The article is devoted to the analysis of pottery traditions of the population associated with the existence of “long houses” on Staraya-Maina hillfort (Ulyanovsk Oblast), dated by the Great Migration Period. The research is based on the ceramic collection found on the hillfort during the excavations in 1990–1991. This paper presents a typological description of vessels and the results of technological analysis conducted by the author according to A. A. Bobrinsky’s method. The analysis revealed two massive pottery traditions, one of which was widely known on Imenkovo culture settlements, while the second one was a new discovery. The author suggests that this group of ceramics might be associated with an inflow of population from the Middle Oka region and from the Oka-Sura region in the fifth century AD, which brought the typical complex of garnishments of Ryazan-Oka type to the Middle Volga region.
