[Ernst Hasenclever in Gongo-Soco: English exploitation of the gold mines in the state of Minas Gerais in the nineteenth century].

Based on the report of Ernst Hasenclever on his visit to the Gong-Soco gold mine in 1839, this article seeks to understand the labor and administrative organizational system implemented by the English gold mining companies in Minas Gerais, especially in the second half of the nineteenth century at a time when the slave-based system was in its final stages. Our objective is to show the continuity of the administrative system and the use of slave labor by the English companies from the 1830s until the end of the century, despite the pressure applied by England against the transatlantic slave trade and the prohibition of Her Majesty's subjects to own slaves anywhere in the world.
