Answer: The three things that left France´s government in debt before the revolution were:
1- France´s involvement in the Seven Year´s war (1756-1763)
2- France´s participation in the American Revolution of 1775-1783 and also the costs of having a big army and navy to mantain.
3. The costs related to the King Louis XVI´s extravagant palace at Versailles and the superficial spending of the queen, Marie-Antoinette
Explanation: The involvement in wars and the extravagant spendings of the kings were the main factors that led France to the Revolution. Since if it wasn´t for these financial irresponsabilities, France would still have been prosperous at the time.
