The history of the British Isles has witnessed intermittent periods of competition and cooperation between the people that occupy the various parts of Great Britain, Ireland, and the smaller adjacent islands, which together make up the British Isles, as well as with France, Germany, the Low Countries, Denmark, Scandinavia, etc.
Today, the British Isles contain two sovereign states: the Republic of Ireland and the United Kingdom. There are also three Crown dependencies: Guernsey, Jersey and the Isle of Man. The United Kingdom may be further broken down into the four countries of the United Kingdom: England, Northern Ireland, Scotland, and Wales. Each of these countries bears its own history, with all but Northern Ireland having been independent states at one point. The History of the formation of the United Kingdom is very complex.
