Long- Long of wars have drained the wealth.
For maintainance of the court of Versilies.
For maintainance of army.That's the reason why King Louis XVI has to raise taxes.

Louis XVI, the King of France, was compelled to raise taxes to meet the growing financial crisis in the country. There were several reasons that led to this decision.

1. Costly Wars: France had been involved in many costly wars, including the Seven Years War and the American Revolutionary War. These wars had depleted the country's finances and left France in a state of economic crisis.

2. Extravagant Court: The French royal court was known for its extravagance, and Louis XVI was no exception. He spent heavily on building grand palaces, hosting lavish parties and maintaining a large retinue of courtiers. These expenses put a heavy strain on the royal treasury.

3. Poor Tax Collection System: The tax collection system in France was outdated and inefficient. The nobility and the clergy were exempt from paying taxes, and the burden of taxation fell on the common people. This led to widespread resentment and protests against the government.

To address these issues, Louis XVI was forced to raise taxes. However, this move only worsened the situation as it further increased the burden on the common people. The rising discontent eventually led to the French Revolution in 1789, which saw the overthrow of the monarchy and the establishment of a republic.
