The emergence of trademarks is accompanied by the development of commercial trade. In the early days of simple and fragmented commercial trade, consumers did not need to identify specific operators through trademarks. They traded directly with producers. With the expansion of production scale, the distance between producers and consumers is getting farther and farther, and consumers often need to buy goods from producers through middlemen. During this period, commercial activities were under the strict control of the government, and trademarks were one of the main tools used by the government and guild organizations to control commercial activities. The "trademark" at this time was a management mark and a responsibility mark. On the one hand, the government requires commercial entities to use specific mandatory signs on specific products and not to change the signs they use at will, thereby strengthening the qualification control of commercial entities; on the other hand, it also requires these signs to have identification and Different functions, because they are the basis for tracing liability for defective goods and taxing them. In addition to the government, guilds were also an important force in controlling business activities. Especially in Europe from the 12th to the 15th century, guilds achieved unprecedented development. In order to facilitate management, the guild stipulated that when a person became a skilled craftsman, he must choose a mark and use that mark on all goods made by him, and he could only use that mark throughout his life. With the development of history, the government gradually relaxed controls on commercial activities, and the guild system gradually withdrew from the stage of history. Merchants and craftsmen were no longer forced to use specific marks. However, the arrival of the Industrial Revolution led to the development of inter-regional trade. With the prosperity and scale of social production, many businessmen are willing to continue to use marks on the products they produce to indicate the source of the products and commend their quality, thus giving these marks a completely new function.
