History of the Panama Canal


The idea for a Panama canal dates back to the 1513 discovery of the isthmus by Vasco Núñez de Balboa. The narrow land bridge between North and South America houses the Panama Canal, a water passage between the Atlantic and Pacific Oceans. The earliest Central American European colonists recognized this potential, and several proposals for such a canal were made.

By the late nineteenth century, technological advances and commercial pressure allowed construction to begin in earnest. An initial attempt by France to build a sea-level canal failed after a great deal of excavation. This enabled the United States to complete the present canal in 1913 and open it to shipping the following year. The state of Panama was created with its 1903 emancipation from Colombia due to a US-backed revolt, so the US could control the canal-project area.

French canal engineer Philippe-Jean Bunau-Varilla influenced a change in its proposed location, from Nicaragua (the original US choice) to Panama because of his concern about Nicaraguan volcanism. During the late 1890s Bunaua-Varilla convinced US lawmakers to buy the rights to build the French canal in Panama, sending each senator Nicaragua postage stamps with a smoking volcano. In 1903, Colombia (which controlled Panama) refused to allow the United States to build the canal. The people of Panama, with help from Bunaua-Varilla, then overthrew their Colombian government and became independent (which made construction of the canal possible).

The Panama Canal continues to be a viable commercial venture and a vital link in world shipping. The 2007 Panama Canal expansion project began commercial operation on 26 June 2016. The new locks allow transit of larger Post-Panamax and New Panamax ships, which have a greater cargo capacity than the original locks could accommodate.
