Before the arrival of Spanish colonists in the 16th century, Panama was inhabited by a number of different indigenous tribes. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of Engineers between 1904 and 1914. The 1977 Torrijos–Carter Treaties agreed to transfer the canal from the United States to Panama on December 31, 1999. The surrounding territory was first returned in 1979.
Omar Efraín Torrijos Herrera (February 13, 1929 – July 31, 1981) was a Panamanian dictator, as well as the Commander of the Panamanian National Guard and military leader of Panama from 1968 to his death in 1981. Torrijos was never officially the president of Panama, but instead held titles including "Maximum Leader of the Panamanian Revolution". Torrijos took power in a coup d'état and instituted a number of social reforms.
Torrijos is best known for negotiating the 1977 Torrijos–Carter Treaties that eventually gave Panama full sovereignty over the Panama Canal. The two treaties guaranteed that Panama would gain control of the Panama Canal after 1999, ending the control of the canal that the U.S. had exercised since 1903. On December 31, 1999, the final phase of the treaty, the US relinquished control of the Panama Canal and all areas in what had been the Panama Canal Zone. (Full article...)
