The Unalterable Truth
Format: Paperback
The publisher's description of this book claims that there would be a severe reaction within American society due to the facts Professor Stannard brought to light. There was, unfortunately yet not unexpectedly, not much of a response to the horrifying truths revealed in his compelling narrative on the fate of the Western Hemisphere's indigenous people. Most Americans simply do not seem to care whether their nation's history, from the moment Columbus set foot in "The New World" and claimed that the people he encountered would make good slaves to the immediate present, is bathed in copious amounts of indigenous people's blood. The European's behavior when they were unleashed upon the unsuspecting Native Americans reveals not only their homicidal nature and destructive approach to a relatively pristine world; but their unfathomably horrid and continuous attempts to keep the destruction and death going. Extermination was the name of the game and even a cursory glance at the American newspapers of the nineteenth century reveals a national psychology which leaves one in a vast and endless state of confusion and disbelief. But it's all true. The phrase, "The Final Solution" was coined by nineteenth century Americans, not Hitler's Germany. Tens of millions perished, an eternal food source, the buffalo herds, were almost rendered extinct and while all this was occurring the people of Africa were chained to their masters' bidding. The people of Iraq understand. So do the Vietnamese and now the Syrians and many, many, many more. Of course, on publication Dr. Stannard was labeled a crank for mostly revealing that American "exceptionalism" is merely a high falootin' excuse for mass death and destruction.

Horrifying but it is a must read
Format: Paperback
This book should be required reading for all high-school students rather than the friendly history books that treat Columbus as a hero. This man was a murderous psychopath. Strong words but after reading this powerful text you will agree. I am ashamed at what these monsters from Spain, and England and elsewhere did soon after Columbus "discovered" the Americas. And all of the sacred knowledge lost. Everything the Mayans wrote down was burned. Knowledge from prehistory--all gone. All of the knowledge from prehistory the Indians in the Amazon basin held, all of the technology on agriculture, building, medicine, sacred knowledge, and much more gone. And for what?
I cannot tell you how powerful this book is. I cannot get it out of my head. If you think black lives matter well, sorry folks indigenous Indians of the New World MATTER MORE. They should be rioting for compensation from Spain and England. Oh, I forgot, nobody's left to riot.
It was a complete deliberate genocide killing perhaps 80 million paleo-indians from the 15th century on. And they are still killing the rest of them in Mesoamerica and esp. the Amazon where oil and mineral companies are murdering the remainder. And nobody seems to care! Read this book and learn the truth finally.

In 600yrs. , life itself, is elusive
Format: Paperback
American Holocaust or books related to the Native American should be required reading. The carnage or genocide, on the inflicted erased thousands of years of culture. We have lost so much which makes us, all less. Hispaniola, had a population of 8,000,00, in 1496. By 1535 they were extinct. Equivalent to N.Y. city today. Spanish and British. One looking for gold, the latter imposing European values, to steal land. But what was most fascinating, the religious hypocrisy. To kill, enslave, torture in the name of God. Who snatches babies from their mother, and feeds them to dogs, hanging natives from a gibber, and burned alive, brand enslaved women's faces every time they are resold ? The British and Spanish were the "Very ministers of Hell".

Academic / Thought-Provoking
Format: Paperback
They Were Her Property: White Women as Slave Owners in the American South is a powerful, eye-opening work that challenges long-held assumptions about slavery and gender in American history. Stephanie E. Jones-Rogers thoroughly dismantles the myth that white women were passive or marginal participants in the institution of slavery. Through meticulous research and extensive use of primary sources, including legal records, letters, and testimonies from formerly enslaved people—the book reveals that many white women were active, knowledgeable, and often brutal slave owners in their own right.
What makes this book especially compelling is how it centers the voices and experiences of enslaved people to expose the economic, legal, and physical power white women wielded. Jones-Rogers shows that white women not only benefited from slavery but also enforced it, defended it, and used it to build wealth and social status. The writing is clear, authoritative, and accessible, making complex historical arguments understandable without oversimplifying them.
This book is an essential read for anyone studying American history, slavery, race, or gender. It forces readers to confront uncomfortable truths and rethink narratives that have long softened or excused the role of white women in slavery. They Were Her Property is both academically rigorous and deeply impactful—a necessary contribution to honest historical understanding.

Remarkable analysis of slaveholding women in Antebellum America
Format: Paperback
Stephanie Jones-Rogers has provided us with a book that looks at the South's "peculiar institution" through a very different lens - the slaveholders/slaveowners, but this analysis looks at women that owned slaves, thus opening up a new avenue of study that I hadn't previously seen.
Jones-Rogers offers a well written account that is rich in historical details. She demonstrates through vivid historical evidence that the women that owned enslaved people were primarily driven by economic motives, and that these women were just as demanding and could be just as harsh as the "typical" slaveowner image that has been crafted over the years.
The book is organized thematically, and each chapter demonstrates the economic motivation behind slave ownership. The reader is offered views of everything from young children becoming slave owners when their parents "gifted" them an enslaved person, and how these young girls were taught that this was "property" that could be used as desired to how these female slaveholders would sell their slaves to meet their economic goals.
All told, this is a fascinating book that uncovers a long ignored slice of Antebellum American history that makes the historiographical literature of pre-Civil War history much richer.
