Economics in Colonial America During the 1500's to 1800's, the strength and stature of a country depended upon its political power, which can be traced to how self-sufficient it was. Striving to be self-sufficient was what nations sought after; dependency was not a characteristic of a powerful nation. Raw materials were the most required item to strengthen the central government, and deter interactions, such as trade with other nations. The first country to introduce mercantilism in America was Spain. The spanish american colonies were not allowed to trade directly with Europe.
