The Cacaopera people also known as the Matagalpa or Ulúa., are an indigenous people in what is now El Salvador and Nicaragua. History The Matagalpa are one of the most important cultures in the historical development of the Nicaraguan territory, but they lack precise information that can legitimize their ethnic origin. Most of the studies carried out on this original group have achieved great advances, but they always remain empty that they do not allow to indicate with certainty said origin. The strongest theory is that which attributes the Matagalpa are of Chibcha origin from South America. Their cultivation of cacao, corn and beans show some Mesoamerican influence. However, historians believe their ceramic style known as "Ceramica Negra" and "Naranja Segovia" show Mayan influence and have been found in abundance in towns near Estelí.
