A report on Inner Mongolia, Mongolia, Xiongnu and Slab-grave culture

Its border includes most of the length of China's border with the country of Mongolia.

The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang.

The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others.

Slab-grave cultural monuments are found in northern, central and eastern Mongolia, Inner Mongolia, Northwest China (Xinjiang region, Qilian Mountains etc.), Manchuria, Lesser Khingan, Buryatia, southern Irkutsk Oblast and southern and central Zabaykalsky Krai.

The most recent graves date from the 6th century BC, and the earliest monuments of the next in time Xiongnu culture belong to the 2nd century BC. The gap is not less than three centuries, and the monuments that would fill this chronological gap are almost unknown.

A Scythian culture, it was identified by excavated artifacts and mummified humans, such as the Siberian Ice Princess, found in the Siberian permafrost, in the Altay Mountains, Kazakhstan and nearby Mongolia.

Before the rise of the Mongols in the 13th century, what is now central and western Inner Mongolia, especially the Hetao region, alternated in control between Chinese agriculturalists in the south, and Xiongnu, Xianbei, Khitan, Jurchen, Tujue, and nomadic Mongol of the north.

Slab Grave cultural monuments are found in Northern, Central and Eastern Mongolia, Inner Mongolia, North-Western China, Southern, Central-Eastern and Southern Baikal territory.

The wheeled vehicles found in the burials of the Afanasevans have been dated to before 2200 BC. Pastoral nomadism and metalworking became more developed with the later Okunev culture (2nd millennium BC), Andronovo culture (2300–1000 BC) and Karasuk culture (1500–300 BC), culminating with the Iron Age Xiongnu Empire in 209 BC. Monuments of the pre-Xiongnu Bronze Age include deer stones, keregsur kurgans, square slab tombs, and rock paintings.

By 1636 most Inner Mongolian tribes had submitted to the Manchus, who founded the Qing dynasty.

Mongolian archaeologists proposed that the Slab Grave Culture people were the ancestors of the Xiongnu, and some scholars have suggested that the Xiongnu may have been the ancestors of the Mongols.
