Master race
Arthur de Gobineau (1816–1882) believed that cultures become bad when races mix. In his book Moral and Intellectual Diversity of Races (, 1853–55), de Gobineau states that the mix of races has a bad influence on culture. In his view, the development of culture is linked to that of race. When empires are created, this leads to a mixing of races. According to de Gobineau, this would lead to degeneration and the downfall of the respective empire.
