Final answer:
Pinckney's Treaty came about due to concerns over the relationship between the United States and Great Britain. The treaty, negotiated with Spain, allowed American farmers to use the Spanish port of New Orleans which significantly improved American commerce.
Step-by-step explanation:
The background behind Pinckney's Treaty originated from concerns over the relationship between the United States and Great Britain, as indicated by Jay's Treaty in 1794. Seeing this, Spain decided to negotiate their own treaty with the United States. Pinckney's Treaty, named after the U.S. representative Thomas Pinckney, addressed land and navigation disputes along the Mississippi River and primarily allowed American farmers increased use of the Spanish port of New Orleans for their goods. This benefit significantly improved commerce within America as products could be transported from the Ohio and Mississippi Rivers to East Coast markets. Pinckney's Treaty therefore played a significant part in the expansion and economic development of the United States.
