A Minority View of our History
Format: Kindle
If you want to learn more about American history from the perspective of minorities, this is a crowning achievement. It is long so I focused on reading the chapters on the US and it gave me an understanding of just how brutal the challenges were but how significant the slow process of building our multicultural society was as well.

Eye opening!
Format: Hardcover
I've read tons of books and biographies connected to American history, perhaps because I'm the son of immigrants, but have never read a survey like this one. By describing in luscious and sometimes horrific detail the wars being fought in Mexico and the main Canadian provinces alongside our Civil War, we get patterns, intersections, and insights that simply would not be available reading about any one struggle. I love this book which is teeming with wonderful portraits and dramatic scenes.

A worthy and worthwhile fourth volume in the series
Format: Kindle
Once again, Taylor frames a critical period of the past in terms of the continent of North America and ties the US Civil War to the one occurring concurrently in Mexico and Canada's move toward Dominion. All thoughtfully told and expertly researched.

Good History Book
Format: Kindle
Twenty years that change history and the Americas. Even though the civil war ended slavery at a humongous cost, it it failed to bring social justice a d civil rights to the population of the country. It was not until 1920 that women were granted voting rights. And some problems and divisions persist nowdays.

interesting and fresh perspective on the American civil war
Format: Kindle
Fresh perspective on the well known American Civil War. I appreciate Dr Taylor’s emphasis on the preservation of slavery over the states’ rights argument for why the American Civil War was fought.
