The French Revolution was a period of political upheaval in France which lasted from 1789 to 1799. I personally think it ended in 1802, when the War of the Second Coalition ended. The revolution started out as monarchy, and it ended as a monarchy.
The War of the First Coalition is fought between the French Republic (Kingdom of France) and Great Britain, Holy Roman Empire, Spain, etc.
Same thing with the War of the Second Coalition.
In 1801, Great Britain changed into the United Kingdom after incorporating Ireland
