Mongolia

The recorded history of ancient Mongolia dates to the third century BC when the Xiongnu came to power among many other nomadic tribes. Due to illiteracy and their nomadic lifestyle, little was recorded by the Xiongnu of themselves; they first appear in recorded Chinese history as "barbarians" against whom the walls were built. Those walls later became known as the Great Wall of China. The Xiongnu were eventually defeated by China's Han Dynasty in AD 89. Xiongnu history is controversial. Different historians attribute them to several quite different ethnic groups. Some claim that Xiongnu is cognate to Hun Nu or even that these are basically the same group known as Huns centuries later in Europe, but both claims are contested. There have been several empires in Mongolia after the Xiongnu. The first strong state to emerge was the First Turkic Khaganate in AD 552 with its capital at Ötüken (modern-day Ordu-Baliq). However, due to political infighting, this empire fragmented into the Eastern Turkic Khaganate with its capital at Ötüken, and the Western Turkic Khaganate with its capital at Suyab (near Bishkek in modern-day Kyrgyzstan), in AD 603. Both of these states were eventually defeated by China's Tang Dynasty; the Eastern Turkic Khaganate fell in AD 630, while the Western Turkic Khaganate fell in AD 657. The next strong empire to emerge was the Uyghur Khaganate, with its capital Har Bulgas (Khar Bulgas or Xar Bulgas) near Har Horin....
