Idrinskoye
Idrinskoye developed in the southern Siberian country of the Syda and Idra rivers. Tradition says Cossacks founded the village in 1736, and it appears in a 1779 confession register of the Resurrection Church in the Abakan district. The settlement appears under several related spellings, including Idrinskaya, Idra and Idrinskoye.
With the creation of Yenisei province, the village acquired a new administrative role: in 1823 it became the centre of a volost within Minusinsk district. Idrinskoye thus entered the growing civil administration of southern Siberia, after its early ties to the Cossack settlements around Abakan.
