When did the United States create a professional federal civil service?

The United States established a professional federal civil service with the passage of the Pendleton Civil Service Act on January 16, 1883.1

Prior to this legislation, the federal government largely operated under the spoils system, a practice where government positions were awarded based on political party affiliation rather than professional qualifications. This system often led to inefficiency, corruption, and incompetence within federal agencies.12

Public demand for reform intensified following the assassination of President James A. Garfield in 1881 by a disgruntled office seeker. In response, Congress passed the act sponsored by Senator George Pendleton, which introduced a merit-based system for federal employment. The law established a Civil Service Commission to oversee the open selection of employees through competitive examinations, ensuring that appointments were based on ability rather than political patronage. While the act initially covered only about 10 percent of federal positions, its scope was steadily expanded by subsequent administrations.13
