A nation is not any casual collection of people. At the same time it is also different from other groups or communities found in human society. It is different from the family which is based on face-to-face relationships with each member having direct personal knowledge of the identity and character of others. It is also different from tribes and clans and other kinship groups in which ties of marriage and descent link members to each other so that even if we do not personally know all the members we can, if need be, trace the links that bind them to us. But as a member of a nation we may never come face to face with most of our fellow nationals nor need we share ties of descent with them. Yet nations exist, are lived in and valued by their members.

It is commonly believed that nations are constituted by a group who share certain features such as descent, or language, or religion or ethnicity. But there is in fact no common set of characteristics which is present in all nations. Many nations do not have a common language, Canada is an example here. Canada includes English speaking as well as French speaking peoples. India also has a large number of languages which are spoken in different regions and by different communities.

A nation is to a great extent an ‘imagined’ community, held together by collective beliefs, aspirations and imaginations of its members. It is based on certain assumptions which people make about the collective whole with which they identify.

Second, people who see themselves as a nation also embody a sense of continuing historical identity. That is, nations perceive themselves as stretching back into the past as well as reaching into the future... Thus nationalists in India invoked its ancient civilisation and cultural heritage and other achievements to claim that India has had a long and continuing history as a civilisation and that this civilisational continuity and unity is the basis of the Indian nation.

Third, nations identify with a particular territory. Sharing a common past and living together on a particular territory over a long period of time gives people a sense of their collective identity. It helps them to imagine themselves as one people.

Fourth, while territory and shared historical identity play an important role in creating a sense of oneness, it is a shared vision of the future and the collective aspiration to have an independent political existence that distinguishes groups from nations.

Many people believe that a shared political vision about the state and society we wish to create is not enough to bind individuals together as a nation. They seek instead a shared cultural identity, such as a common language, or common descent. There is no doubt that speaking the same language makes it easier for us to communicate with each other and sharing the same religion gives us a set of common beliefs and social practices.
