'Cadet Corps' (in Russian: ''Kadetskiy Korpus, Кадетский Корпус'') is an admissions based military middle school for young boys that was founded in the
Russian Empire in the year 1732, soon becoming widespread throughout the country. The term of education was seven years. All instructors had a military rank, and taught a wide range of subjects, including a full program of military preparation.
A graduate from the corps became a
junker and had prime candidacy for a military career.
During the
October Revolution cadets and junkers overwhelmingly supported the
White movement. Consequently, the Bolshevik government dissolved all cadet corps.

Many cadets emigrated and formed cadet corps in other countries, most notably in the
Kingdom of Yugoslavia (
Bela Crkva), where they received the patronage of
Alexander I of Yugoslavia - himself a graduate from the St. Petersburg cadet corps.
During
World War II a number of
White emigre cadets joined the
Russian Corps, feeling it was a means of continuing the battle against the Bolshevik regime.
After
World War II, with the emigration of cadets to the
United States,
Canada,
Argentina, and
Australia, White emigre cadet corps ceased to function. A cadet union was formed to unite the graduates of the cadet corps.
After the fall of the
USSR, cadet corps became reestablished in Russia, and continue to grow.
