of the Tang Dynasty, the city ship agency has been the main institution for the management of overseas **, and its rise and fall are closely related to the sea ban, therefore, the "rectification of the city ship department" indicates the end of the second sea ban. The third sea ban began with the abolition of the city ship promotion division in the fourth year of Wuzong (1311), and the history records that "until the fourth year of the year, the next ship is banned". In July of the first year of Renzong's Yankun (1314), "the edict opened the ban on the next city" and re-established the city's ship.

The last sea ban began in April of the seventh year of Yuan Yanyou (1320) with Yingzong's "dismissal of the city and the ban on the Jia people", and in March of the second year of Yingzong's reign (1322), "the fourth sea ban ended with the re-establishment of the city of Bo Tiju in Quanzhou, Qingyuan, Guangdong, and Sanlu," and the fourth sea ban ended. After the demise of the Yuan, the market did not change again.

The sea ban should have started in the Ming Dynasty, and it should have been to prevent Japanese invaders.

Yes, from the Ming Dynasty.

At the end of the Yuan Dynasty and the beginning of the Ming Dynasty, the Japanese feudal princes divided their territories and attacked each other. The feudal lords, who had lost the war, organized samurai, merchants, and ronins to carry out armed smuggling, looting and harassment in China's coastal areas. In order to prevent the coastal traitors from colluding with the Japanese bandits, Zhu Yuanzhang ordered that "no piece of board should go to sea" and forbade ordinary people to go to sea without permission.

During the Yongle period of the Ming Dynasty, although Zheng He had the feat of going to the West, it was only the tributary ** that was released, and private people were still not allowed to go to sea. Later, with the plague of the Japanese invaders, the maritime ban policy became more and more stringent, which played a role in self-protection, but greatly hindered the development of Sino-foreign exchanges.

Consequences of the maritime ban policy:

1. The foreign policy of restrictive behavior played a certain role in self-defense against the colonialists' aggressive activities in China, but on the other hand, it made China lose its initiative in foreign affairs, so that the progressive handicraft production that had grown up within China's feudal society could not be further developed.

2. The rulers despise science and technology and close off the country, resulting in China's science and technology greatly lagging behind the West.

Good for internal domination, bad for communication.

In the early Ming Dynasty, the sea ban was indeed conducive to the stability of the state power, but later it blocked the foreign world and hindered the development of the commodity economy.

The maritime ban is not conducive to openness and civilized economic exchanges, but it has both advantages and disadvantages to safeguard sovereignty and territorial waters and ensure that the people live and work in peace and contentment.

The purpose of the Ming Dynasty's maritime ban policy was to prevent the invasion of the Japanese invaders, which cut off China from contact with the world and caused the effect of closing the country to the outside world.

The Ming Dynasty originally imposed a sea ban only to prevent bandits and robbers in the coastal areas from colluding with the Japanese to rob the people of the Ming Dynasty. It is a pity that this has also become a major historical foundation for the subsequent closure of the country, and has become the main culprit of the backward world trend of ancient China.

1. Prevent harassment by pirates and pirates in China's coastal areas. At that time, Japan had already begun to intrude and sneak attack China's coastal areas in coastal areas and other areas.

2. Prevent collusion between ** and outsiders**. At that time, the sea was basically carried out locally, in order to prevent losses caused by the abuse of power for personal gain.

The biggest impact of the sea ban is to cause a fatal blow to the sea**, making the lives of the people who rely on the sea for their livelihood more difficult.

The Ming Dynasty's implementation of the sea ban was actually intended to suppress pirates and colonists, and the harassment of the Ming Dynasty's lengthy coastline was the implementation of the political principle of valuing agriculture and suppressing commerce, and the impact was to insulate China from the Age of Discovery.

Answer C: This question tests the student's understanding of the sea ban. Judging from the information of the materials, this mainly reflects that the implementation of the sea ban in the Ming Dynasty was the result of the combined effect of internal and external factors. Others are cautious and wrong. The late branch contains the option C.

The establishment of the Yuan Dynasty City Ship Agency The City Ship Agency was established in the Tang Dynasty. In the second year of Kaiyuan (714)."The city envoy right Wei Zhonglang will be Zhou Qingli, Persian monks and martyrs, etc., to make strange weapons and ingenuity", which shows that at that time there were specialized agencies and officials for the management of the city. After five dynasties and ten local governments, the city ship system in the Song Dynasty entered a mature stage of development.

In the fourth year of Kaibao, after the Northern Song Dynasty destroyed the Southern Han Dynasty, it first set up a city shipping department in Guangzhou, and then set up a city shipping agency in Hangzhou, Mingzhou, Quanzhou, Mizhou and other places, and established a complete and strict overseas management system.
