Modernity is linked to genocide through the idea that groups seen as hindering progress need to be eliminated. European settlers viewed Indigenous Australians as backwards and preventing modern European civilization, so sought to eliminate them. Similarly, Pol Pot and the Khmer Rouge believed Western influences in Cambodia prevented progress, so they eliminated those groups to create a fresh start for their society. While modernity preaches progress, genocide shows how the idea has also been used to justify the murder of innocent people when they are viewed as preventing the advancement of a group or nation.
