Brief History of Kazakhstan
Nomadic tribes have been living in the region that is now Kazakhstan since the first century BC. From the fourth century AD through the beginning of the 13th century, the territory of Kazakhstan was ruled by a series of nomadic nations. Following the Mongolian invasion in the early 13th century, administrative districts were established under the Mongol Empire, which eventually became the territories of the Kazakh Khanate. The major medieval cities of Taraz and Turkestan were founded along the northern route of the Great Silk Road during this period.
Traditional nomadic life on the vast steppe and semi-desert lands was characterized by a constant search for new pasture to support the livestock-based economy. The Kazakhs emerged from a mixture of tribes living in the region in about the 15th century, and by the middle of the 16th century had developed a common language, culture, and economy. In the early 1600s, the Kazakh Khanate separated into the Senior, Middle, and Junior Hordes-confederations based on extended family networks. Political disunion, competition among the hordes, and a lack of an internal market weakened the Kazakh Khanate. The beginning of the 18th century marked the zenith of the Kazakh Khanate. The following 150 years saw the gradual colonization of the Kazakh-controlled territories by Tsarist Russia.
The process of colonization was a combination of voluntary integration into the Russian Empire and outright seizure. The Junior Horde and part of the Middle Horde signed treaties of protection with Russia in the 1730s and 1740s. Major parts of the northeast and central Kazakh territories were incorporated into the Russian Empire by 1840. With the Russian seizure of territories belonging to the Senior Horde in the 1860s, the Tsars effectively ruled over most of the territory belonging to what is now the Republic of Kazakhstan.
