The Pendleton Act established the Civil Service Commission.

Explanation:

Pendleton's Act for State Officers is a federal law in the United States passed in 1883, that prohibited the employment or dismissal of US federal officials on political grounds through the creation of the Civil Service Commission. Before the law came into force, it was normal for the ruling party to place party supporters in prominent positions.

For the first time, Rutherford B. Hayes, the Republican president from 1877 to 1881, tried to prevent political appointments. Hayes dismissed several politically appointed officials. Hayes's successor, Republican James Garfield, also actively sought to end political nominations. Garfield's plans fell short when he was shot early in the presidency. A few months later, after the death of Garfield, Vice President Chester A. Arthur became President. Before becoming president, Arthur supported political appointments, but unexpectedly supported Pendleton's Act, which he approved in January 1883.
