Imagined communities
The Imagined Community is the concept strongly supported by Benedict Anderson which states that a nation is socially constructed and ultimately imagined by the people who perceive themselves as part of that group. The main causes of the nationalism that derives from the imagined community are the reduction of privileged access to particular script languages (such as Latin), the movement to abolish the ideas of divine rule and monarchy, as well as the emergence of printing press capitalism - all phenomenon occurring with the start of the Industrial Revolution.
