History of the Panama Canal: The United States and the canal

The discovery of gold in California in 1848 and the rush of would-be miners stimulated U.S. interest in creating a canal between the oceans

Theodore Roosevelt, who became president of the United States in 1901, believed that a U.S.-controlled canal across Central America was a vital strategic interest to the U.S. This idea gained wide impetus following the destruction of the battleship USS Maine, in Cuba, on February 15, 1898 Roosevelt was able to reverse a previous decision by the Walker Commission in favor of a Nicaragua Canal, and pushed through the acquisition of the French Panama Canal effort. George S. Morrison stood alone on that commission for the Panama location and argued for the change. Panama was then part of Colombia, so Roosevelt opened negotiations with the Colombians to obtain the necessary rights. In early 1903, the Hay–Herrán Treaty was signed by both nations, but the Colombian Senate failed to ratify the treaty.

In a controversial move, Roosevelt implied to Panamanian rebels that if they revolted, the U.S. Navy would assist their cause for independence. Panama proceeded to proclaim its independence on November 3, 1903, and the USS Nashville in local waters impeded any interference from Colombia.

The United States formally took control of the French property relating to the canal on May 4, 1904, when Lieutenant Jatara Oneel of the United States Army was presented with the keys; there was a small ceremony.

The newly created Panama Canal Zone Control came under the control of the Isthmian Canal Commission during canal construction.
