In 1733, due to concerns about the expansion of the Ottoman Turks in the region, the Feappii tried to establish ties with the Kingdom of Kartli.

[2][3][4][5] Foma Gorepekin [ru] translated the ethnonym in Ingush language as "settlers marching in a discordant crowd".

[6] Similarly, Rusudan Kharadze and Aleksey Robakidze made a hypothesis that the ethnonym might be connected with the term "alien/new settler" (but not as ethnically different from the main mass of Ingush).

[10] Eventually, the meaning of this ethnonym expanded to cover all Nakh peoples, despite originally referring specifically to the Feappii.

[c] The first recorded mention of Kists dates back to the 7th century, in the work Ashkharhatsuyts, where it appeared in the form Kusts.

Tyarsh is the name of their eldest father.In 1733, fearing the expansion of the Ottoman Turks, the Fyappins and Dzherakh wrote a letter to Vakhtang VI, declaring their oath of allegiance to Kartli.

[e][29] However, it's essential to note that despite these oaths from individual Ingush societies or clans, the nature of Russian-Ingush relations remained largely unchanged.

In July 1830, two Russian columns led by Major General Abkhazov embarked on a punitive expedition to mountainous Ingushetia.

The Russian forces traversed the Darial and Assa Gorges, encountering fierce resistance, particularly from the inhabitants of Eban.

[46][g] In 1989, Kodzoev, along with other Fyappin representatives like Sulambek Mamilov, was part of the committee for the revival of Ingush autonomy within the Russian SFSR of the Soviet Union.

[48] Fyappin society consisted of the following fortified villages (auls), tribal organizations (teips), and surnames (nyaqhash/vyarash):[i] Didigovs (Дидигнаькъан) Patievs (Патнаькъан) Mizievs (Мизинаькъан) Gumukovs (Гумукнаькъан) Torievs (Торинаькъан) Amerhanovs (Амерхананаькъан) Kotiyevs (Котнаькъан), Kusievs (Кусенаькъан), Tochiyevs (Тоачанаькъан) Dzortovs (Дзортонаькъан), Yaryzhevs (Ярыжнаькъан), Ortskhanovs (Орцхонаькъан), Bagaevs (Баганаькъан)
