Empress Anna died soon thereafter on 28 October 1740. The following day the infant was proclaimed emperor as Ivan VI, Autocrat of All The Russias, and Biron became regent. However, the idea of Biron wielding power was not acceptable either to Ivan's parents or to most of the nobility. During his years as Anna's lover he had made many enemies, and was tremendously unpopular at court. Within three weeks Ivan's father had engineered Biron's fall. At midnight on 18/19 November 1740 Biron was seized in his bedroom by partisans of the royal couple and banished to Siberia (he was later permitted to reside at Yaroslavl). Ivan's mother, Anna Leopoldovna, was made regent, though the vice-chancellor, Andrei Osterman, effectively ran the government during her brief regency.
