When was the CIA started?

July 26th, 1947 is the official date the CIA was created.

President Truman signs the National Security Act of 1947, creating the Central Intelligence Agency and National Security Council. The CIA is accountable to the president through the NSC -there is no democratic or congressional oversight. Its charter allows the CIA to "perform such other functions and duties as the National Security Council may from time to time direct." This loophole opens the door to covert action and dirty tricks.
