The United States and Great Britain were pioneers in the use of arbitration to resolve their differences. It was first used in the Jay Treaty of 1795 negotiated by John Jay, and played a major role in the Alabama Claims case of 1872 whereby major tensions regarding British support for the Confederacy during the American Civil War were resolved. At the First International Conference of American States in 1890, a plan for systematic arbitration was developed, but not accepted. The Hague Peace Conference of 1899, saw the major world powers agreed to a system of arbitration and the creation of a Permanent Court of Arbitration.
