to what extent would it be accurate to say that the new england ,middke and southern colonies had merged to create a single american society by the oubreak of the revolution?

In my opinion, from everything I've read, it would not be accurate. There were many colonists who did not believe there should be a revolution or a separate country.

Read the first two paragraphs carefully.

Another thing to think about is how long it took, after the war was won, to come up with the Constitution that we still have today.

then

This is a difficult question to answer.

The reason for the difficulty is that there is no single correct or incorrect answer and the conclusion is almost immaterial.

There were many examples at the beginning and during the revolution indicating that there was not a single American Society. Begin by reading Sections I and III of background to the american revolution lecture outline http://www.u-s-history.com/pages/h789.html and then later why it succeeded.

There were many colonists who were against the Revolution. One of our founding fathers said that 1/3 were for independence, 1/3 were against independence and 1/3 did not care. Read about the Loyalists (those who were loyal to England) at:

An interesting sidelight of the American Revolution was about George Washington and his glasses.

Think also about the philosophy of natural rights, the social contract and the strong theoretical background
leading to the revolution and the uniting of the people in all sections in what we regarded as the evils of British colonialism.

Yet, we did of course win our independence. One of the major units that you will shortly deal with is how nationalism grew in the new nation.

Please also remember that this was a difficult and world wide important war that not only affected us but Europe and other nations as well.

In History it is very often not the conclusion that you reach but the way that you marshall evidence to support your opinion.

To answer the question about the extent to which the New England, Middle, and Southern colonies had merged to create a single American society by the outbreak of the revolution, it is important to consider multiple factors and perspectives.

First, it is crucial to acknowledge that there were significant differences among the colonies in terms of culture, economy, and social structure. The New England colonies, for example, were known for their Puritan religious beliefs and strong emphasis on education, while the Southern colonies relied heavily on agriculture, particularly the plantation system and the institution of slavery. The Middle colonies had a more diverse population and were known for their religious tolerance and trade.

To evaluate the extent of merging, it is noteworthy that there were colonists who did not support the revolution or the idea of a separate American society. Some colonists remained loyal to Britain and actively resisted the revolution. These Loyalists, also known as Tories, faced persecution and even had to flee to Britain or other British colonies. This division within the colonies indicates that a single American society had not fully formed by the outbreak of the revolution.

Furthermore, it is important to consider the post-war period, during which the Articles of Confederation were established as the first governing document of the United States. However, the weaknesses of the Articles, such as a lack of unified authority and economic regulation, led to the eventual creation of the U.S. Constitution. This process demonstrates that it took time and negotiation to establish a more unified and cohesive American society.

In conclusion, while the American Revolution was a significant milestone in the path towards creating a single American society, it is not accurate to claim that such a society had fully merged by the outbreak of the revolution. Differences among the colonies, the presence of Loyalists, and the subsequent challenges in forming a cohesive government all indicate that the process of creating a single American society was ongoing.
