Final answer:
The period between 1776 and 1791 in the USA was marked by the Declaration of Independence, the Revolutionary War, the Articles of Confederation, the drafting of the US Constitution, and the ratification of the Bill of Rights.
Step-by-step explanation:
Between 1776 and 1791, the United States experienced pivotal moments shaping its early existence. On July 4, 1776, the Declaration of Independence was proclaimed, asserting American sovereignty from British rule, followed by the Revolutionary War, where American resilience was tested against the British military. The loosely structured Articles of Confederation, ratified in 1781, soon revealed weaknesses, lacking federal authority to impose taxes or regulate interstate commerce.
This necessitated the crafting of the Constitution of the United States in 1787, which redistributed power to ensure a capable central government, and upon its ratification in 1789, it superseded the Articles. Subsequently, the first ten amendments, known as the Bill of Rights, were introduced in 1789 and ratified in 1791, embodying fundamental liberties and legal protections.
