An essential work in putting American history in perspective
Format: Hardcover
This is a great book. It is not a book for everyone, however. If you don't know the difference between the Pilgrims and the Puritans, and I don't mean just when they arrived, try something simpler. It is a fascinating read if you already have some knowledge. For example, had I not been familiar with Hudson River geography and history, I'm not sure I would have been able to follow Bailyn's account of New Netherland.
Naturally, as in any history, the most interesting stories are those you haven't heard before. For me, that was the information about New Sweden; I even read that section first. What makes Bailyn's book great, however, is his ability to make one see material one already knows a great deal about in new ways. Although he never addressed this question per se, he helped me answer a question that has been on my mind for at least fifteen years, and on which I've done considerable research - why did the Puritans, who arrived in 1630 as staunch Presbyterians, deriding their Separatist/Congregationalist Pilgrim neighbors, declare themselves Congregationalists in 1648 in the Cambridge Platform? (In part, the answer Bailyn helped me surmise is simply that when two or three Puritans gathered together, they had at least four different theological positions. It was hard enough to reconcile them in a single congregation; a presbytery would have been impossible.) The book also caused me to reassess my whole viewpoint on early Connecticut, and I certainly came to appreciate the importance of John Winthrop, Jr. beyond his role there. It is amazing too that Bailyn covers such a wide range of issues while devoting relatively few pages to each.
The review in The New York Times Book Review, at least as I recall it, was wrong. While that reviewer praised the Virginia, Maryland and New Sweden/New Netherland portions, the New England portion (about 40% of the book) was dismissed as being only of interest to genealogists. While it is true that the earlier sections were more reflective of the book's subtitle, "The Conflict of Civilizations," the New England section would be of interest to a rather small portion of the genealogical community. (For example, I learned nothing new about my only ancestor discussed in the book, William Vassall.) I doubt if that reviewer has ever seen an on-line genealogy, which frequently contain claims such as that so and so was born in 1585 in the United States. As I have already said, the New England section, like the rest of the book, does a marvelous job of putting information in perspective; something that anyone interested in history needs to do.

Interesting and important book
Format: Hardcover
This book looks at the motivations and demographics of the first wave of English immigrants to flee to what was to become the USA. Interestingly written, it explores the educations, positions of and the relationships of the earliest settlers to our east coast. I read it while researching our Family Tree and finding the people connected before coming, and for generations after. The endless Indian wars were a revelation, as was the tale of the oppressed becoming the oppressors as Quaker families fled Massachusetts for New Netherlands.

The Barbarous Years: The Peopling of British North America: The Conflict of... Bernard Bailyn
Format: Hardcover
A remarkable book!!!
I have never read such a comprehensive book on early United States history that contained so much information I had never read before.
How the status of "indentured servant" existed alongside the origins of slavery in Virginia and Maryland (along the Chesapeake Bay) was both remarkable and horrible.
That a white man (typically, landowner) could have a child with a (black) slave who would become a free person at adulthood (earliest laws) created problems (they needed the "help"), so this law of the 1650s-1660s was changed! And if a white (free) woman had a child with a (black) slave, the resulting child would remain a slave! Matrilineal or patrilineal human rights, that is the question.
Indentured servant, but with no expiration date.
I had never before read how people in this country were real "pioneers" in the creation of slavery - at least with slavery of humans captured from the continent of Africa! It seems that whatever voices of "Christian" decency there might have been at the time - church based values or ones simply based in the hearts of people living here - they were drowned out by commercial interests or those who simply couldn't be bothered by such concerns.
I hope you read this book and recommend it to your friends!
Sincerely,
Bob Cargill, Minneapolis
