Final answer:
The ultimate objective of the European Union is to eliminate trade barriers and foster economic integration among member countries, promoting peace and prosperity through closer ties and shared policies.
Step-by-step explanation:
The ultimate objective of the European Union (EU) is to eliminate barriers to the mobility of goods, labor, and capital across Europe. After World War II, European nations sought to tie their economies together, beginning with a free trade association and eventually forming the EU, which aims to foster closer economic ties to avoid conflict and promote prosperity. The introduction of a common currency, the euro, and the establishment of the Schengen Area to allow easier travel and work across borders, are prime examples of the EU's commitment to economic integration. Despite retaining their sovereignty, EU member countries have agreed on policies in economic, defense/security, foreign, immigration, and labor issues to support a high standard of living and compete in the global economy.
