Union of Salvation

The Union of Salvation (Russian: "Союз спасения", or Soyuz spaseniya), also known as the Society of True and Loyal Sons of the Fatherland since 1817 ("Общество истинных и верных сынов отечества", or Obshchestvo istinnykh i vernykh synov otechestva) was the first secret political society of the Decembrists.

The Union of Salvation (UoS) was founded in 1816 at the initiative of Alexander Nikolayevich Muravyov by a group of young officers of the Russian army, who had taken part in the Patriotic War of 1812 and foreign campaigns of 1813–1814. UoS numbered some 30 members, including Nikita Muravyov, Sergey Muravyov-Apostol, Matvei Muravyov-Apostol, Sergei Trubetskoy, Ivan Yakushkin, Pavel Pestel, Yevgeni Obolensky, Ivan Pushchin, Mikhail Lunin and others. In 1817, they approved the UoS charter and changed the society's name to Society of True and Loyal Sons of the Fatherland. The UoS aimed at the abolishment of serfdom and introduction of constitutional monarchy by means of armed revolt at the time of next emperor's succession to the throne. While preparing for the seizure of power, the UoS members had to try and expand the society's influence, secure key military and civil posts in government structures, and form public opinion.

The UoS members were divided into three categories – bolyare (боляре), muzhi (мужи), and brat'ya (братья). The conspiracy was such that only the first two categories of members knew the final purpose of the society. Low-ranking members had to obey high-ranking members implicitly. The admission of new members, as well as internal promotion, could only take place with the consent of the supreme council of the bolyare. Initiations and promotions were accomplished in strict accordance with a complex system of rituals and vows, adopted from Freemasonry.
