A) ¿Qué sectores sociales y económicos apoyaban a Rosas?

The regime of Rosas in Buenos Aires enjoyed far broader support than any of its predecessors. Special interest groups, landholders, and export-import merchants  all fell behind the new governor. Practically all the influential sectors in the province identified Rosas’s triumph with their own best interests. Argentina’s society and economy underwent considerable changes in the 30 years after 1820. Buenos Aires was the province best adapted to the new era of free trade, exporting cattle products in return for consumer goods from overseas. The interior provinces adjusted slowly, replacing their traditional markets in Upper Peru with new ones in Chile, where a great expansion of the mining industry was taking place. The coastal provinces fared better, although their livestock industry suffered from the effects of the civil war. For Santa Fe, moderate prosperity returned in the 1830s, and a similar trend began in Entre Ríos and Corrientes provinces in the 1840s.
