Since the Panama Canal has been in the news lately, I thought a little history would be interesting.
The Panama Canal, a 50-mile, man-made waterway connecting the Atlantic and Pacific Oceans, has a complex history rooted in global trade ambitions, engineering feats, and geopolitical struggles.
The idea of a canal across Central America began in the 1500s when Spanish explorers, like Vasco Núñez de Balboa, saw the importance of connecting the Atlantic and Pacific Oceans. In 1534, Holy Roman Emperor Charles V had a survey done for a possible route, but the technology and resources of the time made it impractical. Over the years, Spain, Scotland (with the unsuccessful Darien Scheme of 1698–1700), and later the United States looked at the area for trade routes.
By the 19th century, the Industrial Revolution and growing global commerce amplified the need for a shorter maritime route. The United States, after its westward expansion and the California Gold Rush (1848–1855), relied heavily on lengthy ship journeys around South America. In 1855, the U.S.-built Panama Railway demonstrated the isthmus’s potential, but a canal remained the ultimate goal.
In 1879, French engineer Ferdinand de Lesseps, after his success with the Suez Canal, got permission from Colombia to build a sea-level canal in Panama. The Compagnie Universelle du Canal Interocéanique started work in 1881 but faced challenges like dense jungles, mountains, and heavy rain that caused landslides. Diseases like malaria and yellow fever killed about 20,000 workers. The company went bankrupt in 1889, causing a scandal in France. A second French company tried to continue the work but failed by 1894, leaving behind some excavations and equipment.
By the late 19th century, the U.S. emerged as a global power, eager to secure a canal for naval and commercial purposes essential for enhancing trade routes and military mobility. After the Spanish-American War (1898), control of a canal became a strategic priority. This was driven by the need to allow faster passage of naval fleets between the Atlantic and Pacific Oceans, thereby bolstering the nation’s presence in foreign waters. Two routes were considered: Nicaragua and Panama. Panama was ultimately chosen due to its shorter distance and existing French infrastructure, which included partially constructed locks and railway systems, making it a more viable option for rapid development. The decision was also influenced by geopolitical considerations, as controlling this canal would not only facilitate commerce but also assert American dominance in the Western Hemisphere.
Colombia opposed U.S. control over a canal zone. In 1903, the U.S. backed a movement for Panama’s independence led by local leaders like Philippe Bunau-Varilla. With U.S. naval support, Panama became independent from Colombia on November 3, 1903. Soon after, Panama signed the Hay-Bunau-Varilla Treaty, allowing the U.S. to control a 10-mile-wide Canal Zone for $10 million and annual payments.
The U.S. began construction in 1904, learning from French failures. Key developments included:
- Health measures: Dr. William Gorgas led a campaign to eradicate malaria and yellow fever by controlling mosquitoes, drastically reducing worker deaths.
- Engineering shift: Engineer John Frank Stevens advocated for a lock-based canal over a sea-level design, addressing Panama’s uneven terrain and Chagres River flooding. George Washington Goethals oversaw completion.
- Labor: Over 75,000 workers, primarily from the Caribbean, endured harsh conditions. Racial segregation and unequal pay sparked tensions.
The canal’s lock system, with massive concrete chambers lifting ships 85 feet to Gatun Lake, was an engineering marvel. On August 15, 1914, the SS Ancon made the first official transit. The project cost $375 million and claimed over 5,600 lives, mostly from disease and accidents.
The Panama Canal became a linchpin of global trade and U.S. military strategy, handling 5% of world commerce by the 1930s. The U.S. fortified the Canal Zone, treating it as a de facto colony, which fueled Panamanian resentment. Tensions erupted in the 1964 flag riots, where Panamanian students protested U.S. control, leading to 21 deaths.
Negotiations for Panamanian sovereignty began in the 1960s. In 1977, President Jimmy Carter and Panamanian leader Omar Torrijos signed the Torrijos-Carter Treaties, agreeing to transfer canal control to Panama by December 31, 1999, with the U.S. retaining rights to defend the canal’s neutrality.
Panama assumed full control on December 31, 1999, operating the canal through the Panama Canal Authority. The canal has since been modernized, with a $5.25 billion expansion completed in 2016. This added larger locks, doubling capacity to accommodate “New Panamax” ships carrying up to 14,000 containers.
Today, the canal handles about 6% of global trade, with over 14,000 transits annually. It remains a critical artery for U.S., Chinese, and Latin American commerce, generating significant revenue for Panama. However, challenges like droughts affecting water levels and competition from Arctic routes and Nicaragua’s proposed canal persist.
The Panama Canal’s history reflects a saga of ambition, sacrifice, and innovation, shaping global trade and geopolitics for over a century.
