Nikolai Yudenich was the most consistently victorious Russian field commander of World War I, destroying the Ottoman Third Army through the battles of Sarikamish, Erzurum, and Trebizond on the Caucasus Front.

The Empire's legal architect who tamed the Duma with the "shameless" electoral law of 1907

As Assistant Minister of the Interior, he drafted three versions of the 1907 electoral law and himself called the adopted one "shameless": it guaranteed seats to worker and peasant curiae but let the landowner-dominated provincial assemblies pick the actual deputies from their electors. He served as the last State Secretary of the Empire from 1911 until its collapse, and after the revolution emigrated to Paris, where he edited a monarchist memoir journal until the end of his life.

Well-read in revolutionary theory, he argued that repression alone could not defeat revolution and devised 'police socialism': pro-government legal trade unions that channeled workers' economic grievances away from political agitation. His experiment collapsed in the 1903 Odessa general strike and he was dismissed by Plehve, but his vision of preserving autocracy through social reform remains the most original attempt by the old regime to confront the labor question before 1905.

From Legal Marxism to ethical socialism: the economist who pioneered business cycle theory

At the April 1900 Pskov meeting to organize Iskra, he sat alongside Lenin, Martov, and Struve — but he never actually joined the underground Social Democratic movement.

A leading exponent of Legal Marxism, Tugan-Baranovsky gained international recognition with his 1894 Industrial Crises in Contemporary England, which pioneered an endogenous theory of capitalist business cycles. Together with Pyotr Struve he advanced Marxist economic-historical analysis against the Narodniks and attended the 1900 organizational meeting of Iskra, but later broke with orthodox Marxism toward an 'ethical socialism' grounded in Kantian ethics, laying the theoretical foundations of the cooperative movement. After the February Revolution he served as finance minister in the Ukrainian Central Rada and was a founding member of the Ukrainian Academy of Sciences; his cycle theory influenced Keynes, Robertson, and Kalecki.

The patriarch who led the Russian Church through revolution

During the 1922 dispute over church valuables, he distinguished voluntary gifts for the starving from the compulsory seizure of sacred objects.

Tikhon was a Russian Orthodox hierarch and the first holder of the patriarchate restored in 1917, becoming the central figure in the Church’s confrontation with the post-revolutionary state. During the famine of 1921–1922 he appealed for relief, but after the February 1922 decree he distinguished voluntary donations from the compulsory surrender of sacred objects, which he regarded as a violation of canon law. His position defended ecclesiastical autonomy, yet it could not prevent a confrontation that brought prosecutions, executions of clergy, and the seizure of church property.
