カザフ・ハン国
Gradual decline, disintegration and accession of Kazakh territories into the Russian Empire began in the mid-18th and ended in the second part of the 19th century. By the mid-18th century, as a result of long-lasting armed conflicts with Dzungars and Oirats, the Kazakh Khanate had started to decline and further disintegrate into three Jüzes, which formerly constituted the Kazakh Khanate in a confederate form.
