Vladimir Sergeyevich Salavyov (Russian: Влади́мир Серге́евич Соловьёв; January 28 [O.S. January 16] 1853 – August 13 [O.S. July 31] 1900) was a Russian philosopher, theologian, poet, pamphleteer and literary critic, who played a significant role in the development of Russian philosophy and poetry at the end of the 19th century and in the spiritual renaissance of the early 20th century.

Vladimir Sergeyevich Solovyov was born in Moscow on 16 January 1853, in the family of the historian Sergey Mikhaylovich Solovyov (1820–1879). His mother, Polyxena Vladimirovna, belonged to a Ukrainian-Polish family, having among her ancestors the thinker Hryhori Skovoroda (1722–1794).

In his teens Solovyov renounced Orthodox Christianity for nihilism, but later he changed his convictions and began expressing views in line again with the Orthodox Church. What prompted this change was his disapproval of Positivism. In his The Crisis of Western Philosophy: Against the Positivists he attempted to discredit the Positivists' rejection of Aristotle's essentialism or philosophical realism. In Against the Postivists he took the position of intuitive noetic comprehension, noesis or insight stating consciousness, in being is integral (Russian term being sobornost) and has to have both phenomenon (validated by dianonia) and noumenon validated intuitively? Positivism, according to Solovyov, only validates the phenomenon of an object, denying the intuitive reality which people experience as part of their consciousness.

Vladimir (Russian: Влади́мир; IPA: [vlɐˈdʲimʲɪr]) is a city and the administrative center of Vladimir Oblast, Russia, located on the Klyazma River, 200 kilometers (120 mi) to the east of Moscow along the M7 motorway. Population: 345,598 (2010 Census preliminary results); 315,954 (2002 Census); 349,702 (1989 Census).

Vladimir was one of the medieval capitals of Russia, and two of its cathedrals are a World Heritage Site. It is served by the Semyazino Airport, and during the Cold War Vladimir was host to Dobrynskoye air base.

The area occupied by the city of Vladimir has been inhabited by humans (at least intermittently) for approximately 25,000 years (see Sungir). Traditionally, the founding date of Vladimir has been acknowledged as 1108, as the first mention of Vladimir in the Primary Chronicle appears under that year. This view attributes the founding of the city, and its name, to Vladimir Monomakh, who inherited the region as part of the Rostov-Suzdal Principality in 1093. In 1958, the 850th anniversary of the city foundation was celebrated, with many monuments from the celebrations adorning the city squares.

Mikhail Ryabko (born May 6, 1961) is a Colonel in the Russian military, serves as a Special Advisor to the Minister of Justice of the Russian Federation (currently Alexandr Konovalov) and is the founder of Ryabko's Systema.

His martial training was started at the age of five, by a member of Joseph Stalin's personal bodyguards with traditional Russian martial arts training. At 15 he was enlisted to the ranks of Spetsnaz (Russian special forces) and has served since.

He is active as a martial trainer and advisor and is the author of several publications as well as a textbook on the tactics of Special Operations.

His senior student is Vladimir Vasiliev whose school in Thornhill, Ontario Canada is considered the Systema headquarters outside of Russia, as is evidenced by the website http://russianmartialart.com working as a sort of "hub" gathering data concerning many schools worldwide, schools whose lead instructors have almost always had their Instructor credentials either certified by V. Vasiliev or M.Ryabko, sometimes given by Instructors associated with Vasiliev, such as S. Puzikas and K. Komarov.
