The Yuan Dynasty was the dynasty with the largest land area in the history of China, with a land area of13.72 million square kilometers. The territory of the Yuan Dynasty started from the Sea of Japan in the east, the South China Sea in the south, Tianshan Mountain in the west and Lake Baikal in the north. ? The whole country is divided into the Gyeonggi area under the direct administration of Zhongshu, the Tubo area under the direct administration of Zheng Xuan Academy and ten Zhongshu provinces.

The predecessor of the Yuan Dynasty was Great Mongolia. Genghis Khan Temujin owned the north-south desert and forest area when 1206 was founded. After successive generations of Mongolian Khan's management and three voyages to the Western Seas, its territory stretches from the Sea of Japan and the East China Sea in the east, the Black Sea and the Mediterranean Sea in the west, Siberia in the north and the Persian Gulf in the south, and it has established a superpower spanning Asia and Europe.

The vassal States of the Yuan Dynasty:

The vassal states of the Yuan Dynasty were Korea, Myanmar, Annan, Zhancheng and the four great khanates. Among them, there are two directly subordinate vassal States, namely, the Koryo Dynasty and the Bagan Dynasty in Myanmar, which are divided into the eastbound province and the central province in Myanmar. During Yuan Wenzong's reign, when compiling the Grand Ceremony of Shi Jing, Qincha Khanate, Chahetai Khanate and Yili Khanate were listed as vassal states of the Yuan Dynasty.

Korea, also known as the Korean dynasty and the royal family Korea, is one of the ancient countries on the Korean peninsula. In 9 18 AD, the subordinate of Gong, the monarch of Taifeng, revolted and established Wang Jianwei. In 935, Silla was merged, and after the Baekje was destroyed in 936, the "unification of the three Koreas" was realized. The capital of South Korea is Beijing. The territory is roughly equivalent to the south-central part of the Korean peninsula today.

Annan is an ancient name of Vietnam, named after Khufu of Annan in the Tang Dynasty. It has been the territory of China since the Qin Dynasty in China in the 3rd century BC. By the time of the Five Dynasties and Ten Kingdoms, Wu Quan was separated, Annan was separated from the Southern Han Dynasty, and the Northern Song Dynasty was unable to be unified and officially independent. Since then, Viet Nam has been a vassal state of China for a long time.

The occupation of ChampaKingdom is the occupation of the country, the occupation of the wave, and the search for the wave. Located in the southeast of Indo-China Peninsula, it starts from Hengshan Pass in Ha Tinh Province in the north and reaches Pan Lang and Li Pan in Pingshun Province in the south. The king made up for Indra.

There are only two people in the smallest country in the world.

Speaking of the smallest country in the world, anyone who has studied geography knows that it is the Vatican, a small inland city-state in Europe. The Vatican covers an area of 0.44 square kilometers and has a population of more than 800. If a small country is defined by its population, there are many countries with a smaller population than the Vatican, but they are not recognized by the international community and are private countries, the smallest of which is the Kingdom of Northern Sudan. Strictly speaking, the Kingdom of Northern Sudan does not belong to the state. Why do you say that? Because the population of this country is too small, there are only two people. Everyone will be very curious. How did this happen? Don't worry, let Bian Xiao explain it to you slowly. We heard that Sudan was divided into two countries on 20 1 1. One is the Republic of South Sudan. ?

One is the Republic of Sudan. So, what about the Kingdom of Northern Sudan? To put it simply, it is a country established by a pair of American fathers and daughters who picked up a piece of 2060 square kilometers of landless land for nothing. As we all know, the Antarctic continent is ownerless, and there are international conventions. No country is allowed to occupy it, otherwise it would have been carved up by other countries. However, just in Africa, there is another place where there is no land, and neighboring countries don't want it. Finally, it was finally ignored by American father and daughter and established a private country. The rejected place is Birta Will. Located on the border between Sudan and Egypt, it is mostly desert and mountainous, and it is dry all the year round. It is a barren land, so it is rejected by many countries. ?

Since ancient times, because of territorial and border issues, all countries have negotiated treaties. If no agreement can be reached, it will lead to war. So why didn't bir tawil cause controversy? Is the land barren? Of course not. When it comes to this issue, we have to talk about the dispute between Sudan and Egypt. Egypt and Sudan were once British colonies. In order to facilitate management, Britain demarcated Sudan and Egypt. For convenience, it simply uses latitude and longitude to divide the boundary. 1899, Egypt and Sudan are bounded by the 22nd parallel of north latitude. ?

Bir tawil, south of the border, belongs to Sudan, but after the division, the contradiction comes out, because there are some Egyptian nomadic tribes in Bir tawil, and there is a place in the north outside the border called Halabi, but there are nomadic tribes in Sudan. Because bir tawil and Halabi are both dissatisfied with the boundary demarcated by Britain, they often have disputes. Britain finally gave Birta Ville to Egypt and Hala to Sudan. I thought it was peace, but there were still contradictions. Halabi is 65,438+00 times larger than Birta, and oil has been discovered. Sudan is certainly satisfied, but Egypt is not. After the end of World War II, Britain's power gradually weakened. Egypt and Sudan became independent one after another, and Britain just gave up?

Therefore, because of the territorial issue, even though Egypt now controls Halabi, Sudan still has sovereignty. Both countries are afraid that this barren land will be divided into their own countries. Bir tawil is like a hot potato, and no one wants to answer it. In 20 12, American Heaton failed to run for Senate in Virginia. Before the election, his 6-year-old daughter asked him if he could be a real princess. Heaton agreed and didn't try to cheat her daughter. Because I didn't want to spill the beans in front of my daughter, I looked up the ownerless land on the Internet and just found Birta Will. ?

So Heaton applied to Egypt for this barren land. Unexpectedly, Egypt readily agreed. Heaton and her daughter designed this national flag, planted it in Birta, and named it the Kingdom of North Sudan. Heaton claims to be king, and her daughter Emily is a princess. But strictly speaking, although Heaton has established a private country, it still needs the approval of neighboring countries and the United Nations. Although there have been private countries in history, it is a comfort to oneself and is not authoritative. Heaton's deep love for her daughter still makes us very moved!

Ten countries with the largest area

The ranking of territorial area of countries in the world refers to the latest ranking of land area of countries. Countries with an area of 10 include Russia, Canada, China, the United States, Brazil, Australia, India, Argentina, Kazakhstan and Algeria.

The area within the scope of land ownership. Therefore, once the land ownership boundary is determined, the land area is also determined. If the boundary range on the land ownership certificate is consistent with the field but the area is inconsistent, the boundary range shall prevail and the land area data shall be revised. The principle of area measurement is: take the map as the basic control, measure by frame, adjust according to the area ratio, and summarize gradually from bottom to top.

According to international practice, the national area is called "total area", which means: total area = land area+national fresh water surface area.
