Claim: The Clayton–Bulwer 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.
Evidence: The Clayton–Bulwer 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.
