Washington presided over the establishment of the new federal government, appointing all of the high-ranking officials in the executive and judicial branches, shaping numerous political practices, and establishing the site of the permanent capital of the United States. He supported Alexander Hamilton's economic policies whereby the federal government assumed the debts of the state governments and established the First Bank of the United States, the United States Mint, and the United States Customs Service. Congress passed the Tariff of 1789, the Tariff of 1790, and an excise tax on whiskey to fund the government and, in the case of the tariffs, address the trade imbalance with Britain. Washington personally led federalized soldiers in suppressing the Whiskey Rebellion, which arose in opposition to the administration's taxation policies. He directed the Northwest Indian War, which saw the United States establish control over Native American tribes in the Northwest Territory. In foreign affairs, he assured domestic tranquility and maintained peace with the European powers despite the raging French Revolutionary Wars by issuing the 1793 Proclamation of Neutrality. He also secured two important bilateral treaties, the 1794 Jay Treaty with Great Britain and the 1795 Treaty of San Lorenzo with Spain, both of which fostered trade and helped secure control of the American frontier. To protect American shipping from Barbary pirates and other threats, he re-established the United States Navy with the Naval Act of 1794.
