Meeting of The Estates General
I called this meeting to discuss the financial issues France has. Let's vote on how we should handle this. Each estate will vote as a body.
I will hold a meeting with others from all three the estates
That is far from fair, you will both out vote my estate.

The King soon found out of this assembly and did not condone it and closed the building where the national assembly was held.
We can never separate and need to vow to reassemble wherever circumstances require, til the constitution of the kingdom is established

A mob stormed the Bastille looking for gunpowder and weapons, by overwhelming the guards and gained control of the building. Multiple attackers killed the commander and clueless guards. they mob later walked around the town with the heads of the men they kills on sticks.
I AM OVERWHEMED!
A mob of women marched on versailles demanding their family get breed. Which the king then agreed and gave the crowed breed, although it was much deeper than just breed this was a step to women equality and getting their rights.
The king was walking quickly to the guillotine and was executed. Nine months later, Marie Antoinette was convicted of treason by a tribunal, and on October 16 she followed her husband to the guillotine.
The Reign of Terror
The radicals arrested and executed anyone who they found suspicious who wasn't loyal to the revolution. This was a step of toward democracy because knowledge was more important than family status for important positions.
