How did popular uprising contribute to the French Revolution?

In my humble opinion, it was hunger. Hunger led to the "popular uprising." Marie Antoinette had a hearty appetite for jewels and gambling and she had little real knowledge of the people she and her husband ruled. Taxation of the poor working class led to further and further desolation. The people were taxed to support the nobility who supported the King and Queen. Remember-these rulers honestly thought they were given the right to rule by God. So who would question a person that was deemed to be God given? For the fearful, uneducated, superstitious peasant it would be next to being blasphemous to not give to the Royalty. So-it was whether to save your soul or starve. In the end, starvation won the war against those who might or might not be next to God.
