Widespread public demand for civil service reform was stirred after the Civil War by mounting incompetence, graft, corruption, and theft in federal departments and agencies. After Pres. James A. Garfield was assassinated in 1881 by a disappointed office seeker, civil service reform became a leading issue in the midterm elections of 1882. In January 1883, Congress passed a comprehensive civil service bill sponsored by Sen. George H. Pendleton of Ohio, providing for the open selection of government employees—to be administered by a Civil Service Commission—and guaranteeing the right of citizens to compete for federal appointment without regard to politics, religion, race, or national origin. Only about 10 percent of the positions in the federal government were covered by the new law, but nearly every president after Chester A. Arthur, who signed the bill into law, broadened its scope. By 1980 more than 90 percent of federal employees were protected by the act.
