Before this state of things, there was a gradual division of opinion among Republicans at the North, and especially among their leaders. Against the call to protect the freedmen and bridle the slave-holding spirit in its new forms, rose the call to return to the old respect for local rights, and let each Southern State manage its own affairs, as did each Northern State. To this changed attitude came some of the staunchest of the old anti-slavery leaders, and many of the younger generation. During the early years of Grant's administration, the question did not present itself in acute forms. The Ku-Klux law of 1870, though it might strain the Constitution a little, received general acquiescence because the abuse it aimed at was so flagrant. But the ostracism of the entire official class of the old South was growingly recognized as a grievance and a wrong. It was the spirit of proscription that brought on the political crisis of 1872. That proscriptive spirit broke up the Republican party in Missouri; the liberal element, led by Carl Schurz and B. Gratz Brown, held a State convention. Their movement fell in with a strong rising tide of opposition to Grant's administration within the Republican party. Its grounds were various,--chiefly, a protest against wide and gross maladministration, a demand for a reformed and scientific civil-service, opposition to the high tariff, and the desire for a more generous and reconciling policy toward the South. The movement was especially prompted by a group of leading independent journals conducted by very able men,--the New York _Evening Post_, under William Cullen Bryant; the _Nation_, edited by E. L. Godkin; the Cincinnati _Commercial_ of Murat Halstead; the Louisville _Courier-Journal_ of Henry Watterson; the Springfield _Republican_ of Samuel Bowles. Sympathetic in the main was Horace Greeley's New York _Tribune_. In more or less close alliance were a few of the congressional leaders, notably Sumner, who had quarreled bitterly with Grant over the proposed annexation of San Domingo; Trumbull, who was never in close touch with his old party after the impeachment trial; and Carl Schurz, who was now in the Senate.
