Technology and Society: The Impact of Gold Mining on the Institution of Slavery in Portuguese America
Published online by Cambridge University Press: 11 May 2010
Abstract
This article examines the impact of gold mining on slavery in colonial Brazil. Crown policies, economic pressures, and gold's role as an instrument for social mobility had demographic repercussions—affecting sexual imbalance, the ratio of slaves to freedmen, the availability and distribution of labor. Economic factors determined ethnic origins, slave trade patterns, and the assimilative capability of blacks as illustrated by the slave family. Differences between slavery in mining and plantation societies are emphasized. The transfer of technical skills is signalled as a major African contribution to the New World. The article concludes by assessing the psychological and administrative impact of a black majority.

Protests by the council of Rio de Janeiro that leading buyers conducted all transactions within the customshouse and enjoyed a virtual monopoly on sales, resulting in higher prices, were rejected by royal advisers in the interests of the overall trade.

In a letter of 7 May 1751 to the king, the Council of Vila Rica provided an insight into prevailing values in the mining region: “… grande numero de escravos que são os bens das Minas sendo certo que muyta parte destes estão devendo os mesmos escravos que possuem, parecendo no exterior rico o que na realidade he pobre, e vivendo como pobres muytos que na realidade são ricos…” APMCMOP, Vol. 60, fols. 54v-59v.
8 An alvará (1721), described by the governor as “the most blessed law passed for the mining areas,” ordered that all slaves to be sold to satisfy creditors should be valued and creditors obliged to accept them at a just price.

14 On the 1720 decrease, see APMSG, Vol. 11, fols. 244v-47v, 287v-88v. The 1723 figure is based on Council of Vila Rica to king, 22 December 1723, APMCMOP, Vol. 9, fols. 9v-10v. A “head count” in 1728, for a “voluntary” contribution to royal marriages, placed the slave population at 52, 348. APMSG, Vol. 24, fols. 4–7; APMDF, Vol. 47, fols. 64v-66v. Figures for 1716–20 are based on capitation records (APMSG, Vol. 11, fols. 275–76, 280–81, 287v-88v): allowance must be made for discrepancies in the counting of slaves belonging to clerics. Overall estimates are based on Goulart, Escraviddo, pp. 139–45. His figure for Sahará in 1723 (9,488) should be modified upwards and based on the 1720 capitation (8,031) instead of that for 1718 (which reads 5,771 and not 5,721). Ibid., p. 140, n. 28. See also APMSG, Vol. 11, fols. 280–81; Vol. 13, fols. 25v-27, and APMDF, Vol. 44, fols. 13v-15. This brings his estimate of 50,000 more in line with the 53,000 reported above.
