The ClaytonBulwer Treaty provided that a canal might be constructed by the United States, or under its direction, which caused intense hostility in the U.S. to which Senator Henry G. Davis offered an  amendment.
The ClaytonBulwer Treaty was a treaty signed in 1850 between the United States and the United Kingdom. There were three main provisions in the treaty: neither nation would build such a canal without the consent and cooperation of the other; neither would fortify or found new colonies in the region; when a canal was built, both powers would guarantee that it would be available on a neutral basis for all shipping. The treaty proved instrumental in preventing the outbreak of war between the two nations-resolving tensions over American plans to construct a Nicaraguan Canal that would connect the Pacific and the Atlantic.
