The Torrijos–Carter Treaties, signed in 1977, are among the most significant agreements in Panama’s modern history. They resolved a decades-long dispute over sovereignty and set a clear timeline for transferring the Panama Canal and the surrounding Canal Zone from the United States to Panama.
Roots of the Conflict
When the Canal opened in 1914, it was controlled by the United States under the Hay–Bunau-Varilla Treaty of 1903, which granted the U.S. rights over a Canal Zone “in perpetuity.” A strip of U.S.-administered territory ran through the heart of Panama, and many Panamanians viewed it as a violation of national sovereignty.
Tensions built for decades. They erupted tragically in January 1964, when clashes over the flying of the Panamanian flag in the Zone led to deadly riots. The events, remembered as a national turning point, intensified demands for a new arrangement.
Negotiating a New Deal
By the 1970s, Panama’s leader General Omar Torrijos made recovering the Canal a central goal, pressing the issue on the world stage. In the United States, President Jimmy Carter saw resolving the dispute as both a matter of fairness and a way to improve U.S. relations with Latin America.
On September 7, 1977, Torrijos and Carter signed two treaties in Washington, D.C.
What the Treaties Said
- The Panama Canal Treaty provided for the gradual transfer of the Canal to Panamanian control, with full control to pass to Panama on December 31, 1999. It also abolished the Canal Zone and returned that territory to Panama.
- The Treaty Concerning the Permanent Neutrality and Operation of the Canal guaranteed that the Canal would remain permanently neutral and open to ships of all nations, with the United States retaining the right to defend that neutrality.
A Hard-Won Ratification
The treaties were controversial in both countries. In Panama they were approved by a national vote. In the United States the Senate ratified them in 1978 after intense debate, narrowly meeting the required two-thirds majority.
The Handover of 1999
Over the following two decades, control was gradually handed over. Torrijos himself died in a plane crash in 1981 and did not see the final transfer. On December 31, 1999, Panama assumed full sovereignty over the Canal, which has since been operated by the Panama Canal Authority. The successful, efficient operation of the Canal under Panamanian management stands as a source of national pride.
