A ceremony on May 4, 1905 marks the official beginning of the second attempt to build the Panama Canal. This second attempt to bridge the Atlantic and Pacific Oceans will succeed, dramatically altering world trade as well as the physical and geopolitical landscape of Central America.

For decades before it was attempted, merchants and engineers fixated on the idea of creating a passage through Central America for ocean-going vessels, sparing them thousands of nautical miles and the dangerous trip around Cape Horn. A French company was the first to attempt building such a canal, but the results were disastrous: roughly 20,000 workers perished due to accidents and tropical diseases, and the company collapsed without coming close to completing the canal.

In 1902, the United States Congress passed the Spooner Act, authorizing the acquisition of the defunct French company. After failing to reach a deal with Colombia to dig the canal, the Unites States backed separatists in the Isthmus of Panama, leading to the birth of a new nation as well as the Panama Canal Zone, a strip of land 10 miles wide along the route of the canal over which the United States would hold jurisdiction.
