The article is devoted to the scientific activity of Tamara Alexandrovna Khlebnikova (1928–2001), Candidate of Historical Sciences, a renowned expert in the field of Bulgar archaeology, who had played an important role in the study of the medieval Juketau city (the 10^th to the 14^th cc.) on the Lower Kama conducted in the 1960–1970s. In the 1960s, T. A. Khlebnikova initiated exploratory studies of the fortified settlement site, and in 1970–1972 supervised the first scientific excavations on this site. The results made it possible to characterize the main stages in the city’s existence from its formation to destruction. Stratigraphically, two levels were identified: the pre-Mongol one dated to the second half of the 10^th – first third of the 13^th century (1236), and the Golden Horde level (second third of the 13^th to the late 14^th or early 15^th cc.). It should be noted that the materials referring to the pre-Mongol time prevailed, which permitted to correct the views of Juketau being an exclusively Golden Horde city. In the 1990s, the studies of the Juketau fortified site have been resumed, supervised by F. Sh. Khuzin and N. G. Nabiullin, and basically confirmed the findings of T. A. Khlebnikova.
