I support this statement because the Mongols killed millions of people during their conquest which makes them uncivilized.

Alauddin Khilji : When the Mongols kept trying to conqueror India in their many tries, I had made 20000 Mongol prisoners.

Alauddin Khilji: By my military brilliance, managed to defeat the Mongols not once, but five times, and avoided defeat a sixth time even when taken by surprise, as the Mongols attacked with massive forces.

Alauddin Khilji: Mongols were barbarians, they keep coming back even though have been beaten by me and my army. The Mongols kept trying and trying to get land in India I was a great general.

They made roads, bridges, and postal stations and also extended the Grand Canal in China. They also protected the Silk Road.

Eventhough mongols were ruthless they had rules, trade, religion, communication, and guidelines for behaviors.

The Mongols built some Capitals, for example, they made Karakorum and Khan Bhalik (Site of Beijing)

Anyone who resisted would be annihilated and they were fearsome plunders.

Even though Mongols had good horsemen, they killed millions and millions of people during their conquest.

Mongols would scare people away with psychological warfare to terrify their enemy. This made everyone leave when they heard the Mongols were coming
