Corte's is the economic heartland of Honduras, as the Sula Valley is the country's main agricultural and industrial region. US banana companies arrived in the area in the late 19th Century, and established vast plantations, as well as infrastructure to ship the fruit to the United States. San Pedro Sula attracted substantial numbers of European, Central American, and Palestinian and Lebanese immigrants. Industry flourishes in the department, and Corte's today hosts most of the country's assembly plants, known as maquilas.
