Russian Turkestan was the western part of Turkestan within the Russian Empire’s Central Asian territories, and was administered as a Krai or Governor-Generalship. It comprised the oasis region to the south of the Kazakh Steppe, but not the protectorates of the Emirate of Bukhara and the Khanate of Khiva. It was populated by speakers of Russian, Uzbek, Kazakh, Kyrgyz, and Tajik.

The Emirate of Bukhara was a Muslim polity in Central Asia that existed from 1785 to 1920 in what is now Uzbekistan, Tajikistan, Turkmenistan and Kazakhstan. It occupied the land between the Amu Darya and Syr Darya rivers, known formerly as Transoxiana. Its core territory was the fertile land along the lower Zarafshon river, and its urban centres were the ancient cities of Samarqand and the emirate's capital, Bukhara. It was contemporaneous with the Khanate of Khiva to the west, in Khwarazm, and the Khanate of Kokand to the east, in Fergana. In 1920, it ceased to exist with the establishment of the Bukharan People's Soviet Republic.
