Renunciation of citizenshipRenunciation of citizenship is the voluntary loss of citizenship. It is the opposite of naturalization, whereby a person voluntarily obtains citizenship. It is distinct from denaturalization, where citizenship is revoked by the state. The common law doctrine of perpetual allegiance denied an individual the right to renounce obligations to his sovereign. The bonds of subjecthood were conceived in principle to be both singular and immutable. These practices held on in varying ways until the late 19th century.
National identityNational identity is a person's identity or sense of belonging to one or more states or one or more nations. It is the sense of "a nation as a cohesive whole, as represented by distinctive traditions, culture, and language". National identity may refer to the subjective feeling one shares with a group of people about a nation, regardless of one's legal citizenship status. National identity is viewed in psychological terms as "an awareness of difference", a "feeling and recognition of 'we' and 'they'".
