Shamkhalate of Tarki in the context of Sulak (river)

Makhachkala, previously known as Petrovskoye (1844–1857) and Port-Petrovsk (1857–1921), or by the local Kumyk name of Anji, is the capital and largest city of Dagestan, Russia. The city is located on the Caspian Sea, covering an area of 468.13 square kilometres (180.75 square miles), with a population of over 623,254 residents, while the urban agglomeration covers over 3,712 square kilometres (1,433 square miles), with a population of roughly 1 million residents. Makhachkala is the fourth-largest city in the Caucasus, the largest city in the North Caucasus and the North Caucasian Federal District, as well as the third-largest city on the Caspian Sea, after Baku and Rasht. The city is extremely ethnically diverse, with a minor ethnic Russian population.

The city's historic predecessor is the port town of Anji (Andzhi), which was located in Kumykia, and which was a part of the possessions of the Tarki state, the capital of Kumyks known from the 8th century.

The Persian expedition of Catherine the Great of 1796, like the Persian expedition of Peter the Great (1722–1723), was one of the Russo-Persian Wars of the 18th century which did not entail any lasting consequences for either belligerent.

The last decades of the 18th century were marked by continual strife between rival claimants to the Peacock Throne. Empress Catherine the Great of Russia (r. 1762–1796) took advantage of the disorder to consolidate her control over the weak polities of the Caucasus, which was, for swaths of it, an integral Persian domain. The kingdom of Georgia, a subject of the Persians for many centuries, became a Russian protectorate in 1783, when King Erekle II signed the Treaty of Georgievsk, whereby the Empress promised to defend him in the case of Iranian attack. The shamkhals of Tarki followed this lead and accepted Russian protection three years later.

Shamkhal, or Shawhal (Kumyk: Şawxal) is a title used by Kumyk rulers in Dagestan and the Northeast Caucasus during the 8th–19th centuries. By the 16th century, the state had its capital at Tarki and was thus known as the Shamkhalate of Tarki.
