Tuma
Tuma lies in the forests of Meshchera, between the Oka and Klyazma river systems. First recorded in 1518 as a Finnic village, it stood on a road linking Pereyaslavl-Ryazansky with Vladimir and Kasimov. The surrounding woods and wetlands gave the district a character distinct from the open farmland to the south. In 1778 the Tuma district was assigned to Kasimov as part of the reorganization of Ryazan's provincial administration.
