Final answer:
An economic agreement unifies people through mutual economic interests and cooperation and by promoting peace and economic prosperity, as evidenced by the success of the European Union, which established a common currency and removed trade barriers.
Step-by-step explanation:
An economic agreement can unify people primarily through the following ways:
- Through mutual economic interests and cooperation, which can lead nations to work together towards common goals, resulting in strengthened relationships and shared success.
- By working to maintain peace and economic prosperity in the world, economic unions can dissuade the occurrence of conflicts and wars, as well-functioning economic partnerships can make the prospect of aggression less appealing.
For example, the European Union (EU) is a regional trading agreement that became a full economic union with the goal of ensuring peace and fostering economic growth through collaboration. It promotes free movement of goods, labor, and capital and has even established a common currency, the euro, to ease trade and economic exchange among its member states.
