Which two countries were responsible for the construction of the Panama Canal

Building the Panama Canal, 1903–1914

To that end, in 1850 the United States and Great Britain negotiated the Clayton-Bulwer Treaty to rein in rivalry over a proposed canal through the Central American Republic of Nicaragua.

Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of engineering problems and a high worker mortality rate. The United States took over the project in 1904 and opened the canal on August 15, 1914.
