How did US get the right to build panama canal in history?

The construction of the Panama Canal was a momentous endeavour that reshaped the course of global trade and geopolitics. The following is a historical account of how the United States acquired the rights to build the Panama Canal:

1. French Involvement: In the 1870s, a French company obtained a concession from Colombia (which then controlled the Isthmus of Panama) to construct a canal across the isthmus. The French embarked on an ambitious project, but faced numerous engineering and financial challenges, leading to the eventual collapse of their efforts.

2. Hay-Herrán Treaty: The United States recognized the strategic significance of a canal across the isthmus and sought to take over the canal project from the French. In 1903, Secretary of State John Hay negotiated the Hay-Herrán Treaty with Colombia, granting the US exclusive rights to construct, operate, and defend a canal.

3. Panamanian Independence and US Support: Colombian legislators rejected the Hay-Herrán Treaty, viewing it as detrimental to their national interests. This development set the stage for a significant turn of events. Certain pro-American Panamanian factions, with encouragement and covert support from the United States, declared the independence of Panama from Colombia in 1903.

4. US and Panama Reach Agreement: Almost immediately, the United States recognized the new Republic of Panama and promptly signed a treaty known as the Hay-Bunau-Varilla Treaty. This agreement granted the United States extensive rights to perpetuity, including the construction of a canal across Panama and perpetual control of a zone on each side of the canal (the Panama Canal Zone).

5. Construction and US Sovereignty: The United States assumed control of the canal zone and began construction of the Panama Canal. The project was completed in 1914, significantly altering global maritime routes and reducing travel times between the Atlantic and the Pacific Oceans. For several decades, the United States maintained jurisdiction over the canal and the Panama Canal Zone, exercising its sovereign rights and responsibilities.

6. Transfer of Canal to Panama: In the late 20th century, a growing independence movement in Panama sought the return of the canal and its associated territories. Through diplomatic negotiations, the United States and Panama reached an agreement culminating in the signing of the Panama Canal Treaties of 1977. These treaties stipulated the transfer of the canal and the Panama Canal Zone from the United States to Panama by the end of the 20th century.

On December 31, 1999, the Panama Canal was officially transferred to Panama, marking a significant milestone in Panamanian history and sovereignty. However, the United States retained certain rights and responsibilities, including the military defense of the canal and oversight of its neutrality, as outlined in the Panama Canal Treaties.
