There are also three Crown dependencies, Guernsey, Jersey and the Isle of Man, in the archipelago which are not part of the United Kingdom, although the United Kingdom maintains responsibility for certain affairs such as international affairs and ensuring good governance, on behalf of the British crown, and can legislate directly for them. These participate in the shared institutions created between Ireland and the United Kingdom under the Good Friday Agreement. The United Kingdom and the Crown dependencies form what are called the "British Islands".
