when did the us give up the panama canal
Panama Canal Zone On February 26, 1904, the Isthmian Canal Convention was proclaimed. In it, the Republic of Panama granted to the United States in perpetuity the use, occupation, and control of a zone of land and land under water for the construction, maintenance, operation, sanitation, and protection of the canal. From 1903 to 1979 the territory was controlled by the United States, which had purchased the land from the private and public owners, built the canal and financed its construction. The Canal Zone was abolished on October 1, 1979, as a term of the Torrijos–Carter Treaties of 1977; the canal itself was under joint U.S.–Panamanian control from 1979 until it was fully turned over to Panama on December 31, 1999.[2]
Latin America–United States relations As unrest in Cuba escalated in the 1890s, the United States demanded reforms that Spain was unable to accomplish. The result was the short Spanish–American War of 1898, in which United States acquired Puerto Rico and set up a protectorate over Cuba under the Platt Amendment rule passed as part of the 1901 Army Appropriations Bill. The building of the Panama Canal absorbed American attention from 1903. The US facilitated a revolt that made Panama independent and set up the Panama Canal Zone as an American owned and operated district that was finally returned to Panama in 1979. The Canal opened in 1914 and proved a major factor in world trade. The United States paid special attention to protection of the military approaches to the Panama Canal, including threats by Germany. Repeatedly it seized temporary control of several countries, especially Haiti and Nicaragua.
