Britain's Navigation Acts prevented New England from trading its valuable commodities with other European nations. However, timber was excluded from the Navigation Acts allowing the colonies to export vast quantities of wood commodities to nations otherwise beholden to British duties. Oak staves for wine barrels, along with building timber, white pine boards, and cedars shingles were traded to Spain, Portugal, the Canary Islands, the Azores, and Madeira. In addition, inter-colonial trade was unrestricted, allowing for the development of a major trade relationship with British Barbados.
