The French Revolution lasted for about ten years, in which the public rebelled against the government when they decided to overthrow the King and Queen. The whole thing ended with the public beheading of both King Louis XVI and Marie Antoinette.
In 1791, congress passed a tax on whiskey in order to pay off the federal debt. Many citizens where angered by this new tax, claiming government had no right to put a tax on what they had made on their own. At first protestants where peaceful, but eventually things got out of hand. George Washington then made up an army of 13,000 men to confront the protestants and solve the issue once and for all.
When the British and French went to war, the french asked the U.S. for help. George Washington wanted nothing to do with the war, and so declared it in this proclamation without an approval from congress.
This treaty resolved issues between America and Britain that if not, might have possibly led to war. It obliged the British to pay for damage done to American ships, and leave their forts on Northwestern territory. Many American citizens where upset, for they didn't think they where punished for a large part of what they had done.
Native American leaders signed the treaty, stating that they'd let the Americans take over most of their land after five years of fighting due to U.S. expansion.
In 1784, Spain controlled the port of New Orleans, and closed it to the U.S., affecting trade. This hurt the American economy, due to the fact that much of American goods had to pass through the New Orleans port. Pinckney's Treaty solved border issues, thus reopening the port once again.
