When the Mongols took over China, a lot of things changed. Art was one of them. From fabrics and textiles, to sculptures and music, Mongolian art is a thing to behold. One may not think it, but the Mongolians' invasion of China led to a cultural boom. The Mongols accepted most religions into their lives except for a few, and their art shows that of different gods and animals they praised. (See two pictures below) In fact, most art before the 20th century was focused on religion and the making of 'Thangka's', large paintings on cotton or silk depicting Buddhist Deities or scenes from religious writing.
Mongolian people also take pride in their literature. From a very early time, The Mongols had their own language that they would attempt to force onto other cultures (without much success) and their most prized piece of writing (Seen below) is a text called 'The Secret History of The Mongols' and was published by an unknown author in 1227A.D. This is some time after Ghengis Khans death earlier in the year.
