The settlement of Akmoly, also known as Akmolinsky prikaz, was established on the Ishim River in 1830 as the seat of an okrug by a unit of the Siberian Cossacks headed by Fyodor Shubin. The name was possibly given after a local landmark—Akmola literally means "a white grave" in Kazakh language—although this theory is not universally accepted. In 1832, the settlement was granted town status and named Akmolinsk. The fairly advantageous position of the town was clear as early as 1863 in an abstract from the Geographic and Statistical Dictionary of the Russian Empire. It describes how picket roads and lines connected this geographic centre to Kargaly in the East, Aktau fort in the South and through Atbasar to Kokshetau in the West. In 1838, at the height of the great national and liberation movement headed by Kenesary Khan, Akmolinsk fortress was burned. After the repression of the liberation movement, the fortress was rebuilt. On 16 July 1863, Akmolinsk was officially declared an uyezd town. During the rapid development of the Russian capitalist market, the huge Saryarka — Steppe and Lakes of Northern Kazakhstan were actively exploited by the colonial administration. To draft regulation governing the Kazakh Steppe the Government of the Russian Empire formed Steppe Commission in 1865. On 21 October 1868, Tsar Alexander II of Russia signed a draft Regulation on governing Turgay Oblast (Russian Empire), Ural Oblast (Russian Empire), Akmolinsk Oblast (Russian Empire) and Semipalatinsk Oblast, Russias. In 1869, Akmolinsk external district and department were cancelled, and Akmolinsk became the centre of the newly established Akmolinsk Oblast (Russian Empire). In 1879, Major General Dubelt proposed to build a railway between Tyumen and Akmolinsk to the Ministry of Communications of Russia. In the course of the first 30 years of its existence, the population of Akmola numbered a trifle more than 2,000 people. However, over the next 30 years the citys population increased by three times according to volosts and Human settlement of the Akmolinsk Oblast. In 1893, Akmolinsk was an uyezd with a 6,428 strong population, 3 church (building), 5 schools and colleges and 3 Factory.
