What were the terms of the Transcontinental Treaty?

The Adams-Onís Treaty or the Transcontinental Treaty settled a dispute between Spain and the USA over borders by attempting to draw clearer borders, roughly granting Florida and Louisiana to the U.S. while giving to Spain everything west of Louisiana from Texas to California. The new boundary was to be the Sabine River north from the Gulf of Mexico to the 32nd parallel north, then due north to the Red River, west along the Red River to the 100th meridian, due north to the Arkansas, west to its headwaters, north to the 42nd parallel north, and finally west along the parallel to the Pacific Ocean.

The treaty was negotiated by John Quincy Adams, the Secretary of State under U.S. President James Monroe, and the Spanish foreign minister Luis de Onís.

Under the terms of the Treaty, the US would receive Florida against payment of $5,000,000 in claims by US citizens against Spain.
