In the 1920s, settlers from Antioquia moved to Pereira for its economically strategic location, fertile soil, and good weather. The settlers grew large quantities of high-quality coffee in the mineral-rich, volcanic Andean soil. Other produce included sugarcane and cattle. Settlers also came from cities such as Valle del Cauca and Bogotá. In the 1950s, during a period of bipartisan political struggle in the country, Pereira became a refuge for thousands of Colombians, quadrupling its population and creating a national melting pot that changed its community forever. In recent years, the city has achieved an urban identity and a significant growth in its cultural development. Social integration and higher levels of education are providing the city sustained economic and cultural growth.
