Porfirio Diaz was president of Mexico from 1884 to 1911, This was a time of great economic growth for Mexico, as the regime opened its doors to foreign investment, particularly in the mining sector. However, Diaz's policies promoted a strong centralized government, which would lead to an unequal focus on certain regions and economic activities of the country, leaving others exposed to impoverishment. The expropriation of peasants lands in favor of big enterprises enraged rural populations. Inequality among the regions and societies of urbanized areas was becoming more evident. This led to a series of manifestations against the government that would eventually lead to the end of the regime.
