Soconusco is a region in the southwest corner of the state of Chiapas in Mexico along its border with Guatemala. It is a narrow strip of land wedged between the Sierra Madre de Chiapas mountains and the Pacific Ocean. It is the southernmost part of the Chiapas coast extending south from the Ulapa River to the Suchiate River, distinguished by its history and economic production. In the 19th century, the area was disputed between Mexico and Guatemala until a treaty signed in 1882 fixed the modern border, dividing the area’s historical extension with most going to Mexico and a smaller portion south of the Suchiate to Guatemala. In 1890, Porfirio Diaz and Otto von Bismarck collaborated to take advantage of southern Mexico's agricultural potential by sending 450 German families to Soconusco near Tapachula in the southern state of Chiapas. Extensive coffee cultivation quickly made Soconusco one of the most successful German colonies, and between 1895 and 1900, 11.5 million kg of coffee had been harvested. Fincas (estates) were erected in the Chiapaneco jungle and given German names such as Hamburgo, Bremen, Lübeck, Agrovia, Bismarck, Prussia and Hanover.
