Thenceforward new alliances were rapidly formed. In the South those Whigs who, though still unwilling to profess an anti-slavery creed, would not unite with the Democrats, were re-organized under the name of the American party, with Humphrey Marshall, Henry Winter Davis, Horace Maynard, and men of that class, for leaders. This party was founded on proscription of foreigners, and with special hostility to the Roman-Catholic Church. It had a fitful and feverish success, and in 1845-5, under the name of _Know-Nothings_, enrolled tens of thousands in secret lodges. But its creed was narrow, its principles were illiberal, and its methods of procedure boyish and undignified. The great body of thinking men in the North saw that the real contest impending was against slavery and not against naturalization laws and ecclesiastical dogmas. The Know-Nothings, therefore, speedily disappeared, and a new party sprang into existence composed of anti-slavery Whigs and anti-slavery Democrats. The latter infused into the ranks of the new organization a spirit and an energy which Whig traditions could never inspire. The same name was not at once adopted in all the free States in 1854, but by the ensuing year there was a general recognition throughout the North that all who intended to make a serious fight against the pro-slavery Democracy would unite under the flag of the Republican party. In its very first effort, without compact organization, without discipline, it rallied the anti-slavery sentiment so successfully as to carry nearly all the free States and to secure a plurality of the members of the House of Representatives. The indignation of the people knew no bounds. Old political landmarks disappeared, and party prejudices of three generations were swept aside in a day. With such success in the outset, the Republicans prepared for a vigorous struggle in the approaching Presidential election.
