Answer:
The Pendleton Act established the United States Civil Service Commission.
Explanation:
The Pendleton Civil Service Reform Act, adopted in 1883, prohibited the recruitment or removal of US federal officials on political grounds. Before the law came into force, it was normal for the ruling party to place party supporters in significant posts.
This law also created the Civil Service Commission, a government agency, whose original purpose was to assess the performance of employees within the federal government. The Civil Service Reform Act of 1978 caused it to be dissolved in 1979.
