The Clayton–Bulwer Treaty was a treaty signed in 1850 between the United States and the United Kingdom. The treaty was negotiated by John M. Clayton and Sir Henry Bulwer, amidst growing tensions between the two nations over Central America. There were three main provisions in the treaty: neither nation would build such a canal without the consent and cooperation of the other. Construction on the proposed canal never came to fruition, although the treaty remained in effect until 1901.
