north and west) who opposed large national institutions. In 1787, Alexander Hamilton, a leading Federalist from New York and signatory to the Constitution, wrote the first essay of the Federalist Papers. He published and wrote most of the series in New York City newspapers in support of the proposed United States Constitution. Antifederalists were not swayed by the arguments, but the state ratified it in 1788. In 1785, New York City became the national capital and continued as such on and off until 1790; George Washington was inaugurated as the first President of the United States in front of Federal Hall in 1789. The United States Bill of Rights was drafted there, and the United States Supreme Court sat for the first time. From statehood to 1797, the Legislature frequently moved the state capital between Albany, Kingston, Poughkeepsie, and New York City. Thereafter, Albany retained that role. In the early 19th century, New York became a center for advancement in transportation. In 1807, Robert Fulton initiated a steamboat line from New York to Albany, the first successful enterprise of its kind. By 1815, Albany was the state's turnpike center, which established the city as the hub for pioneers migrating west to Buffalo and the Michigan Territory. In 1825 the Erie Canal opened, securing the state's economic dominance. Its impact was enormous: one source stated, "Linking the Atlantic Ocean and the Great Lakes, the canal was an act of political will that joined the regions of the state, created a vast economic hinterland for New York City, and established a ready market for agricultural products from the state's interior." In that year western New York transitioned from "frontier" to settled area. By this time, all counties and most municipalities had incorporated, approximately matching the state's is organized today. In 1831, the Mohawk and Hudson Railroad started the country's first successful regularly–scheduled steam railroad service. Advancing transportation quickly led to settlement of the fertile Mohawk and Gennessee valleys and the Niagara Frontier. Buffalo and Rochester became boomtowns. Significant migration of New England "Yankees" (mainly of English descent) to the central and western parts of the state led to minor conflicts with the more settled "Yorkers" (mainly of German, Dutch, and Scottish descent). More than 15% of the state's 1850 population had been born in New England . The western part of the state grew fastest at this time. By 1840, New York
