Empress Anna Ioannovna, who reigned from 1730
to 1740, appointed her German “favorite,” Ernst-Ioann
Biron, the Duke of Courland and made him her closest adviser.
Thus, her decade in power came to be known as the Bironovshchina,
or the time of Biron. The man was cruel and tyrannical, and
many contemporaries and scholars regard this epoch as a reign
of terror. Suspected enemies among high-ranking officials were
imprisoned and executed, and 20,000 people were exiled to Siberia.
Before Anna died, she appointed Biron the regent for her great-nephew,
Ivan VI (r. 1740–41), but because of the hatred he had
earned, he was ousted from power after a mere twenty-two days
and then made his own long trek to Siberia.
