Explanation:

However, this extension of citizenship to the people in the conquered territories helped them maintain peace and spread the idea of the shared identity of everyone. People who were conquered would be encouraged to assimilate and feel like the citizens of Rome, which could make them more content and prone to sharing ideas of Roman politics.
