In the 18th century it became part of the khanate of Kokand, and in 1876 Andijon was captured by the Russians. In 1898 it was the scene of an abortive native rebellion against tsarist rule. Andijon is subject to frequent earth tremors and was leveled by an earthquake in 1902 that took more than 4,000 lives.
