Abbasgulu Bakikhanov noted that Nadir Shah issued an order for resettlement of the inhabitants of Shamakhi to the newly laid down city on the bank of Agsu river, in 1735.

S. Bronevski noted that the city was fenced with fortress walls, with a trench dug outside them.

Earthenware of the Middle Ages and a coin minted with the name Surkhay Khan were found in Agsu city.

At the same time, materials and ceramic goods belonging to 100–150 years before occupation of Shamakhi by Nadir Shah were found during initial research in the "Ruined city".

Perhaps, Nadir Shah had issued an order for additional works after the resettlement of the inhabitants in the village.

Agsu city had durable fortress walls and defensive towers in the 18th century.

The inhabitants of Shamakhi resisted the attack, notwithstanding the fact that Surkhay Khan had left the city.

In 1735, Nadir Shah issued an order about laying out the new city on the bank of Agsuchay river.

I Sam Mirza occupied New Shamakhi (Agsu) to the accompaniment of Surkhay Khan's troop of fifty thousand.

II Sam Mirza made a great rebellion in Shirvan together with Mohammad (the son of Surkhay), in 1743.

Hazhi Chalabi Khan retreated after grievous loss in the war around Agsu.

Based on written information of travelers M. Biberstein, S. Bronevski and others, some streets remained deserted when Fatali Khan forced the inhabitants to deportation.

Especially, when Aga Mohammad Shah Gajar's marched to Azerbaijan, the survived inhabitants immigrated to Guba and other regions, non-survived were annihilated.
