Afro-Panamanian
In 1904 when the construction of the Panama Canal was taken over by the United States for the failure of the French company, will again resort to the West Indian worker. Although between 1904 and 1914 the vast majority of Afro-West Indians who arrived in Panama did a one-year contract with the idea of returning to their home islands once the offshore project, after construction of the canal many Afro-Antillean stayed in Panama. Afro-West Indians who remained in Panama many got jobs in the Canal Zone and became the largest immigrant group in Panama. On the subject of Afro-Antillean Panama, Leslie B. Rout said that when the canal was opened in 1914, some 20,000 African-West Indians remained in Panama.
Panama–United States relations
The evolution of the relation between Panama and the USA has followed the pattern of a Panamanian project for the recovering of the territory of the Canal of Panama, a project which became public after the events of May 21, 1958, November 3, 1959, and then on January 9, 1964. The latter day is known in Panama as the Martyrs' Day (Panama), in which a riot over the right to raise the Panamanian flag in an American school became the vicinity of the Panama Canal.
