Оренбургская губерния
Although Russia had been pushing south into the steppes from Astrakhan and Orenburg since the failed Khivan expedition of Peter the Great in 1717, the beginning of the Russian conquest of Turkestan is normally dated to 1865. That year the Russian forces took the city of Tashkent under the leadership of General Mikhail Chernyayev expanding the territories of Turkestan Oblast (part of Orenburg Governorate-General). Chernyayev had exceeded his orders (he only had 3,000 men under his command at the time) but Saint Petersburg recognized the annexation in any case. This was swiftly followed by the conquest of Khodzhent, Dzhizak and Ura-Tyube, culminating in the annexation of Samarkand and the surrounding region on the Zeravshan River from the Emirate of Bukhara in 1868 forming the Zeravsh Special Okrug of Turkestan.
