Tadqiqotchilarning fikricha, qadimgi Farg'onada shaharlashuv va davlatchilikning rivojlanishi, Markaziy Osiyoning rivojlangan tarixiy-madaniy mintaqalari (Xorazm, Baktriya, Sug'd va Parfienna) bilan solishtirganda, ularda shaharlar miloddan avvalgi VIII–VII asrlarda paydo bo'lgan, ancha kechikib sodir bo'lgan. Ularning fikricha, bu kechikishga uning tog'tizmalari bilan o'ralgan, rivojlangan hududlardan ajralib turadigan provintsial, chekka joylashuvi sabab bo'lgan. Qadimgi shaharga xos bo'lgan Ark-tsitadel, Shahriston (mudofaa devorlari bilan himoyalangan shahar kvartallari) va rabod (shaharning mustahkamlanmagan qismi) kabi elementlar, tuzilmalar va topografiyani aks ettiruvchi eng qadimgi belgilar Farg'ona vodiysida arxeologlarning Eylatan va eski Ahsi shaharlaridagi tadqiqotlari tufayli ma'lum bo'lgan. Ularning eng qadimgi arxeologik majmualari miloddan avvalgi III asrdan erta bo'lmagan davrga tegishli. Biroq, so'nggi o'n yillikda olib borilgan arxeologik tadqiqotlar – 2012 yilda biz tomonimizdan qirq-hujra noyob shahar xarobalarining ochilishi tufayli – Farg'ona vodiysida miloddan avvalgi VII-VI asrlardayoq, markazlashgan davlat sharoitidagina mavjud bo'lishi mumkin bo'lgan shaharga xos rivojlangan elementlarga ega yuqori darajada urbanizasiyalashgan madaniyat mavjud bo'lganligini ko'rsatuvchi materiallar olindi.

According to researchers, the development of urbanization and statehood in ancient Fergana occurred with significant delay compared to the developed historical and cultural regions of Central Asia (Khorezm, Bactria, Sogdiana, and Parthienna), where cities emerged in the 8th-7th centuries BCE. The reason for this delay, in their opinion, was its provincial, peripheral location, isolated from developed areas by mountain ranges. The earliest signs illustrating elements, structures, and topography characteristic of an ancient city – the ark-citadel, shahristan (urban quarters protected by defensive walls), and rabat (unfortified part of the city) – were known in the Fergana Valley thanks to archaeological research at the sites of Eylatan and Eski Akhsy. Their earliest archaeological complexes date back no earlier than the 3rd century BCE. However, thanks to archaeological research conducted in the last decade – including our discovery of the unique settlement of Kyrk-Khujra in 2012 – materials have been obtained indicating that a highly urbanized culture with developed urban characteristics existed in the Fergana Valley at least as early as the 7th century BCE. The existence of such a culture is only possible under conditions of a centralized state.
