Europe is so small, why are there so many countries? Please tell me.

For a long time, Europe has been regarded as a region with high happiness index, because we know that their total area is not more than that of China. But there are more than 20 developed countries in Europe, making Europe the most developed continent among several continents. Friends who have been to Europe will find that there are some small towns in Europe that don't look so modern, so why can Europe maintain such a developed level? Over the years, the backwardness of African countries is obvious to all. However, although there are many poor people in Africa, there are also very rich people. During the industrial revolution, Africa was more backward. At that time, however, European predators discovered that America and Asia were rich in natural resources. At the same time, there are veins of gold, silver and diamonds, which have attracted the attention of many national politicians.

So in the past, most of these European countries gradually became rich by plundering other backward areas. Therefore, when plundering so many resources, they can strive to develop their own economy, science and technology and art, and at the same time develop their own military capabilities, manufacture new weapons and strengthen their military strength. But in other words, if Europe didn't have such a strong national strength at that time, it would be impossible for them to reach these remote areas, open up the new continent and bring resources back to China. In fact, we know that wars often broke out in Europe in the past, and the wars lasted for a long time, which usually led to drastic changes in the national territory. Comparing the topography of Asia and Europe, we can find that most parts of Europe are plains and some low mountains and hills. In Asia, there are not only many towering mountains near Mongolia, but also high latitudes near Russia, where the climate is very cold. At the same time, South Asia near the equator is very hot. Therefore, if there is a war in Asia, its reunification will be much more difficult than that in Europe.

This is because its unique conditions, coupled with the economic strength developed in the early days, have given Europe opportunities and possibilities for development. At the same time, Europe's welfare system and various systems are also one hundred years ahead of the world. Therefore, when the European economy is relatively mature, China may be in the period of reform and opening up. So the time difference is hard to make up. At the same time, in many European countries, due to the improvement of the welfare system, many educational and medical problems have been solved for the people. However, due to the large population in China, it is difficult to extend these benefits to some remote mountain villages. At the same time, because it is difficult for them to pay various social security fees, the welfare coverage is not comprehensive enough.
