Founded by Fernando Pacheco on February 29, 1756, Yauco was a center for Corsican immigration to Puerto Rico in the 19th century due to its geographical similarity to their homeland. Corsicans have contributed to many areas of life in Yauco, particularly its coffee-producing agriculture. This has contributed to its nicknames ofEl Pueblo del Café (City of Coffee), and Los Corsos (The Corsicans). It is also known as La Capital Taína (Taíno Capital) after the native peoples of Puerto Rico
