In March 1917 at the age of 27, he was promoted to frigate captain, before being appointed Principal Private Secretary to Alexander Kerensky in the first provisional government, led by Prince Georgy Lvov.
Following this he was appointed deputy chief of staff of the Black Sea fleet by Kerensky, who in turn became head of the Russian government until his overthrow by the Bolsheviks during the October Revolution of 1917.
Shortly after the signing of Treaty of Brest-Litovsk in 1918, he left the military but remained in Crimea to devote himself to business interests, archaeological work as well as esoteric and historical research.
From his youth, Mouravieff was interested in the esoteric tradition of the Eastern Orthodox Church, helped by indications left by Andreï Mouraviov (A.N.
Mouravieff), his great-uncle (who died in 1874) and a founder of the Skete of Saint Andrew, one of the great Orthodox monasteries of Mount Athos.
The latter had undertaken research in Egypt, Armenia, Kurdistan and even Persia to find traces of this tradition and manuscripts from the first centuries of our Common Era.
While in Constantinople between 1920 and 1921 Mouravieff attended public lectures given by P. D. Ouspensky and became acquainted with Gurdjieff, with whom he had contact in later years, both at Fontainebleau and in Paris.
Mouravieff and Ouspensky became close friends and worked together either in Paris or London for many years most notably on the manuscript of In Search of the Miraculous.
Up until 1941, Mouravieff worked as a consulting engineer for various oil companies, while devoting his free time to historical research, as well as to the esoteric tradition of Eastern Orthodoxy.
Since 1921, Mouravieff had pursued his research into the political and diplomatic history of Russia, and in particular to Peter the Great, which gave rise to a number of articles and books.
[8][9] Fearing further arrest resistance fighters of the local French Gendarmerie organised his and his family's escape on March 9, 1944, for Switzerland.
At the end of the war, they were allowed to settle in Geneva and stayed at an establishment called "Home for Intellectual Refugees", while waiting for an apartment in town.
General questions were answered through a series of writings entitled "A collection of notes on esoteric Christian teaching: The Stromata", in imitation of Clement of Alexandria.
With these Stromates, grouped under the general title of "The Art of Winning", Boris Mouravieff embarked on a vast and ambitious project.
Mouravieff's widow Larissa published chapters 2 and 3 of the first "Stromate" in 1968 and 1970 and maintained the archives of the centre until 1988, when she emigrated to join her son Boris Vsevolod Volkoff in Canada.
When the latter died, in March 2012, the remaining archives were handed over to the Library of Geneva (BGE, department of manuscripts), where a Mouravieff collection had been set up.
