The Federal Bureau of Intelligence is a US government organisation.

Founded in 1909, it has grown in size rapidly, and in 1969 became the only US intelligence service.

The bureau employs nearly 100,000 people, although it is limited to only 40,000 agents and 1000 special agents.

In 1974 the Central Information Agency was set up, to conduct background research and handle all declassified information.


The Bureau was set up in 1909 at the request of President Theodore Roosevelt. Its purpose was to gather information on foreign powers, and prevent foreign intervention on the American continent.
