John Ellis explains how the attitudes that different peoples and nations had toward each other for most of recorded history have undergone a profound change during the last 500 years. At the start of this period, in 1500 AD, neighboring countries or tribes regarded each other mostly with apprehension when not outright fear and loathing—and for good reason given the conditions of those times. Tribal or racial attitudes were then virtually universal, no one people being much better or worse than any other in this respect. But during the next five hundred years a completely different attitude slowly gained ground. This was the idea expressed succinctly in the Latin phrase: gens una sumus—we are all one people. It has by now become a modern orthodoxy, however inconsistently or even hypocritically it may sometimes be embraced. This book tells the story of how the transition happened, setting out the crucial stages in its progress as well as the key events that moved it forward, and identifying the individuals and groups that brought about its eventual success.  This is a compelling story in its own right, but it’s one for which there’s an urgent practical need at the present time because an accurate grasp of how this crucial change happened contradicts everything that today’s race hustlers want us to believe. Ideologies such as Critical Race Theory, and Diversity, Equity and Inclusion have everything that matters backwards. The villains in their ignorant version of history are in reality the heroes of this story. Because Ellis’s book explains how the historical record makes nonsense of CRT, it amounts to the most fundamental and complete refutation of that destructive ideology.
