Answer:
Like the earlier distinction between “origins” and “causes,” the Revolution also had short- and long-term consequences. Perhaps the most important immediate consequence of declaring independence was the creation of state constitutions in 1776 and 1777. The Revolution also unleashed powerful political, social, and economic forces that would transform the post-Revolution politics and society, including increased participation in politics and governance, the legal institutionalization of religious toleration, and the growth and diffusion of the population. The Revolution also had significant short-term effects on the lives of women in the new United States of America. In the long-term, the Revolution would also have significant effects on the lives of slaves and free blacks as well as the institution of slavery itself. It also affected Native Americans by opening up western settlement and creating governments hostile to their territorial claims. Even more broadly, the Revolution ended the mercantilist economy, opening new opportunities in trade and manufacturing.
The new states drafted written constitutions, which, at the time, was an important innovation from the traditionally unwritten British Constitution. Most created weak governors and strong legislatures with regular elections and moderately increased the size of the electorate. A number of states followed the example of Virginia, which included a declaration or “bill” of rights in their constitution designed to protect the rights of individuals and circumscribe the prerogative of the government. Pennsylvania’s first state constitution was the most radical and democratic. They created a unicameral legislature and an Executive Council but no genuine executive. All free men could vote, including those who did not own property. Massachusetts’ constitution, passed in 1780, was less democratic but underwent a more popular process of ratification. In the fall of 1779, each town sent delegates––312 in all––to a constitutional convention in Cambridge. Town meetings debated the constitution draft and offered suggestions. Anticipating the later federal constitution, Massachusetts established a three-branch government based on checks and balances between the branches. Unlike some other states, it also offered the executive veto power over legislation. 1776 was the year of independence, but it was also the beginning of an unprecedented period of constitution-making and state building.
