Superbus used violence to get what he wanted. Brutus and the rest of Rome saw that Superbus must be defeated.
Please, I never meant too!
Superbus, you have caused to much violence. Be gone with you.
Brutus rounded up citizens and overthrew Superbus. After Superbus was not a threat anymore, the Romans had seen the last of monarchy.
After Superbus ruled, the Romans were reminded of how risky it is to have a king. It is risky because the king has power over all people, no the king has the final voice in decisions. Brutus decided to change this, so he created the Roman Republic.
What if we create a Republic where more people have a voice in the government.
We, Patricians, have control over everything, including you filthy Plebeians. You guys have no voice in the government.
In the Roman Republic, the Senate and everyone who had a voice in the government was Patricians (wealthy citizens). Plebeians had no voice and they hated this, so they decided to go on strike.
Its super unfair. We should go on strike.
The Plebeians went on strike by camping out on a hill until the Patricians gave them equal rights. Since Plebeians made all of the food, the Patricians wouldn't be able to survive, so they created Tribunes and The Council of Plebs.
I speak for all of the Plebeians, we will not come down until we have equal rights with the Patricians.
Fine, you can have equal rights. We will create Tribunes and the Council of Plebs
These are the Tribunes. The Tribunes are Plebeians that are able to speak to the senate and they could veto/overrule laws made by the Senate.
This is the Council of Plebs. They are a council made up of Plebeians that were able to make laws that only applied to the Plebeians.
