Signed in 1850
by the United States
and Great Britain
, the Clayton-Bulwer Treaty
was an agreement that both nations were not to colonize or control any Central American
republic. The purpose was to prevent one country from building a canal
across Central America that the other would not be able to use. If a canal were built, it would be protected by both nations for neutrality and security. Any canal built would be open to all nations on equal terms.
