After the Russian defeat in the Crimean War during the reign of Alexander II, the Minister of War Dmitry Milyutin introduced military reforms, with an initial draft presented in 1862. On January 1, 1874 , a statute concerning conscription was approved by the Tsar by which military service was made compulsory for all males at the age of 21. The term of actual service was reduced for the land army to 6 years followed by 9 years in the reserve. This measure created a large pool of military reservists ready to be mobilized in the event of war, while permitting the maintenance of a smaller active army during peacetime. Most naval conscripts had an obligation for 7 years service, reflecting the more extended period required for technical training.
