    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

    A decent primer -- no more.
    Format: Hardcover
    This is an odd book for one of America's premier historians. It isn't a bad book -- a person of Bailyn's erudition couldn't write a bad book -- but it doesn't hang together well. The author does not really have anything new to say and a historian of the Early Colonial Period will quickly recognize the usual sources. It is hard to see exactly what historiographical niche this book fills. Even the title is misleading. Sure, Jamestown was barbarous enough by our standards and New Amsterdam was plenty harsh. But, the Bay Colony was, by the rough-and-ready standards of 17th century Europe, pretty civilized. (Compare it with the contemporaneous English Civil War or the Thirty Years War.) As for "Conflict of Civilizations," there was certainly enough of that but the most interesting part of the book, the last third or so on the Bay Colony, is largely an account of Puritan theological quarrels. In fact, one senses that Bailyn felt like he was "home" when he wrote about the Bay Colony. He has, after all, written about New England since 1955 ("Merchants.") He gives the reader a clear account of the theological duels between Winthrop, Cotton, Hooker, Williams, Hutchinson and others. But, others have done this as well or better. Bailyn all but ties himself in a knot to be politically correct toward the Native Americans. For every Indian atrocity he finds a matching atrocity in European civilization. Still, if captured in war one was likely to be a lot better off among the English, French or Dutch than the Pequods. A LOT better off! This volume is part of a series that explores the settling of North America and hardly anyone is better equipped for this than the author. But, what begins as a good account of the horrors of Jamestown drifts into a twice-told tale of the niceties of Puritan disputation. It is almost as if Bailyn got bored half-way through and started channeling Perry Miller. A good book in its way and quite useful for an upper division course or first-year graduate seminar. But, not well-written enough to snare the casual reader and not original enough to snare the professional historian. An odd number.
