La Unión () is a municipality in La Unión Department of El Salvador. It is the capital city of the department of La Unión. It is the largest city in the department with a population of approximately 34,000 inhabitants. Previously known as Puerto San Carlos, it was renamed La Unión on July 13, 1824 after El Salvador gained independence from Spain and formed the United Provinces of Central America. La Unión became a department on June 22, 1865, and the city of La Unión became its capital. In 2005 the Salvadoran government began a new port at La Unión which was to have more than double the cargo capacity of the old and exceed that of El Salvador's principal port at Acajutla. Completed in November 2012, the port has since helped increase local economic growth and stability, though competition from nearby San Miguel remains strong. On Nov. 20, 2021 Salvadoran President Nayib Bukele announced plans to construct a new city, dubbed a "Bitcoin City", in La Unión. History In 1522, Andrés Niño, a pilot, discovered the Golfo de Fonseca. At the end of the 18th century, what is now La Unión was categorized as a town and it was given the name in honor the King, who at the time was Charles III. On February 28, 1854 the town, now La Unión, was granted with the title of city as "pueblo del puerto de San Carlos de la Unión." After El Salvador gained its independence, the extensive Departamento de San Miguel was created. Eventually, this overly large department was split into two: San Miguel proper, a new Department of La Unión, with its capital at the Port of La Unión. Agriculture On the basis of agriculture, La Unión is one of the richest departments with this industry. The most important products that have been grown are: coffee, cocoa, sugar cane, oleaginous seeds, fruits, and grass.
