Background:
The series "Union of Salvation" is a sweeping historical drama based on real events that chronicles the development of the Decembrist movement in Russia in the early 19th century. The action unfolds from 1814 to 1826—from the triumphant return of the Russian army from its foreign campaign after defeating Napoleon to the suppression of the Senate Square uprising and the execution of its leaders.
After victory in the Patriotic War of 1812 and the campaigns in Europe, many young officers who had fought in the war witnessed free states with parliaments and constitutions. Returning home, they were shocked by the persistence of serfdom, despotism, and brutal military discipline. These contradictions sparked a desire for change.
The series shows how a group of young members of the military elite—such as Pavel Pestel, Sergei Trubetskoy, Kondraty Ryleyev, Mikhail Bestuzhev-Ryumin, and others—unite to form a secret society called the "Union of Salvation."

December 14, 1825, St. Petersburg Square. Enraged soldiers and officers came out onto the square and formed a huge line. There were a huge crowd, and Trubetskoy and Muravyov were in charge, but Trubetskoy rejected the idea and simply didn't show up. Muravyov, as the regiment's senior officer, was preparing the soldiers for the attack on Nicholas I. Bestuzhev stood nearby and looked on at the entire army.

Bestuzhev: - Yeah, Sergei... I didn't think we'd get to this point... I thought they'd killed us a long time ago. - Pestel immediately looked at Bestuzhev and made a dissatisfied face.
Pestel: - Quiet! You are setting MY regiment against us, and I don’t need that, Mr. Bestuzhev.
