The Lord Eliot Convention, or simply the Eliot Convention or Eliot Treaty (Spanish: Convenio Lord Eliot), was an April 1835 agreement brokered by Edward Eliot, 3rd Earl of St Germans between the two opposing sides of Spain's First Carlist War. It had as its aim not to end the war itself but to end the indiscriminate executions of prisoners of war by firing squad that had been committed by both sides.
Edward Eliot had become Secretary of Legation at Madrid on 21 November 1821 and was styled Lord Eliot in 1826.[1]
