The Central Intelligence Agency (CIA): History, Intelligence, and Global Influence (1947–Present)

Introduction

The Central Intelligence Agency (CIA) is the primary foreign intelligence agency of the United States. Its main responsibilities include:

Collecting foreign intelligence.

Analyzing political, military, economic, and scientific information.

Conducting covert operations when authorized by the U.S. government.

Supporting U.S. national security and foreign policy.

Unlike domestic law enforcement agencies, the CIA generally focuses on intelligence activities outside the United States.

Why Was the CIA Created?

During World War II, the United States relied on the Office of Strategic Services (OSS) for espionage and special operations.

After the war, U.S. leaders concluded that a permanent intelligence agency was needed because of growing tensions with the Soviet Union.

The National Security Act of 1947 established the CIA on 18 September 1947.
