The Cadet Corps (in Russian: Kadetskiy Korpus, Кадетский Корпус) is an admissions-based all boys military academy which prepared boys to become commissioned officers. Boys between the ages of 8 and 15 were enrolled. It was founded in Saint Petersburg, Russian Empire in 1731 by Empress Anna. The term of education was seven years. All instructors had a military rank, and taught a full program of military preparation. In 1766 Catherine the Great's educational reforms broadened the curriculum to include the sciences, philosophy, ethics, history, and international law.
