An entrepreneurial class established in Rio de Janeiro during the mining surge was able to induce the government to help create basic conditions for the expansion of coffee, such as removing transportation and labor bottlenecks. From the area near Rio de Janeiro, coffee production moved along the Paraíba Valley toward São Paulo State, which later became Brazil's largest exporting region.

However, it soon became necessary to ease two basic constraints: the lack of transportation and the shortage of labor.
