Final answer:
The claim that the U.S. system of government is based on the Algonquian tribe is false; instead, the Founding Fathers were notably influenced by the Iroquois Confederacy and European Enlightenment thinkers. Additionally, not all tribes of the Iroquois Confederacy maintained neutrality in the Revolutionary War; some sided with different factions, resulting in internal division.
Step-by-step explanation:
The question regarding the U.S. system of government being based on the Algonquian tribe is false. It is well-documented that while the Founding Fathers, such as George Washington and Benjamin Franklin, were inspired by various sources for the U.S. Constitution, a notable influence was the political system of the Iroquois Confederacy. The confederation of the original Thirteen Colonies and many democratic principles within the Constitution are attributed to the Iroquois influence. However, it's important to recognize that the Founding Fathers were also heavily influenced by European Enlightenment thinkers like John Locke, with the Declaration of Independence drawing upon Locke's theories, and the Baron de Montesquieu's ideas on the separation of powers within a government.
Regarding the Iroquois Confederacy during the Revolutionary War, the statement that all tribes maintained neutrality is false. There were varying alliances and some members of the Iroquois Confederacy sided with the British, while others supported the American cause, which led to internal divisions and conflict within the Confederacy.
