Clayton-Bulwer Treaty, signed by the United States and Britain in 1850, gave both countries an equal share in the protection of a canal to be built through Central America. Both countries agreed to maintain the neutrality of the canal and the land on either side of it. The treaty was named for John M. Clayton, American secretary of state, and Sir Henry Bulwer (1801-1872), British minister to the United States. It became unpopular in the United States. In 1901, the Hay-Pauncefote Treaty replaced the Clayton-Bulwer Treaty. It granted the United States the right to build and manage the canal. See also Hay-Pauncefote Treaty .
