History: Central Asia, 140 Years Ago

An alternative method is to define the region based on ethnicity, and in particular, areas populated by Eastern Turkic, Eastern Iranian, or Mongolian peoples. These areas include Xinjiang Uyghur Autonomous Region, the Turkic regions of southern Siberia, the five republics, and Afghan Turkestan. Afghanistan as a whole, the Northern Areas of Pakistan and the Kashmir Valley may also be included. The Tibetans and Ladakhi are also included. Insofar, most of the mentioned peoples are considered the "indigenous" peoples of the vast region.
There are several places that claim to be the geographic center of Asia, for example Kyzyl, the capital of Tuva in the Russian Federation, and a village 200 miles (320 km) north of Ürümqi, the capital of the Xinjiang region of China.
