Irkutsk Kazachinskoye

Kazachinskoye is a village on the Kirenga, a tributary of the Lena. The regional library's historical calendar dates its foundation to 1776. It places the village within a longer sequence of settlement along the Kirenga, where Russian travelers had appeared in 1636–1638 and where Semyon Remezov's drawing book later showed eight unnamed villages.

The valley also became associated with exiled Cossacks, a connection remembered in local settlement names. A commemorative village history preserves a more specific early nineteenth-century record: in 1822 an order encouraging grain cultivation and potato growing reached the Kirensk district and the village then called Kazarki. Such an instruction shows provincial government addressing the food production of a small river community.
