阴山以南地区在很早就有猿人和古人类活动、生息和繁衍，而“河套人”是内蒙古地区有名称的最早者。新石器时代有西戎、华夏及东夷族迁入，土著氏部落的成份复杂起来。夏商周时期的文化遗存，以在西辽河上游和黄河流域发现的较多。东周以前，内蒙古南部地区的政治、经济、文化是高于其他地区的，社会发展也是不平衡的。 In the area south of Yinshan, there were early ape-man and ancient human activities that gave birth and flourished. However, “Hetao people” are the earliest names in Inner Mongolia. In the Neolithic period, there were immigrants from Xi Rong, Huaxia and Dong Yi, and the composition of the indigenous tribes was complicated. Cultural relics during the Xia, Shang and Zhou dynasties were found more frequently in the upper reaches of the West Liao River and in the Yellow River basin. Before the Eastern Zhou Dynasty, politics, economy and culture in southern Inner Mongolia were higher than those in other regions, and social development was uneven.
