Gregory Rasputin figures in Russian history as a malign and destructive force, a man with an unhealthy influence on the Empress Alexandra and undue power in Russian politics. Yet, his purposes were obstensibly beneficient. An uneducated peasant, he left Siberia to become a wandering "holy man" and soon acquired a reputation as a healer. The empress was desperate to find a cure for the haemophilia from which her son Alexei suffered, and in 1905 Rasputin was presented at court. His positive effect on the heir's health made him indispensable. But his religious teachings were unorthodox, and his charismatic presence aroused in many ladies of the St Petersburg aristocracy an exalted response, which he exploited sexually. Shady financial dealings added to the atmosphere of debauchery and scandal, and he was also seen as a political threat. He was assassinated in 1916.
