From the 6th to the 15th centuries, the aul was the center of the independent region of Zirikhgeran, whose inhabitants were known as zirikhgeran (from the Persian word for chainmail makers). A dinar from Kubachi dates back to 815/816. Since the 15th century, the inhabitants have been known by the Turkic name Kubachi with the same meaning.

Around 1305, the villagers converted to Islam. On the eve of Islamization, Zirikhgeran apparently experienced a political crisis. According to legend, a split occurred among the inhabitants of the main settlement of Zirikhgeran, with a smaller group founding the village of Ashty. Soon, some of the zirikhgerans left the main settlement and founded the villages of Shiri and Sulevchi. The latter was established when the Kubachins decided to build mills by the river and set up households to maintain them. Researchers tend to date the construction of fortress walls with tower-forts around Zirikhgeran to this period, i.e., the 13th–14th centuries, remnants of which have survived to this day. According to Fanucci, the settlement of Kubachi was built and populated by Genoese. In the 18th century, academician Johann Anton Güldenstädt, in his description of his travels in the Caucasus, reported that descendants of the Genoese lived in Kubachi.

Kubachins-zirikhgerans smelted iron from ore in the area of Khyabkoyla Katala near the aul of Chumli, and then the metal was brought to Ugbug-Kubachi, where it was finally processed.

According to local legend, the Upper quarter of the village accepted Islam 7 years later than the Lower quarter. It is noted that the Islamization of Zirikhgeran was forced and carried out through a treaty.

Around 1467, the name Gubeshi was first mentioned, which in Turkic means "armorers, makers of armor." The local name of the village Kubachi is a significantly altered Turkic name over a long period: Gubeshi—Gyubeshi—Gyobeshi—Gyubezhi—Gubechi—Kyubechi—Kubachi. The Turkic name Gubeshi means "chainmail makers, chainmail smiths."

The early 18th-century traveler Lopukhin described Kubachi in his writings as follows: "From this city (Derbent), in the mountains about a day and a half's ride away, there is a city called Kubeshi, about which it is said that it is a great place to live and there is a stone wall around it. Especially, they say, the location is very strong. All the inhabitants are skilled craftsmen and traders, have no quarrels with anyone, listen to no one, live by themselves, and have rulers from among their own brothers. Their craft is such—they make many good small firearms, and, they say, also cast cannons. They have a considerable supply of wool, from which they make cloth themselves, and their craftsmanship is not bad. Their wool is good and soft; they buy it by the batman weight, which is 14 pounds, for the best at 20 altyns per batman, and sometimes less. That wool is comparable to Spanish wool, good. Such wool is not found anywhere better than theirs."

Regarding the Kubachins in the 18th century, the Russian statesman and historian Tatishchev stated: "Kubachi is a small people in Dagestan, but very famous for their works, such as firearms, cloth, burkas, gold, silver, and iron trinkets, and because of this, many counterfeit Persian, Turkish, and Russian gold and silver coins come from them."

Local women—Kubachinkas—still actively wear traditional clothing today—luxurious white veils (kazy), which are draped in an original manner. Another historical fact is connected precisely with the Kubachinkas. The well-known academician Fren in one of his works recounted the history of the aul: "Once a week, wives abandoned by their husbands and widows would sit on benches placed in front of their houses and give themselves to young men who remained forever unknown to them. This happened between 2 and 3 a.m. with their faces covered. Moreover, this was not considered shameful; on the contrary, the offspring of such relations were raised and subsequently fully supported at public expense."

Muchaly are another cultural attraction of the village. These are special water jugs shaped like cones with truncated ends and connected to each other. According to legend, once the Persian Shah Nadir besieged the village and in the evenings observed it through a spyglass. He offered the already besieged residents to surrender via a messenger. However, one resourceful local proposed a plan to repel the would-be conquerors: to place three muchaly on the roof of each house, which from afar resembled small cannons. The proposal was accepted, and in just one night, muchaly appeared on every roof. So one fine morning, Nadir-shah saw through his spyglass that weapons were aimed directly at him. The next night, on one of the roofs, a tar-soaked tow was deliberately set on fire. Frightened that the residents were starting a fight, the Persians feared an attack on their camp and fled."

Among the most famous works of the Kubachins are named the two-horned helmet of Alexander the Great, the shield of Alexander Nevsky, Nadir Shah’s saber, and a later relic—a set of cold weapons from the Victoria and Albert Museum in London, gifted by Tsar Alexander III to Queen Victoria. Kubachin sabers were used by the dragoons of the Russian Empire, who took pride not only in the combat qualities of the steel blade but also in the engraving and carving on the scabbards and handles.
