Cause: Drought
The drought in France in the spring of 1788. At that time, France had not recovered from the drought three years ago. The last drought resulted in inadequate feed and large-scale slaughter of livestock, resulting in a large number of idle farmland in France with livestock excrement as the main fertilizer due to insufficient fertility.（Drought led to food shortage, which was the fuse of the French Revolution.）

Hail
Hail destroyed farmland, causing a lot of loss of income. The extreme cold in France in the winter of the same year led to a sharp rise in bread prices, increased morbidity and mortality, massive famine and widespread malnutrition on the eve of the French Revolution. And the government does not have enough transportation capacity to transport food to the disaster areas（Continuous natural disasters and government failure accelerated the revolution.）

A meeting of dignitaries
Louis XVI held a meeting of dignitaries. The participants were all aristocrats. The aristocracy wishes to carry out constitutional reform, and any tax increase must be approved by a three-level conference. The king may not arbitrarily arrest or detain the people, and plans to hold a three-level conference in May 1789.(The third-level meeting completely disappointed the people at the bottom of the hierarchy.)

Third-level meetings in Versailles
Third-level meetings are held in Versailles. The basic tactic of third-level meetings is that all resolutions must be decided by three-level open discussions. Therefore, they require that the identification of delegates must be carried out in public, not only in their respective hierarchical groups. The clergy's claim that it would take more time to complete was rebutted by the public.（People have a little power, but they can't get real equality.）

National council
The National Assembly is a parliament that serves not the country but the people. They invited two other classes to participate, and in the indoor tennis court they issued the Tennis Court Declaration, declaring that the National Assembly would remain until the French Constitution was established..(The people need a leader to lead them against the other two classes.)

Capture Bastille Prison
The rebels focused on weapons and ammunition stockpiles in the Bastille prison. The Bastille was therefore regarded as a symbol of the French feudal system. After hours of fighting, the Bastille was captured that afternoon.（Bastille prison is a symbol of feudal system. The capture of Bastille prison is a great inspiration to the people.）

Flag of France
The King visited Paris and on July 17 agreed to confirm the national flag as a blue, white and red tricolor flag, as well as the slogans "Long live the country" and "Long live the king". Conservative aristocrats were very dissatisfied with the Royal family's behaviour, and some people who had doubts about the political situation began to exile.（Similarly, changes in the flag have made the situation more chaotic.）

Abolish the feudal system
The National Constitutional Assembly adopted a resolution to abolish the feudal system, which wiped out the second level of feudal sovereignty and the first level of the power to collect taxes. Thus nobles and priests lose their privileges in towns, cities, provinces and so on.（The collapse of feudal system and the fall of noble priests)

Déclaration des Droits de l'Homme et du Citoyen
The National Constituent Assembly issued the Declaration of Human Rights. This declaration not only has the constitutional effect, but also is more important for the declaration of the principles of the National Constituent Assembly. It declared the National Constitutional Assembly to be the organ for drafting the new constitution.(It is an important historical node that the people at the bottom have finally acquired human rights.)

Women's movement
A procession of women began to gather in the Paris market and March to the city hall. Women believe that government officials are responsible for the severe economic situation, especially the food shortage. The Royal Family and the Government were asked to move to Paris to show their sincerity in resolving the widespread poverty in French society at that time.(Women declare their sovereignty and prove equality by action.)
