Establishment of new viceroyalties also revealed a new revelation on the part of the Spanish crown: that there are huge circuits of illicit trade in Spanish America, and that it is in the best interest of the crown to incorporate these circuits of trade into the existing infrastructure. This way, the crown was now able to collect tax revenues from those circuits of trade that had previously eluded it. Although some analyze the Bourbon reforms by arguing that the purpose of the reform was to eliminate contraband trade and other illicit circuits of trade, a closer analysis of the material evidence available indicates that many of these circuits did not disappear, but were simply incorporated.
