In 1848 he led the revolt of the Democratic party in New York State against the creation of five slave States, with their ten slave-holding Senators, out of the Territory of Texas. Among the immediate results of this revolt were the defeat of General Cass, the Democratic candidate for President, and the development of a Free-soil party, which later took the name of the Republican, nominated and elected Abraham Lincoln to the Presidency--synchronously with which, and for the first time in the nation's history, the decennial census of 1860 disclosed the fact that the political supremacy of the nation had been transferred to the non-slave-holding States. Though averse to resisting the secession of the slave States by flagrant war, Tilden did his best and much during the war to prevent an irreconcilable alienation of the people of the two sections, while at the same time building up for himself a reputation in his profession scarcely second to that of any other in the country; and by it, before he had reached the fiftieth year of his age, a fortune which made him no longer dependent upon it for his livelihood. The first public use he made of this independence was to retrieve the fortunes of the Democratic party by delivering the city of New York from a municipal combination which was threatening it with bankruptcy. Of Tilden's many achievements as a public servant, it may well be doubted if there was any for which he deserves so much honor as for his part in the overthrow of this pillaging combination, familiarly known as the Tweed Ring, nor any for which it seems so entirely impossible to have then provided another equally competent leader who could and would have given the time, incurred the expense, and assumed the risks that Mr. Tilden did when, with no personal advantage in view, he boldly consecrated several of what might have been the most lucrative years of his professional life to this desperate battle with intrenched municipal villany. The people of the State were not slow to realize that a man with the courage, power, and resources exhibited by Mr. Tilden in this memorable conflict was precisely the kind of man needed by them for Governor; and while yet wearied with the fatigue and covered with the dust of this municipal struggle, he was constrained by his admirers to enter the lists as a candidate against General Dix, the Republican candidate for that office. The result was a change of about 100,000 votes from the number by which Governor Dix had been elected two years before, and Tilden's triumphant election to his place.
