The founding generation had many reasons for wanting to form a ‘more perfect union.’
Having fought a long bloody war for freedom, many recognized the advantages the union offered in terms of mutual defense. At the signing of the Declaration of Independence, Benjamin Franklin famously quipped, “We must all hang together, or assuredly we shall all hang separately.”
Along those same lines, many founders believed the states would fare better in international relations interacting with other world powers as a united entity. Even operating as a union, the Americans were at a significant power disadvantage when dealing with England, France, Spain and other European powers. Separately, they would have virtually no power.
Then there were the economic advantages of a union. In much the same way unity increased diplomatic power, it also increased the America’s economic power.
Alexander Hamilton even argued that a single general government would conserve American resources.Details
