The British Crown Dependencies are three self-governing territories: Jersey, Guernsey, and Isle of Man. They are not part of the United Kingdom but are under its sovereignty. Each dependency has its own government and legal system, allowing them to manage local affairs independently. These territories have a unique relationship with the UK, which is responsible for their defense and international representation. The Crown Dependencies are known for their financial services, tourism, and agriculture, contributing to their economies while maintaining a distinct cultural identity.
