Espionage



Espionage, systematic secret gathering of information about the plans and activities of foreign governments or competing businesses. Espionage is as old as war itself, but modern military intelligence gathering developed under Frederick the Great of Prussia in the 18th century. Extensive espionage networks were developed during World War II, and since then intelligence agencies have become significant components of the state apparatus in many countries.
