Every empire is ruled by the master race, Glubb notes:
The people of the great nations of the past seem normally to have imagined that their pre-eminence would last for ever. Rome appeared to its citizens to be destined to be for all time the mistress of the world. The Abbasid Khalifs of Baghdad declared that God had appointed them to rule mankind until the day of judgement. Seventy years ago, many people in Britain believed that the empire would endure for ever. Although Hitler failed to achieve his objective, he declared that Germany would rule the world for a thousand years. That sentiments like these could be publicly expressed without evoking derision shows that, in all ages, the regular rise and fall of great nations has passed unperceived. The simplest statistics prove the steady rotation of one nation after another at regular intervals.
The belief that their nation would rule the world forever, naturally encouraged the citizens of the leading nation of any period to attribute their pre-eminence to hereditary virtues. They carried in their blood, they believed, qualities which constituted them a race of supermen, an illusion which inclined them to the employment of cheap foreign labour (or slaves) to perform menial tasks and to engage foreign mercenaries to ?ght their battles or to sail their ships.
These poorer peoples were only too happy to migrate to the wealthy cities of the empire, and thereby, as we have seen, to adulterate the close-knit, homogeneous character of the conquering race. The latter unconsciously assumed that they would always be the leaders of mankind, relaxed their energies, and spent an increasing part of their time in leisure, amusement or sport.
In recent years, the idea has spread widely in the West that ‘progress’ will be automatic without effort, that everyone will continue to grow richer and richer and that every year will show a ‘rise in the standard of living’. We have not drawn from history the obvious conclusion that material success is the result of courage, endurance and hard work — a conclusion nevertheless obvious from the history of the meteoric rise of our own ancestors. This self-assurance of its own superiority seems to go hand-in-hand with the luxury resulting from wealth, in undermining the character of the dominant race.
