Russian conquest of Central Asia

In the 16th century, the Tsardom of Russia embarked on a campaign to expand the Russian frontier to the east. This effort continued until the 19th century under the Russian Empire, when the Imperial Russian Army succeeded in conquering all of Central Asia. The majority of this land became known as Russian Turkestan—the name "Turkestan" was used to refer to the area due to the fact that the vast majority of the population was inhabited by Turkic peoples, excluding the Tajiks, who are ethnolinguistically Iranian people; the ethnolinguistic map of the region has not changed significantly since then. Upon witnessing Russia's absorption of the various Central Asian realms, the British Empire sought to reinforce India, triggering the Great Game, which ended when both sides eventually designated Afghanistan as a neutral buffer zone.

Although the Russian Empire collapsed during World War I, the Russian sphere of influence remained in what was Soviet Central Asia until 1991. This region now comprises Kazakhstan in the north, Uzbekistan in the centre, Kyrgyzstan in the east, Tajikistan in the southeast, and Turkmenistan in the southwest; the Russian language is still recognized in some capacity in many of these countries.
