Why was France almost bankrupt?

France was almost bankrupt in the late 18th century primarily due to its involvement in expensive wars, including the American Revolutionary War, which strained the national finances. Additionally, the country's tax system was inefficient and disproportionately burdened the lower classes, while the nobility and clergy were largely exempt from taxes. This financial crisis was compounded by poor harvests and economic mismanagement, leading to widespread discontent and ultimately contributing to the outbreak of the French Revolution in 1789.
