production with governmental aid, adopting technical and technological innovations. In the north and northeast of the country, great centers called engenhos centrais ("central engines") were established for the processing of sugar cane, which revolutionized the traditional economy. These plants came to occupy the place of the old factories of sugar cane that dated from the colonial period, effectively industrializing the sector. At the coffee plantation regions the producers made the transition from the enslaved man power to the paid one, with the absorption of foreign immigrants who arrived at the thousands each year and of former slaves. The benefits were many, but the main one was the reduction of the production cost, as the sustenance of slaves revealed that were more onerous than the payment of wages of free workers. The province of São Paulo was the one that better reached success as it went from the old slavery economic system to the modern capitalist economic system. The province of Rio de Janeiro, however, revealed itself incapable of assimilating the new trends of the market, as it preferred to keep the use of enslaved man power until the end, which would eventually cause its economic collapse at the end of the Empire. The imperial government was not limited to facilitate the credit for the purchase of modern equipment or the arrival of immigrants, but also diminished taxes to collaborate with the effort of modernization of the country's agricultural production. One of these measures occurred in 1874 when the Rio Branco cabinet fixed at 40% the custom house tax for all the imported goods (which would come to stimulate the national industry) at the same time as it created taxes for related importations of plants, seeds, roots, bulbs and mechanical devices with the intention of developing the agriculture. Industry Origins Brazilian industry has its earliest origin in workshops dating from the beginning of the 19th century. Most of the country's industrial establishments appeared in the Brazilian southeast (mainly in the provinces of Rio de Janeiro, Minas Gerais and, later, São Paulo), and, according to the Commerce, Agriculture, Factories and Navigation Joint, 77 establishments registered between 1808 and 1840 were classified as “factories” or “manufacturers”. However, most, about 56 establishments, would be considered workshops by today's standards, directed toward the production of soap and candles of tallow, snuff tobacco, spinning and weaving, foods, melting of iron and metals, wool and silk, amongst
