What was the purpose of the cotton gin popularized by Eli Whitney?

The cotton gin revolutionized agriculture. It also made possible the cotton economy of the American South, perpetuating and increasing the practice of slavery upon which the agricultural system depended. In 1798, Whitney, who had not seen much profit from his epochal machine, launched a new venture: arms manufacturing.

France played a key role in the american revolutionary war (american war of independence; 1775–1783). motivated by the ideals of the new nation which were inspired by the french enlightenment, as well as its long-term rivalry with britain and so as to avenge their territorial losses during the french and indian war, france secretly began sending supplies to the americans in 1775.
