By the 1570's, Potosí, and its silver, had become the hub of a commodity revolution that reorganized Peru's peoples and landscapes to serve capital and empire. This was a decisive moment in the world ecological revolution of the long seventeenth century. Primitive accumulation in Peru was particularly successful: the mita's spatial program enabled the colonial state to marshal a huge supply of low-cost and tractable labor in the midst of sustained demographic contraction. The relatively centralized character of Peru's mining frontier facilitated imperial control in a way the more dispersed silver frontiers of New Spain did not. Historical capitalism has sustained itself on the basis of exploiting, and thereby undermining, a vast web of socio-ecological relations. As may be observed in colonial Peru, the commodity frontier strategy effected both the destruction and creation of premodern socio-ecological arrangements.
