Which contributed most o the crisis of 1789 in France incompetent king an ambitious nobilityor poor harvest?

The crisis of 1789 in France was primarily driven by a combination of factors, with poor harvests playing a significant role. The failing crops led to widespread famine and economic hardship among the peasantry, which exacerbated social tensions. While the incompetence of King Louis XVI and the ambitions of the nobility contributed to the unrest, it was the immediate suffering of the populace due to food shortages that ultimately ignited the revolution. Thus, the poor harvests can be seen as the most direct catalyst for the crisis.
