Mikhail Bestuzhev-Ryumin was born in the village Kudryoshky (Кудрёшки) of Gorbatovsky Uyezd, Nizhny Novgorod Governorate (guberniya) on June 4, 1801 (according to other sources 1803).
His father was the Mayor (городничий) of the town of Gorbatov, owner of 640 serfs and a muslin factory.
Bestuzhev-Ryumin was the most extreme republican among the Decembrists; he insisted on the need to execute the Emperor and his entire family.
On December 27, 1825 Mikhail was an assistant to Sergey Muravyov-Apostol, who headed the uprising of the Chernigov regiment.
He was executed at the Peter and Paul Fortress on July 25, 1826 and interred with the rest of the five in a secret grave on Goloday Island in Saint Petersburg.
