The English replaced France and Spain as the single-most influential political and economic power in North America during the first three quarters of the eighteenth century. During that time, the North American part of Spanish Empire covered an immense but sparsely populated and economically inactive territory. The colonies consisted of several small and isolated urban clusters, mostly under the control of Indian. The colonies' dependence on trade and extraction of Indian labor, and failure to attract settlers made the colony impoverish. Florida remained a stagnant military outpost, and others were dotted by a small number of mission outposts that attempted to convert Indian. French colonies, in contrast, was able to rival the British ones. It possessed a expanding colony in Canada and continued into Mississippi River Valley. Prosperous farming communities with a vibrant and established social life developed in colonies. Though populated, the colonies were still dwarfed by the British ones, due to the dominant prejudice against emigration. Yet the French still posed a threat to British in military and trading power. However, after the power struggle in the Seven Years' War, the British obtained Canada from French and Florida from Spain, and became the dominant power in North America.
The US government had imposed tariff policies that set a higher price on imported (foreign) manufactured goods. Because the South was an agricultural economy, it either had to ship down form the North or import from other countries most of the finished goods it consumed. Either option increased the cost of goods for Southerners over the prices paid by Northerners. Because the North was a largely industrial economy, and because raw materials imported for manufacturing were not subject to tariffs, the North faced no such burden. Additionally, because there was no income tax at this time, federal gov't revenue depended largely on tariff revenue -- which meant it was paid disproportionately by the South. This revenue was spent on railroads in the North and in other ways that unfairly benefitted the North while largely ignoring infrastructure and development in the South. South Carolina threatened secession as far back as 1828 over the unfair burden of the protective tariffs.
