Final answer:
The Treaty of Rome in 1957 was indeed the first step towards the creation of the EU, setting the stage for economic integration which eventually led to the establishment of the EU under the Maastricht Treaty in 1993.
Step-by-step explanation:
The statement that the Treaty of Rome in 1957 was the first step in the creation of the European Union (EU) is indeed true. The Treaty of Rome, signed by Belgium, Germany, France, Italy, Luxembourg, and the Netherlands, established the European Economic Community (EEC), which was a significant move towards economic integration in Europe. This integration effort started with the creation of a free trade association and evolved into what is now known as the full economic union of the EU. Notably, the EU was formally established later, under the Maastricht Treaty in 1993, which also introduced a common currency, the euro, and a commitment to common security and foreign policies. The efforts to unify Europe, thus, began much earlier than the official formation of the EU, with treaties like the Treaty of Rome laying the necessary groundwork.
