Sergiyevsk

Sergiyevsk began as a fortified town in 1703 on the southeastern frontier of the Russian state. In the 1720s it was incorporated into the Second Trans-Kama defensive line, linking it to a wider system of forts across the region. Its administrative allegiance changed several times in the eighteenth century, between Kazan, Astrakhan and Orenburg governorates. In 1780 it received the status of an uyezd town in the Ufa Viceroyalty, giving the former fortress a civil administrative role.
