Most dynastic regimes in ancient China were established by the Han chinese, who dominated almost the entire historical process of the Chinese nation. However, there are always exceptions to everything, such as the two great unified dynasties of the Yuan Dynasty and the Qing Dynasty, which are the regimes established after the grassland peoples laid the Foundation for the Central Plains, but the Yuan Dynasty was relatively short-lived, and the Qing Dynasty lasted longer.
They were originally steppe peoples, but after they became strong, they were naturally not willing to continue to stay in a remote place. For example, the Mongols, when the Song Dynasty became weak, came to fight, destroyed the Southern Song Dynasty, and established the Yuan Dynasty on their own; although they were later expelled back to the steppe by Zhu Yuanzhang, when the Qing army entered the customs, the Mongols maintained close ties with them, and the Qing Dynasty has always had a tradition of marrying Mongolian tribes.
During the Qing Dynasty, the area of our country was relatively large, and the current Mongolia was an introspection of our country during the Qing Dynasty. However, at that time, it was very large, in the north of our country, bordering foreign countries, and its own independent royal family. When the Qing Dynasty was strong, Mongolia could be said to be a vassal of the Qing Dynasty.
But in modern times, Mongolia was divided into inside and outside, after the outbreak of modern wars, the rule of the Qing government began to decline, so it also signed many treaties, of which Mongolia gained the support of certain forces, in 1911, that is, the same year that the Qing Dynasty declared its demise, it became independent, but it did not begin to gain world recognition until 50 years later.
Mongolia's territory, although it can not be compared with ours, but in fact, it is also considered to be vast, and its domestic population density is really very small, according to 2018 data, its domestic square kilometer, an average of only 2 people. In 2015, the population exceeded 3 million.
Although its domestic population is only more than 3 million, the ratio of men to women is normal, and there are relatively modern marriage laws, polygamy is still allowed in some parts of the country. A lot of times this choice is to increase the population, and they are no exception, but for now, it seems that the results are average.
And its domestic grasslands, mountains, lakes are more, more rivers, so there are still many people who have followed the tradition of the ancestors, to herd cattle and horses animal husbandry for a living, obviously this kind of work has not been welcomed by contemporary young people, so there are many people who leave their hometowns to find jobs in big cities.
Moreover, even if a man can marry several women, the average woman is not willing to choose this marriage model. In fact, Mongolian women are still more capable, and can even be said to be better than men. They come out to work, and in every important sector, the proportion of women is high, in addition to which women have to take care of the housework.
Because many local men do not take care of their own affairs, it is a woman's business to have children, take care of children and the elderly, and run the family. This has also led to the reluctance of some excellent Mongolian girls to marry, believing that being single is happier than getting married. Obviously, they will only change their minds if their rights are guaranteed.
