Izberdey
Izberdey takes its name from the Izberdeyka River, which flows into the Matyra in the country west of Tambov. The river gave its name to more than one village, including Bolshoy and Maly Izberdey. Bolshoy Izberdey had grown into a substantial settlement by 1719. Earlier, the Matyra outpost founded in 1644 had formed part of the Tambov frontier line, built to guard the region against raids from the steppe.
