The Karakhanids were a Turkic dynasty that ruled parts of Central Asia from the 9th to the 13th centuries. They emerged after the decline of the Samanid Empire and controlled regions including modern-day Uzbekistan, Kazakhstan, and Tajikistan. The dynasty is known for its promotion of trade along the Silk Road and for fostering cultural exchanges between the East and West. The Karakhanids played a significant role in the spread of Islam in Central Asia, converting many of the local Turkic tribes. They established a rich cultural legacy, including advancements in literature, science, and architecture, which influenced subsequent empires in the region.
