Key Facts

Spanish explorer Rodrigo de Bastidas was the first European to reach Panama's Atlantic coast in 1501, and Vasco Núñez de Balboa later became the first European to sight the Pacific Ocean from the Americas in 1513.
Panama declared independence from Spain in 1821 and joined Gran Colombia; when that federation dissolved, Panama remained a province of Colombia until 1903.
In 1903, with U.S. support following the failed French attempt by Ferdinand de Lesseps, Panama separated from Colombia and immediately signed the Hay-Bunau-Varilla Treaty granting the U.S. rights to build the canal.
The Panama Canal was completed in 1914 and revolutionized global shipping, but control remained a source of tension until the Torrijos-Carter Treaties of 1977 set the path for handover.
On December 31, 1999, Panama gained full control of the Panama Canal, and the country has since become one of Latin America's fastest-growing economies and a major international banking and logistics hub.
