Geography and climate, institutional developments, religion and race, and other factors beyond our ken, may have made the separation inevitable. Only the immediate causes, however, can be studied in these documents.

Then came an attempt to check this evolution; to create new institutional bonds between the colonies and Great Britain, and to strengthen such as existed. It was a part of the struggle between centralization and localism which runs through all modern history; and not the least interesting phase were the attempted solutions through federalism-- unsuccessful in 1774-5, successful on a smaller scale in 1787-8.
