Final answer:
The statement that is NOT true of Jay's Treaty is D. The Republican Party supported it, as the Democratic-Republicans strongly opposed the treaty, which they saw as favoring British interests over those of the French.
Step-by-step explanation:
Which of the following is NOT true of Jay's Treaty? The answer is D. The Republican Party supported it. Jay's Treaty, ratified by the Senate in 1795, resulted in several outcomes, including the withdrawal of British troops from forts in the Great Lakes region, the granting of American ships the right to trade in the West Indies, and it also led to an improvement of trade relations with Great Britain. However, this treaty was highly controversial and faced significant opposition, particularly from the Democratic-Republican Party, which believed the treaty favored British interests and betrayed the French, America’s ally during the Revolutionary War.
The opposition to Jay's Treaty helped to cement the differences between the fledgling parties, contributing to the solidification of the First Party System in the United States. The treaty, in fact, was seen by many in the Democratic-Republican Party as a symbol of Federalist alignment with British aristocracy and monarchical principles.
