An important goal of the Bourbon Reforms was to increase legal, registered trade with Spanish America in order to collect more tax revenue for the Crown, an aim that was frequently undercut both by the prevalence of contraband and the increasing presence of foreign merchants. One strategy to diminish this trade in contraband was the relocation in 1717 of the Casa de la Contratación. This was the House of Trade which oversaw Spanish trade with its colonies, and was moved from Seville, where traders frequently dealt in contraband, to Cádiz. However, this effort did not prove highly effective, as the trade of contraband simply moved with the Casa de la Contratación to Cádiz.
