In a historical context, colonies should be distinguished from protectorates and protected states, which though under British control, were nominally independent states, whereas colonies were part of the British state. They should also not be confused with Dominions, which, known collectively as "the Commonwealth", were independent states, held to be equal in sovereign status to the United Kingdom within the Empire and Commonwealth after the Statute of Westminster in 1931. Crown colonies, such as Hong Kong, were differentiated from other colonies in being administered directly by the Crown, without the degree of local autonomy found in self-governed colonies and other British overseas territories such as Bermuda.
