3rd Estate breaks tradition
The estates haven't voted in 175 years and it was always in the 1st and 2nd estates favour. The 3rd estate had more representatives but hardly any power, so the higher estates teamed up and out voted the 3rd. They released they need to change the voting and built a new constitution called the National Assembly.
Pressured by debt
The government now had no power over the estates and pressured Louis to sign the agreement and retire is old one. Louis had been slipping since he paid to help other county's fight wars, he couldn't even feed his people. Louis was weak and need to regain power, he was struggling to hold his authority figure.

step closer to end the revolution and monarchy. The demand rights and freedom, this showed that there voices were being heard.
