It terminated April 14, 1903, by a treaty of July 3, 1902. The treaty was named for John Quincy Adams of the United States and Louis de Onís of Spain and renounced any claim of the United States to Texas. It fixed the western boundary of the Louisiana Purchase as beginning at the mouth of the Sabine River and running along its south and west bank to the thirty-second parallel and thence directly north to the Río Rojo (Red River).
