Were the changes in the french government inevitable ?

Answer 1

Be more specific. There have been several major changes in the French Government.

If you are talking about the French Revolution, then yes. The monarchy had overspent themselves into bankruptcy. The tax burden was on the poor and middle class. They had not adopted modern banking as England had done. When the King called the Estates General for the first time in almost 200 years, he couldn't control the chain of events.
