Astrakhan is in the Volga Delta, which is rich in sturgeon and exotic plants. The fertile area formerly contained the capitals of Khazaria and the Golden Horde. Astrakhan was first mentioned by travelers in the early 13th century as Xacitarxan. Tamerlane burnt it to the ground in 1395 during his war with the Golden Horde. From 1459 to 1556, Xacitarxan was the capital of Astrakhan Khanate. The ruins of this medieval settlement were found by archaeologists 12 km upstream from the modern-day city.
