カザフ・ハン国
Kasym, son of Janibek, became the Khan in 1511. Under his rule, the Kazakh Khanate reached its greatest strength so much that the Nogai Horde, which occupied the territory of modern Western Kazakhstan, became its number one enemy. Kasym successfully captured the Nogai capital Saray-Juk in 1520, pushing the Nogai Horde to the Astrakhan Khanate. Under Kasym Khan, the borders of the Kazakh Khanate expanded, the population reached 1 million people. It was during the reign of Kasym Khan that the Kazakh Khanate gained fame and political weight in the modern Euro-Asian arena. Kasym Khan also became a major patron of the arts, literature, and religion, allowing Islam to hold great political and sociocultural importance among Kazakh society. Under his reign, the Tsardom of Russia also became the first major state to establish diplomatic relations with the Kazakh Khanate. Upon doing so, Kasym Khan established his reputation as a successful leader, as his empire became known as a up-and-coming political entity to the Western Europe.
