Final answer:
The role of the people in the unification campaign in Italy and Germany was significant and played a crucial role in the success of the movements.
Step-by-step explanation:
The role of the people during the unification campaign in Germany and Italy was significant. In Italy, the nationalist movement led by Giuseppe Mazzini emphasized national unity as a means of promoting popular sovereignty. On the other hand, in Germany, the unification campaign led by Otto von Bismarck focused on fortifying the strength and interests of Protestant Prussia. The people played a crucial role in supporting these movements and their efforts ultimately led to the unification of Italy and Germany.
