[4] The first Rus' traders and soldiers began to appear on the northwestern edge of modern Kazakhstan territory in the early 16th century, when Cossacks established the forts that later became the cities of Oral (Ural'sk, est.Russian imperial authorities followed and were able to seize Kazakh territory because the local khanates were preoccupied by a war with Kalmyks (Oirats, Dzungars).In 1824, Siberian Cossacks from Omsk founded a fortress on the upper Ishim River named Akmolinsk, which is known today as Astana, capital of Kazakhstan.In the 1860s General Mikhail Chernyayev conquered the only towns that existed in Kazakhstan before the Russian conquest Hazrat-e Turkestan, Taraz and Shymkent that belonged to the Khanate of Kokand.Analysis of data on migrants who arrived during the Stolypin agrarian reform (1906-1912) on the territory of Kazakhstan shows that 83.1% of the settlers were from Ukraine, the rest came from the southern regions of Russia (16.8%).In 1918-1931 Basmachi Revolt affected areas of southern Kazakh SSR often taking a form of an ethnic conflict between Russian and Ukrainian farmers and native Muslim nomads.Thousands of Russian settlers are thought to have been killed by the Kazakhs in the violence and this was followed by equally bloody reprisals against the nomadic population by the Red Army.The Kazakh Autonomous Soviet Socialist Republic was established as part of the RSFSR - the process was not straightforward and included disputes over territories.These migrants founded mining towns which quickly grew to become major industrial centers such as Karaganda (1934), Zhezkazgan (1938), Temirtau (1945) and Ekibastuz (1948).Still more settlers came in the late 1960s and 70s, when the government paid bonuses to workers participating in a program to relocate Soviet industry close to the extensive coal, gas, and oil deposits of Central Asia.Following several incidents of ethnic unrest in 1989, Kolbin was replaced by Nursultan Nazarbayev who following the dissolution of the Soviet Union became the president of independent Kazakhstan.[12] A major factor that contributed to the alienation of Russians and the increase of inter-ethnic tensions in post-Soviet Kazakhstan was the government's language policy.[16] At the beginning of his presidency in 2000, Vladimir Putin met with leaders of the Russian community in Kazakhstan who explained to him the situation they faced in the country.
