Answer:
He defined a nation as "an imagined political community".As Anderson puts it, a nation "is imagined because the members of even the smallest nation will never know most of their fellow-members, meet them, or even hear of them, yet in the minds of each lives the image of their communion".[1] Members of the community probably will never know each of the other members face to face; however, they may have similar interests or identify as part of the same nation. Members hold in their minds a mental image of their affinity: for example, the nationhood felt with other members of your nation when your "imagined community" participates in a larger event such as the Olympic Games. Finally, a nation is a community because, regardless of the actual inequality and exploitation that may prevail in each, the nation is always conceived as a deep, horizontal comradeship. Ultimately it is this fraternity that makes it possible, over the past two centuries, for so many millions of people, not so much to kill, as willingly to die for such limited imaginings.
