French engineer Ferdinand de Lesseps completes work on the Suez Canal in Egypt. The canal allows a direct line of transportation and trade between Europe and Asia.
Also this year, President Ulysses S. Grant establishes the Inter-Oceanic Canal Commission (IOCC) and sends out an expedition to investigate possible routes for a canal. The idea of a canal will continue to be a priority for Grant throughout his presidency as he seeks a faster shipping route between the Atlantic and Pacific oceans.
A 100-man investigatory team from the U.S. surveys Panama -- then a part of the Republic of Colombia -- for a feasible canal route. They deem a Panama canal too expensive and propose a canal in Nicaragua with 12 locks at either end and 10 miles of aqueducts to supply water to the summit level.
Two years after a French team completes their own survey of Panama, their government approves Ferdinand de Lesseps' plan for a sea-level canal. The cost is estimated at 1.2 billion francs ($240 million).
With exclusive rights from Colombia, De Lesseps arrives in the Panama region and begins construction. The plan includes constructing a 40-meter high dam at Gamboa to hold back the Chagres River and a 24-meter wide path through the Culebra Cut.
In Havana, Cuba, Dr. Carlos Finlay identifies the mosquito as the carrier of yellow fever. This theory, however, will not catch on widely until the early 20th century.
French workers complete surveys and build accommodations and work yards as excavation begins.
Waylaid by flooding and landslides, the French team is behind schedule; only 660,000 cubic meters of earth have been excavated thus far, though de Lesseps had promised over 5 million cubic meters by this time.
An epidemic of yellow fever panics the workers. In 1883, an estimated 400 workers died of disease, compared with only 126 the year before.
More than 300 French engineers ask to return home and are denied.
An outbreak of dysentery cripples the already largely incapacitated workforce, affecting about 30% of workers. International press begins to openly doubt the French team's ability to complete the canal project.
Civil war in Colombia spreads to Panama and overwhelms French troops who have been enforcing order in the region.
Taking advantage of the confusion, a U.S. Navy ship docks in Colón and enforces order.
Racial tensions between native and Jamaican workers lead to a violent confrontation. Panamanian soldiers kill 25 Jamaicans and wound 20 others. The incident causes scores of Jamaicans to return home, and the canal becomes devoid of its primary source of manual laborers.
That summer, only 8 million cubic meters of earth will be excavated, out of the 120 required for the canal.
De Lesseps and a party from France and the United States visit Panama. De Lesseps predicts that the canal will be finished by July 1889.
Two months later, French engineer Armand Rousseau will submit a report to the French government concluding that the canal's completion is possible but a government lottery bill would do much to help fund the project. His report also hints at the unfeasibility of a sea-level canal. De Lesseps refuses to adopt the idea of a lock-canal plan.
After four years of excavations, only a few feet have been removed from the top of Culebra Cut out of the hundreds necessary to reach sea level.
Frustrated by the inefficiency of the excavation, De Lesseps hires Gustav Eiffel (who will become famous after the construction of the Eiffel Tower in 1889) to construct locks for the canal as a temporary solution while sea-level excavation continues.
After a nine-month fundraising campaign that included borrowing 30 million francs from friends and selling lottery tickets, de Lesseps runs out of money. His company, Compagnie Nouvelle, collapses, ruining the fortunes of 800,000 private investors.
Ferdinand de Lesseps and his son Charles are found guilty of fraud and maladministration of the Canal project. De Lesseps will die within two years, at the age of 89.
The stirring of a movement for Panama's independence begins with a meeting between Senator Arango, employees of the Panama Railroad, and American Army officers.
The idea will take hold over the course of the summer with the encouragement of U.S. conspirators.
A U.S. ship, the Nashville, arrives in Panama to provide support for the Panamanian revolution. Soon after, a Colombian ship named the Cartagena arrives in the port of Colón, filled with troops ordered to stop the rumors of Panamanian independence.
Panama claims its independence from Colombia a day after capturing the Colombian general Valencia Tovar and bribing troops remaining in Colón to leave the isthmus.
The United States formally recognizes the Republic of Panama two days later, and deploys Navy ships to protect the new country's autonomy and instill a sense of order.
The Hay-Bunau-Varilla Treaty, or Canal Treaty, is signed in the newly independent republic of Panama, giving the United States rights to build a canal on the Panamanian isthmus for an annual payment of $250,000.
President Roosevelt establishes the Isthmian Canal Commission (ICC) to see through the construction of the Panama Canal. Roosevelt orders them to "make the dirt fly" -- to start work on the canal as soon as possible.
The U.S. government purchases what is left of the French canal construction company, Compagnie Nouvelle, for $40 million.
A small U.S. workforce arrives in Panama to survey, plan, and continue the excavation begun by the French. They are led by Chief Engineer John Findley Wallace.
Chief Medical Officer Colonel William C. Gorgas arrives in Panama with a team of seven men. He immediately focuses on the staggering death rate the French had come across during their time on the isthmus, looking for possible causes. His studies on the local population will show that over 70% of the local Panamanian population has malaria.
Fearful of repeating the mistakes of corruption and ineptitude that plagued the French attempt, the ICC compulsively checks and rechecks requests. Every decision on canal construction must be cleared with each member of the Commission, a process that is laborious and time consuming.
The workforce in the canal zone swells to 3,500 men. At the end of the month, the U.S. attempts to recruit Jamaican workers but finds them hostile to the idea after a disastrous experience with the French.
The first Bucyrus steam shovel arrives in Colón, able to excavate five cubic yards of spoil in a single scoop. Despite the efficiency of the steam shovel, the 50-year old rail system proves incapable of carrying that amount of spoil away.
The first worker during the American effort in Panama contracts yellow fever. Six more will get the disease in December and eight more in January. As panic sets in, many engineers and workers resign and return to the U.S.
The U.S. sets up a recruiting agency in Barbados, and unskilled laborers flock to the Isthmus.
Frustrated by the ICC's bureaucratic red tape and the low productivity of a disease-ridden work force, Wallace resigns as chief engineer.
A Barbadian worker dies of bubonic plague, and the "Great Scare" begins.
Despite the doubts of U.S. politicians, William Gorgas stays committed to his theory that mosquitoes are transmitting malaria and yellow fever. Finally, with Roosevelt's backing, Gorgas' sanitation workforce is increased from 200 to 2,000 men this month. He begins a complete eradication effort of the Aëdes aegypti mosquito, fumigating homes with his "mosquito brigades."
New Chief Engineer John Stevens arrives in Panama stressing the importance of satisfactory accommodations and sanitation before construction can be continued. He immediately places an order for new, state-of-the-art equipment to improve the rate of excavation.
With the rusty and decrepit Panama Railroad now 60 years old, Stevens realizes he is unable to cart out the spoil at the same furious rate the canal is being dug. Stevens orders all excavation in Culebra Cut to be temporarily halted and turns his attention toward the repair of the railroad.
Three thousand Barbadian workers are now in Panama.
By the following month, the rapid inflation of food prices will lead to the malnutrition of many West Indian workers. Twenty-six catch pneumonia.
The last death from yellow fever is reported in Panama City after Gorgas orders $90,000 worth of copper screening to protect workers from mosquito bites.
Despite considerable progress with excavation, U.S. engineers still have not decided on the best way to build the canal.

Workers begin clearing the site for the Gatún Dam.
The ICC sets up recruiting agencies in Spain and Italy, which will result in over 12,000 contracts with European workers in unskilled labor positions. Spanish men, in particular, develop a reputation for working hard.
Despite the strides made in fighting yellow fever, disease is still a problem. Daily, over 75 workers come to the Ancón hospital suffering from malaria. Over 80 die of pneumonia this month alone.
President Roosevelt visits Panama to see the progress. This marks the first time a sitting president leaves the U.S.
While in Panama, Roosevelt signs an executive order to rework the ICC commission yet again. This streamlines the process for Stevens', who is no longer required to get ICC clearances for every decision.
Roosevelt updates Congress on the successes and challenges in Panama. He lauds Stevens' leadership and announces a Medal as an incentive to keep workers from abandoning their posts.
After the railroad system is overhauled and worker accommodations are improved, excavation begins again. Sixty-three more Bucyrus shovels arrive in Panama and are immediately put to work. By the end of the month, over 500,000 cubic yards of spoil are excavated out of Culebra Cut.
Despite a tremendous leap in the engineering of the canal, Stevens has reached a breaking point. His expertise in railroad engineering, he realizes, is no longer needed, and the massive canal he faces is, as he writes in a letter to President Roosevelt, "to me… only a big ditch." Roosevelt accepts the note as Steven's resignation.
Roosevelt selects Lieutenant Colonel George Goethals to be the third Chief Engineer of the canal.
Over 800,000 cubic yards are excavated this month alone.
