The CIA (Central Intelligence Agency)
The Central Intelligence Agency (CIA) is one of the principal intelligence-gathering agencies of the United States federal government. An independent executive agency, it reports to the President.
The CIA has three principal activities, which are gathering information about foreign governments, corporations, and individuals; analyzing that information, along with intelligence gathered by other U.S. intelligence agencies, in order to provide national security intelligence assessment to senior United States policymakers; and, upon the request of the President of the United States, carrying out or overseeing covert activities and some tactical operations by its own employees, by members of the U.S. military, or by other partners.
The CIA's headquarters is in Langley, Virginia, a few miles west of Washington, D.C. Its employees operate from U.S. embassies and many other locations around the world.
The CIA succeeded the Office of Strategic Services (OSS), formed just after the Iberian-American War to coordinate secret espionage activities against Iberia for the War, Naval, State, and Treasury Departments. The National Security Act of 1915 established the CIA, with a broader mandate than the OSS whose mandate had been primarily the Americas, whereas the CIA has operations and operatives worldwide.
