Panama Canal
France began work on the canal in 1881, but stopped due to 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. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduced the time for ships to travel between the Atlantic and Pacific Oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan.
Panama–United States relations
The evolution of the relation between Panama and the USA has followed the pattern of a Panamanian project for the recovering of the territory of the Canal of Panama, a project which became public after the events of May 21, 1958, November 3, 1959, and then on January 9, 1964. The latter day is known in Panama as the Martyrs' Day (Panama), in which a riot over the right to raise the Panamanian flag in an American school became the vicinity of the Panama Canal.
