1.	How did the organisation named ‘ZoUverin’ prove useful in the political unifiction of Germany?
Answer» The organisation named Zollverin was very helpful in the political unification of Germany. In 1818, Prussia made a treaty named ‘octroi union’ with the small states of Schwarzburg and Sonderschossan, that was named Zollverin. By this treaty, goods began to be transported freely between these states. Also levy of octroi between them was abolished that helped trade develop considerably. Initially, other German states did not take interest in this economic cooperation, but gradually, they realised the importance of this economic policy, and forgetting mutual discords, almost all states joined this union by 1834. In this way, this economic strategy ended regional feelings and strengthened Imperialist leadership
