Answer:
In order to raise their voice against the injustice done to them by the feudal system, the third estate formed the national assembly.
Explanation:
- The third estate was convinced beyond doubt that the other two legions made up of the clergies and the nobles would never take decisions in favor of the common people.
- They believed that for the good of the commons, the administration would be needed to be taken into their own hands.
- Hence, they formed the National Assembly in order to establish their might in the society dominated by clergies and nobles.
