How was Naples different from the other Italian city-states?
A. It did not focus on agriculture.
B. It rejected feudalism together.
C. It did not have a large professional middle class.
D. It was protected from foreign influence.
Answer: C. It did not have a large professional middle class.
Step-by-step explanation:
Naples was the fifth city-state, and the farthest south.
Despite its farmland being poor, Naples´ economy was mostly based on agriculture and was still under the rule of a few extremely wealthy nobles in a feudal system, while most of the farmers experienced atrocious poverty.
Most of Naples´ finance and commerce was controlled by cities such as Florence, therefore Naples didn´t have a large professional middle class as the other city-states.
