"As after any revolution, purists were vigilant for signs of ideological backsliding and departures from the one true faith. The 1780s and 1790s were to be especially rich in feverish witch hunts for traitors who allegedly sought to reverse the verdict of the war. For the radicals of the day, revolutionary purity meant a strong legislature that would overshadow a weak executive and judiciary. For Hamilton, this could only invite legislative tyranny. Rutgers v. Waddington represented his first major chance to expound the principle that the judiciary should enjoy coequal status with the other two branches of government. If Rutgers v. Waddington made Hamilton a controversial figure in city politics in 1784, the founding of the Bank of New York cast him in a more conciliatory role. The creation of New York's first bank was a formative moment in the city's rise as a world financial center. Banking was still a new phenomenon in America. The first such chartered institution, the Bank of North America, had been started in Philadelphia in 1781, and Hamilton had studied its affairs closely. It was the brainchild of Robert Morris, and its two biggest shareholders were Jeremiah Wadsworth and Hamilton's brother-in-law John B. Church. These two men now cast about for fresh outlets for their capital. In 1783, John Church sailed for Europe with Angelica and their four children to settle wartime accounts with the French government. In his absence, Church named Hamilton as his American business agent, a task that was to consume a good deal of his time in coming years. When Church and Wadsworth deputized him to set up a private bank in New York, Hamilton warmed to it as a project that could help to rejuvenate New York commerce. He was stymied by a competing proposal from Robert R. Livingston to set up a "land bank"--so called because the initial capital would be pledged mostly in land, an idea Hamilton derided as a "wild and impracticable scheme." 49 Since land is not a liquid asset and cannot be converted into ready cash in an emergency, Hamilton favored a more conservative bank that would conduct business exclusively in notes and gold and silver coins. When Livingston solicited the New York legislature for a charter, the tireless Hamilton swung into action and mobilized New York's merchants against the effort. He informed Church that he had lobbied "some of the most intelligent merchants, who presently saw the matter in a proper light and began to take measures to defeat the plan."
