East Slavs, Volga Finnic, Tatar tribes inhabited the area and merged into an ethnos, a process virtually completed by the 13th century CE.

Later the Ryazan area became part of the Kievan Rus' political system and came under the domination of the Principality of Chernigov (founded in 988).

The Principality of Ryazan operated as a separate entity from 1097 to 1521, when the area became part of the Grand Duchy of Moscow, though with the Qasim Khanate district retaining some autonomy until the 1550s.

Because of series of misjudgement and overestimations these plans resulted in disastrous failure which is known today as Ryazan miracle (Russian: Рязанское чудо).
