In the 1700s, Kazan Tatar (Muslim scholars of Kazan) and scholarly networks stood at the forefront of Russia's expansion into the South Urals, western Siberia, and the Kazakh steppe. It was there that the Tatars worked with Russian agents, established settlements, and spread their own religious and intellectual cuture that helped shaped their identity in the nineteenth and early twentieth centuries. Kazan Tatars profited economically from Russia's commercial and military expansion to Muslim lands and began to present themselves as leaders capable of bringing Islamic modernity to the rest of Russia's Muslim population.
