The Polo family were some of the first Europeans to meet and describe the great Mongol rulers of the time , like Kublai Khan and Barka Khan . But who were the Mongols, and what was the Mongol Empire ?
In the beginning , the Mongols were different groups of people who moved around Central Asia . They were men and women who rode form place to place to look for food for their animals. They lived in warm tents called gers which were made from animal skins.
In 1206 the great Mongol leader Genghis Khan brought together these different Mongol groups and conquered the north of China and much of Central Asia. By the time of Genghis Khan's grandson Kublai Khan, the Mongols ruled a huge empire. It went from the Sea of Japan in the east to modern-day Turkey and Hungary in the west. It was the largest land empire of all time. Just 200,000 Mongols ruled more than 100 million people. The empire went across 22 per cent of the world's land!
There were four different areas of the Mongol Empire at this, and Kublai Khan ruled over the Empire of the Great Khan. This started at Lake Baikal in the north and went down through China to the modern-day country of Myanmar in the south. It also went from Korea in the east to Tibet in the west.
