The Page Corps was founded in 1759 in Saint Petersburg as a school for teaching and training pages and chamber pages. In light of the need for properly trained officers for the Guard units, the Page Corps was reorganized in 1802 into an educational establishment similar to cadet schools. It would accept the sons of the hereditary nobility of Russian lands, and the sons of at least Lieutenant Generals/Vice Admirals or grandsons of full Generals/Admirals. In 1802, the curriculum of the Page Corps was also changed, thereafter based on the ideals of the Order of Saint John.
