The Montagnards/Jacobins, The Plain, and Girodins are all meeting to talk about their future plans.
Execution of the King
The Girodins don't believe it is right to kill the king, but the Montagnards/Jacobins think they don't care enough. The Plain supported the Girodins at first but then sided with the Montagnards/Jacobins.
Committee of Public Safety
Maximilien Robespierre, a Montagnard/Jacobin, has taken control of the National Convention and decided that unless you are 100% with him you aren't loyal to the cause.
This isn't that great
Honestly, things were better with a king
The king was placed on trial. The Girondins hoped it would never happen but eventually, it did. He was sentenced to die the next morning and the streets were quiet as he was put into the guillotine
After taking complete control, Maximilien Robespierre created the Committee of Public Safety. This was created to manage the country's defenses, they drafted every man 18-45 into the military.
The people began to speak out and say that their situation wasn't much better. They realized their leader wasn't great and it was better with a king. They just wanted things to be back to normal.
