For the other countries, the date given may not represent "independence" in the strict sense, but rather some significant nationhood event such as the traditional founding date or the date of unification, federation, confederation, establishment, fundamental change in the form of government, or state succession. Dependent areas include the notation "none" followed by the nature of their dependency status. Also see the Terminology note.
