It is an understatement to say it is no easy task to summarize the events resulting in independence for not just one or two parts of Latin America, but the entire region. The result is a valuable attempt at a basic narrative of the events from approx. 1800 to 1825 that made the vast majority of the region free from direct control by its European colonizers and begin to think of government in vastly different terms. Aimed at readers who probably know little about these events, the book also works for anyone wishing to refresh her/his knowledge and provides many suggestions of additional reading if any part of the narrative excites you.
Chasteen chose to write primarily in chronological order, meaning he gives brief snippets of events in one location, then in another, and another, and so on. This certainly helps to put events across the region into context with each other, I am not sold on this as the best method to tell the history. One reason for this is Chasteen does not always make clear how events in one location affects those in another -- if they did at all (except for how events in Europe affected those in Latin America). The movements in each region are sometimes vastly different and except for timing, it is not easy to always conclude how they are related (if at all). The method also makes it difficult to follow the named persons of each narrative, and gosh are there a lot of them. He provides a helpful listing of the names (and some pictures) at the beginning of the book, but the minute details he sometimes goes into, and including persons that only appear for a page or two in the entire book (or once every 15 pages), makes it extremely difficult to follow.
When Chasteen moves away from the narrative, he is at his best. His explanation of the movements in terms of the PR campaign of "Americanos," how that worked during the movements and then lost its power afterwards, and explanation of the connections of it to the ideas of republicanism and popular sovereignty explain a lot when it comes to how and why the independence movements happened, failed, and then worked. Balancing the "Americanos" with the arguments and actions of those who did not want independence (especially once the Spanish begin sending armies) would have provided a more complete picture.
One item I found perplexing: I agree independence was a surprise and those who led it were a minority group in their regions. But, once things began, "republicanists" and "patriots" (and educated ones) seem to appear everywhere -- as do the, at the time radical, ideas of revolution -- -and they organize quickly and well. Just how this happened, and the seemingly preexistence of these organizations/ideas/people, is not fully explained.
