One of the oldest federal agencies, the Federal Bureau of Investigations has evolved over the last hundred years to become the Department of Justice's main law enforcement agency. This book explores its history, agents, law enforcement reach, and role as part of the American intelligence community, as well as the public storms weathered by the Bureau. Students will learn about the FBI's earliest days in the late 1890s to the wild years of J. Edgar Hoover to the recent role of the FBI in our political discourse.
