On April 20, 1980, the Castro regime announces that all Cubans wishing to emigrate to the U.S. are free to board boats at the port of Mariel west of Havana, launching the Mariel Boatlift. The first of 125,000 Cuban refugees from Mariel reached Florida the next day.
The boatlift was precipitated by housing and job shortages caused by the ailing Cuban economy, leading to simmering internal tensions on the island. On April 1, Hector Sanyustiz and four others drove a bus through a fence at the Peruvian embassy and were granted political asylum. Cuban guards on the street opened fire. One guard was killed in the crossfire.
The Cuban government demanded the five be returned for trial in the dead guard’s death. But when the Peruvian government refused, Castro withdrew his guards from the embassy on Good Friday, April 4. By Easter Sunday, April 6, some 10,000 Cubans crowded into the lushly landscaped gardens at the embassy requesting asylum. Other embassies, including those of Spain and Costa Rica, agreed to take a small number of people. But suddenly, two weeks later, Castro proclaimed that the port of Mariel would be opened to anyone wishing to leave, as long as they had someone to pick them up. Cuban exiles in the United States rushed to hire boats in Miami and Key West and rescue their relatives.
In all, 125,000 Cubans fled to U.S. shores in about 1,700 boats, creating large waves of people that overwhelmed the U.S. Coast guard. Cuban guards had packed boat after boat, without considering safety, making some of the overcrowded boats barely seaworthy. Twenty-seven migrants died, including 14 on an overloaded boat that capsized on May 17.
