The Constitutional convention of 1787 in Philadelphia was typical of this situation. Every problem found divergent interests and opinions; every solution was effected by compromise. [63]There was state jealousy of all central authority; the opposition between large and small states; that between the industries of the north and the agriculture of the south; the slave trade, with its complex of moral and economic problems; the sectionalism of the settled east and the frontier west; the protection of the property-holding class and the satisfaction of the radicals with their demand for liberty and equality. Every one of these conflicts had to be settled if possible, or at least (as with slavery) brought to a temporary status to avoid sharp struggle. There were, of course, certain unifying factors. The majority of the settlers were English, and most of these Protestants. The non-English speaking elements were very largely of Teutonic blood and Protestant religion also. There was a common political experience, and a democratic urge typical of the frontier. Most important of all, there was an eight-year war fought together against a common enemy and under the same Commander-in-Chief. The American government, then, with its new Constitution, was not a simple unity from the outset. It was rather a highly complex unity, containing within itself many minor groups, many different viewpoints, and many integrations of the sub-group for the benefit of the nation as a whole. 2.
