I think that this man deserved a thread, since he was the power behind the throne of Anna Ivanovna and, for three weeks, the regent of little tsar Ivan VI.

Ernst Johann von Bühren, also named Ernst Johann von Biren and Ernst Johann Biron, was only the grandson of a groom in the service of Jakob Kettler, Duke of Courland. His parents sent him to the academy of Königsberg, but he acquired a poor education, due to the fact that he was expelled from the academy for riotous conduct. So he tried to placed himself at the court of Sophie Charlotte, wife of the ill-fated tsarevich Alexis, son of Peter the Great; but he has not success in Russia and, later, he returned to Mittau, where was reigning Anna Ivanovna as widow of duke Friedrich Wilhelm. Biron became the lover of Anna...and this made his fortune!.
When Anna became empress of Russia, Biron became her grand-chamberlain. For years and years, Biron was the most powerful figure at San Petersburg´s court. The magnificence of his apartments adjoined those of the empress atonished everyone. I think, but I´m not sure, that his wife, Benigna, was placed in the service of Elisabeth Petrovna to guarantee that the daughter of Peter could not revolt against her cousin Anna Ivanovna.
The downfall of Ernst Johann and Benigna happened three weaks after the death of Anna Ivanovna. The couple and their three children were sending to Siberia, for an exile that ended twenty years later, during the reign of Peter III and Catherine II. Catherine II allowed Ernst Johann return to Mittau as Duke of Courland.
