Lansing studied law with
Robert Yates in Albany, and was admitted to practice in 1775. From 1776 until 1777 during the
Revolutionary War, Lansing served as a military secretary to General
Philip Schuyler. In 1786, Lansing was appointed
Mayor of Albany. He represented New York as one of three representatives at the
Constitutional Convention in 1787, where he intended to follow the wishes of the
New York Legislature and only amend the existing
Articles of Confederation. However, as the convention progressed he became dismayed that the convention was, in his view, exceeding of its mandate by writing an entirely new constitution. Lansing's desire was to see the Articles strengthened by giving it a source of revenue, the power to regulate commerce, and to enforce treaties. He joined other prominent
Anti-Federalists that strongly opposed
Alexander Hamilton,
James Wilson, and
James Madison's notions of a strong centralized national government to replace the Articles. Neither man signed the constitution. At the New York Ratifying Convention that followed, Lansing, along with
Melancton Smith, took the lead in the debates as the leaders of the Anti-Federalist majority. Their attempts to prevent ratification ultimately failed by a narrow vote of 30 to 27. Lansing was appointed a justice of the
New York State Supreme Court in 1790, and on February 15, 1798, he was elevated to the post of chief justice. == Disappearance ==
