Every President after Jackson used the offices for partisan purposes, and few objected to the practice on theoretical grounds. The simplicity of the National Government made the habit less destructive than it otherwise would have been. The spoils system did not enter the army or navy, the only extensive technical departments of the United States. In other branches of the Government a large majority of the officials were unskilled penmen, whose places could easily be filled with others as little skilled as themselves. Always a few clerks who knew the business were saved to guide the recruits, and the departments were generally working again before a President met his first Congress. Lincoln was not different from his predecessors in the use of offices. He permitted the most complete sweep that had yet been made, being forced to an unusually high percentage of new appointments by the necessity of removing Southerners. In his hands the patronage became an additional weapon for the Union, upholding the leaders in Congress, and striking at the backsliders. In the election of 1864 the Union party carried all the branches of the Government, and it had a vision of four years of complete control of the offices when the death of Lincoln brought a Tennessee Democrat into the White. House. The discussion of civil service reform, on theoretical grounds, began about 1865, when the evil of removals for party purposes was shown to the Senate. Johnson was trying to use the patronage for his own ends, in opposition to the will of the radicals in Congress. Reformers who maintained the iniquity of this custom now found temporary converts among the Republicans. They got a committee appointed on the civil service in 1866, and President Grant announced his conversion to the principle early in his Administration. In 1871 Congress tried the experiment of a modest appropriation ($25,000) for a reform of the civil service, and Grant placed the test in the hands of George William Curtis, a leader of the new reform. The commission breasted the whole current of politics, found that Grant would not support it in critical cases, and was abandoned by Congress after a short trial. The demand, however, increased, receiving the support of the independents who were Liberal Republicans in 1872, and who thereafter constituted a menace to party regularity. Schurz, Godkin, and Curtis were their admitted leaders. In 1872 and 1876 they persuaded the great parties to put general pledges for civil service reform into their platforms. Schurz, as Secretary of the Interior under Hayes, put their ideal partly into practice. In 1881 they were a well-recognized body of advocates, with a definite doctrine of non-partisan efficiency, which few politicians denied in principle or liked in fact.
