European communities are groups of countries in Europe that work together to help their citizens. Each European community has its own rules and regulations that all of the countries need to follow. For example, some European communities might allow people to travel and work freely between different countries without needing a visa, while others might require visas and other restrictions. All European communities also work to share resources and help each other out, so that everyone has more opportunities to do things like travel, get a job, or get an education.
