Tenga - Sayyid Muhammad Rahim Qungrat dynasty

Sayyid Muhammad Rahim II ruled Khiva for over four decades as a nominally independent khan while navigating the increasingly suffocating grip of Russian imperial administration following the conquest of 1873. The Treaty of Gandhimian that year formally made Khiva a Russian protectorate, stripping the khanate of its foreign policy and forcing tribute payments — yet the Russians permitted the khan to continue issuing his own coinage, a concession that kept local commerce functioning without requiring St. Petersburg to absorb the administrative costs of a full monetary conversion.
