Tammany soon became partizan. The Federalist members withdrew, probably influenced by Washington's warning against secret political societies. By 1798 it was a Republican club meeting in various taverns, finally selecting Martling's "Long Room" for its nightly carousals. Soon after this a new constitution was adopted which adroitly transformed the society into a compact political machine, every member subscribing to the oath that he would resist the encroachments of centralized power over the State.
Tradition has it that the transformer of Tammany into the first compact and effective political machine was Aaron Burr. There is no direct evidence that he wrote the new constitution. But there is collateral evidence. Indeed, it would not have been Burrian had he left any written evidence of his connection with the organization. For Burr was one of those intriguers who revel in mystery, who always hide their designs, and never bind themselves in writing without leaving a dozen loopholes for escape. He was by this time a prominent figure in American politics. His skill had been displayed in Albany, both in the passing of legislation and in out-maneuvering Hamilton and having himself elected United States Senator against the powerful combination of the Livingstons and the Schuylers. He was plotting for the Presidency as the campaign of 1800 approached, and Tammany was to be the fulcrum to lift him to this conspicuous place.
Under the ostensible leadership of Matthew L. Davis, Burr's chief lieutenant, every ward of the city was carefully organized, a polling list was made, scores of new members were pledged to Tammany, and during the three days of voting (in New York State until 1840 elections lasted three days), while Hamilton was making eloquent speeches for the Federalists, Burr was secretly manipulating the wires of his machine. Burr and Tammany won in New York City, though Burr failed to win the Presidency. The political career of this remarkable organization, which has survived over one hundred and twenty years of stormy history, was now well launched.
From that time to the present the history of Tammany Hall is a tale of victories, followed by occasional disclosures of corruption and favoritism; of quarrels with governors and presidents; of party fights between "up-state" and "city"; of skulking when its sachems were unwelcome in the White House; of periodical displays of patriotism for cloaking its grosser crimes; of perennial charities for fastening itself more firmly on the poorer populace which has always been the source of its power; of colossal municipal enterprise for profit-sharing; and of a continuous political efficiency due to sagacious leadership, a remarkable adaptability to the necessities of the hour, and a patience that outlasts every "reform."
It early displayed all the traits that have made it successful. In 1801, for the purpose of carrying city elections, it provided thirty-nine men with money to purchase houses and lots in one ward, and seventy men with money for the same purpose in another ward, thus manufacturing freeholders for polling purposes. In 1806 Benjamin Romaine, a grand sachem, was removed from the office of city controller by his own party for acquiring land from the city without paying for it. In 1807 several superintendents of city institutions were dismissed for frauds. The inspector of bread, a sachem, resigned because his threat to extort one-third of the fees from his subordinates had become public. Several assessment collectors, all prominent in Tammany, were compelled to reimburse the city for deficits in their accounts. One of the leading aldermen used his influence to induce the city to sell land to his brother-in-law at a low price, and then bade the city buy it back for many times its value. Mooney, the founder of the society, now superintendent of the almshouse, was caught in a characteristic fraud. His salary was $1000 a year, with $500 for family expenses. But it was discovered that his "expenses" amounted to $4000 a year, and that he had credited to himself on the books $1000 worth of supplies and numerous sums for "trifles for Mrs. Mooney."
In September, 1826, the Grand Jury entered an indictment against Matthew L. Davis and a number of other Tammany men for defrauding several banks and insurance companies of over $2,000,000. This created a tremendous sensation. Political influence was at once set in motion, and only the minor defendants were sent to the penitentiary.
In 1829 Samuel Swartwout, one of the Tammany leaders, was appointed Collector of the Port of New York. His downfall came in 1838, and he fled to Europe. His defalcations in the Custom House were found to be over $1,222,700; and "to Swartwout" became a useful phrase until Tweed's day. He was succeeded by Jesse Hoyt, another sachem and notorious politician, against whom several judgments for default were recorded in the Superior Court, which were satisfied very soon after his appointment. At this time another Tammany chieftain, W. M. Price, United States District Attorney for Southern New York, defaulted for $75,000.
It was in 1851 that the council commonly known as "The Forty Thieves" was elected. In it William M. Tweed served his apprenticeship. Some of the maneuvers of this council and of other officials were divulged by a Grand Jury in its presentment of February 23, 1853. The presentment states: "It was clearly shown that enormous sums of money were spent for the procurement of railroad grants in the city, and that towards the decision and procurement of the Eighth Avenue railway grant, a sum so large that would startle the most credulous was expended; but in consequence of the voluntary absence of important witnesses, the Grand Jury was left without direct testimony of the particular recipients of the different amounts."
These and other exposures brought on a number of amendments to the city charter, surrounding with greater safeguards the sale or lease of city property and the letting of contracts; and a reform council was elected. Immediately upon the heels of this reform movement followed the shameful regime of Fernando Wood, an able, crafty, unscrupulous politician, who began by announcing himself a reformer, but who soon became a boss in the most offensive sense of that term—not, however, in Tammany Hall, for he was ousted from that organization after his reelection as mayor in 1856. He immediately organized a machine of his own, Mozart Hall. The intense struggle between the two machines cost the city a great sum, for the taxpayers were mulcted to pay the bills.
Through the anxious days of the Civil War, when the minds of thoughtful citizens were occupied with national issues, the tide of reform ebbed and flowed. A reform candidate was elected mayor in 1863, but Tammany returned to power two years later by securing the election and then the reelection of John T. Hoffman. Hoffman possessed considerable ability and an attractive personality. His zeal for high office, however, made him easily amenable to the manipulators. Tammany made him Governor and planned to name him for President. Behind his popularity, which was considerable, and screened by the greater excitements of the war, reconstruction, and the impeachment of Andrew Johnson, lurked the Ring, whose exposures and confessions were soon to amaze everyone.
