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]
Panama Canal Colombia, France, and later the United States controlled the territory surrounding the canal during construction. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for handover to Panama. After a period of joint American–Panamanian control, in 1999, the canal was taken over by the Panamanian government and is now managed and operated by the government-owned Panama Canal Authority.
