A simple example of the creation and development of a Communal Understanding (a community) can be found in the book "The Great Trek" by Oliver Ransford. This history of the Boers describes how these people came together and formed a communal understanding, expressed in its own unique language: Afrikaner. It also reveals the essential role of violence necessary for the Boers to assert themselves among other communities. Indeed, Boer tradition celebrates victories like Vegkop and Blood River as of crucial and lasting significance.
