The Birth of the Bureau: FBI Founded

What Happened?
When the Department of Justice was created in 1870, it had no investigative team. That changed on July 26, 1908, when Attorney General Charles Bonaparte assembled a new squad of federal agents. One year later, it was renamed the Bureau of Investigation, and by 1935, it became the FBI.
Under J. Edgar Hoover, who took control in 1924, the FBI exploded in size and influence. He professionalized federal policing with tools like fingerprint databases, crime labs, and intensive agent training. Hoover also turned the bureau into a national propaganda machine. The media loved the 'G-Men', especially when they gunned down gangsters like John Dillinger and 'Machine Gun' Kelly during Prohibition.
But behind the headlines, the bureau developed a dark side. Hoover launched domestic surveillance operations against anyone he deemed a threat, from civil rights leaders like Martin Luther King Jr. to leftist organizers, Native activists, and anti-war protesters. Through COINTELPRO, the FBI infiltrated, discredited, and disrupted legal organizations, violating constitutional rights in the name of national security.
By the late 1960s, critics across the political spectrum began to question the unchecked power of Hoover’s FBI. After his death in 1972 and the fallout from the Watergate scandal, Congress finally placed limits on the bureau’s reach. Still, new scandals emerged—from protecting corrupt presidents to surveilling Black Lives Matter activists in the 21st century.
Today, the FBI sits at the intersection of democracy and secrecy. It investigates hate crimes and public corruption, but also faces scrutiny for overreach, political bias, and abuses of surveillance power. With over 56 field offices and agents around the globe, the bureau remains one of the most powerful and polarizing arms of the U.S. government.
Why It Matters
The FBI began as a modest investigative unit. It became a mirror of American power: efficient, ambitious, and often conflicted. Its rise is a cautionary tale about what happens when law enforcement gains influence without equal accountability. Understanding the FBI’s legacy means asking hard questions about justice, civil liberties, and who decides what counts as 'dangerous.'
