Why were there so many revolutions in France in the 19th century?

The first revolution in France in the 19th century was the formation of the empire of Napoleon I in 1804 due to the increase in the authority of the commander. It would have lasted longer if it had not been stopped by a coalition of European countries in 1815. A monarchy was established, but it did not inspire confidence in the population. Therefore, in 1848-1849. there was a February republic. However, the reaction turned out to be too strong and the Bonapartists came to power again, placing Napoleon III on the throne. His surrender in the Franco-Prussian War caused an instant drop in authority among the citizens. Therefore, his power was overthrown and the Fourth Republic appeared.
