The United States Secret Service (USSS) has a long and multifaceted history that spans over 150 years, marked by its evolution from a financial crimes agency to one of the most recognizable protective services in the world.

Origins and Early Mission

The Secret Service was established on July 5, 1865, under the Department of the Treasury. Its primary mission was to combat the rampant counterfeiting that threatened to destabilize the post-Civil War economy. At that time, it was estimated that nearly one-third of all currency in circulation was counterfeit, posing a severe risk to the financial stability of the United States. Establishing the Secret Service was critical to restoring trust in the nation’s monetary system and ensuring economic stability.

Expansion into Protective Duties

The assassination of President William McKinley in 1901 was a pivotal moment for the Secret Service. This event, combined with the earlier assassinations of Presidents Abraham Lincoln and James Garfield, underscored the need for dedicated presidential protection. In 1902, the Secret Service was formally tasked with protecting the President of the United States. This new responsibility marked the beginning of the agency’s dual mission of protection and investigation.

Growth and Legislative Support

Over the years, Congress has enacted various pieces of legislation to enhance and expand the Secret Service’s protective mission. For example, the 1917 Espionage Act granted the Secret Service the authority to investigate espionage activities during World War I, expanding the agency’s role in national security beyond financial crimes.

In 1970, the Uniformed Division was created to provide security for the White House Complex and the Vice President’s residence. This division also took on the responsibility of protecting foreign embassies and consulates in Washington, D.C. The scope of the Secret Service’s protective duties continued to grow, with significant expansions following major national security events and presidential directives.
