Should be required
Format: Paperback
In my opinion, this book should be required reading in high school/college history classes. It’s so important to learn accurate history when it comes to slavery and this book does that. White women played a larger role than we are taught. Please give this a read!

No regets
Format: Paperback
This was a good book to read! In school you only learn the male prospective during slavery! I know feel I can say white woman played a major role during slavery times. I like that fact that the Author put in the information to where we can go srwcah and read for ourselves. The visuals where an added touch. I feel like because alot of women of that time couldn't write so alot of information was missing. I feel like this is a must read.

One of the most poignant books I have read in a long time.
Format: Paperback
One of the most poignant books I have read in a long time.
“Southern communities, lawmakers, and courts recognized slave-owning women as individuals able to acquire and exercise mastery over enslaved people, s is evident from laws passed throughout the South. Laws dating back to the colonial period routinely recognized the mistresses owned enslaved people in their own right, and these same laws acknowledged the fact that these women were capable of exercising mastery over the enslaved people they owned.” Stephanie E. Jones - Rogers.
They were referred to as Southern Belles’. Revered for their ladylike daintiness. But… there was nothing dainty about their dealings for they too, owned human property. These white southern mistresses were heavily involved and often owned more property than their male counterparts even being the breadwinners. These women were barbaric and wore the crown of cruelty.
Dr. Rogers gave the enslaved a voice in this text – allowing our ancestors to share with us their story and experiences under the thumb of white mistresses. This text uncovers the extent of the involvement that white women had with slave ownership. There was discord in marriages due to white women struggles to maintain control of their financial gains of human property. These women utilized the judicial system to protect their pecuniary interests. The parents of these white girls/women bequeathed slaves to white females i.e. as young as newborns – which leads us to mistresses in the making – that is the education of young white women of the mastery of slave ownership. My heart broke as I was able to envision the accounts of atrocities inflicted upon our ancestors. Our people were raped and forced into being breeders and wet nurses to ensure the livelihood of these white mistresses and their families. The evidence is insurmountable in all the ways slave-owning women invested in, and profited from their financial ties to American slavery and its marketplace. Most importantly, there was testimony from formerly enslaved people of their experiences within slavery. This text is a mandatory read for all and in my opinion, must be included as part of the curriculum in schools.

Slave Trade was not only a White Man's Affair
Format: Kindle
The book is an excellent read particularly in today's climate. Why 53% of white women would put a vile man in office is explained in the pages of this book. White women held positions of power in the America slave trade, a fact overlooked in history. These southern bell's represented as the gold standard of woman hood in the antebellum south were anything but, and they for the most part showed as much, business savvy as down right cruelty in the slave trade. They benefited in every conceivable way from this free labor market. They were no advocates for the kind humane treatment of slaves. In many cases they were as vicious as their counterpart and just as committed to a keeping Blacks marred in the system of bondage. They are in most cases depicted as silent partners and where that might be the case many white women had full command and knowledge of the value of a slave they invested in and they wanted a hefty return. In fact they used every means on the table to keep these black, men, women and children bound to their wealth creation. These co-conspirators had more than a hand in the cookie jar, they enjoyed the power and did not hesitate to support the maintenance of this inhumane institution.

Excellent book, not only for lawyers or law students
To begin with, I am neither a lawyer, a law student, nor even a prospective law student. I am, however, someone who has always been interested in the law, primarily for two reasons. First, the law is the principal formal means a society uses to try to resolve conflict among the society's members. Second, and closely related to the first reason, the sum shape, both of content and procedure of the law, is an expression of exactly what a society's values are and the goals a society sets for itself or the standards by which it ideally wishes to be judged.
I found this book to be excellent, informative, well written, and even at parts entertaining. Although meant as a guide for law students to use to prepare for the strenuous exams that are associated with each course they will take in law school, the book provides much, much more, and hence my belief that it can profitably be read by a far larger readership than its ostensible audience. One of the key elements stressed throughout, and exemplified by numerous enlightening examples, is that there usually is no one correct answer to any given legal question. Arguments can be made on at least two sides of any matter based upon, for example, a "plain reading" of the text of a relevant law and the reasonably understandable intent of those who made the law (e.g., a legislature). The authors bring out clearly such sources of legal precedent as laws, government regulations, individual case law decisions by judges, common law, government policy, and specific codes (e.g., the Uniform Commercial Code, or UCC) and show how differing results to a case can readily come about based upon arguments using the different sources to bolster respective cases.
In reality, although by minimal definition a book designed, as said above, to prepare for the taking of law school tests, the book actually also is a good guideline on how to think (not necessarily what to think) about many larger issues in society, including politics and policy issues of all sorts.
Finally, the first two thirds of the book discuss ways to think about the wide range of questions that can be posed to aspiring lawyers and introduces the reader to understanding such distinctions as "forks in the law" and "forks in the facts" (a quite useful distinction to keep in mind). The final part of the book provides solid test taking strategies that are applicable to a wide range of academic testing (e.g., answer the question the professor actually asked and avoid wasting time or effort on ancillary matters not really germane to helping to resolve the issue.) Although some of these may seem obvious once read, the tips are the type of thing that, under pressure of exams, many students often forget to apply.
In sum, I highly recommend this book to those interested in life in the modern world.
