Medellín, as the capital of the Antioquia Department, main economic center and host of most of local government entities contributed to a rapid urban development which absorbed many corregimientos such as Robledo, La América, La Floresta, Guayabal, and Belén, among others. With the industrialization the middle and higher class moved to the southern parts of the city such as El Poblado, which ultimately reached the city of Envigado, while the working class population of Medellín reached cities to the north (Bello) and the southwest (Itagüí).
