The opening chapter of Zinn's book is an essay on the political content of history. With Christopher Columbus as the case in point, Zinn shows that by choosing to emphasise certain facts, and downplay others, mainstream historians - in fact, all historians - stake out a political position. Even, or perhaps especially, when they would say they are being 'neutral' or 'objective'. In history and, by implication, the present; perspective matters.
That is why Zinn tells the story of the United States, not through the eyes of its statesman, great financiers, generals or industrialists, but through the eyes of ordinary people. That is to say: the displaced Native Americans, the enslaved Black people, the women struggling for the vote, the exploited working class, the civil rights movements, and the victims of US foreign policy during the Cold War.
This is remarkable. The popular narrative of the United States as land of liberty and opportunity is stripped bare, and torn down. In its place: a nation of contradictions and tensions, built on class war, ethnic cleansing, and manifold other repressions.
Now, in fact, a similar story could be told about a great many countries in the world. One reason it is particularly worth listening to Zinn's story about the US, is that the myth of the US, and its emancipatory principles, is so strong. As the premier world power of the present day, it does us well to understand where that power comes from.
Most important of all, this is neither a bleak book, nor a preachy one. It is a great work of narrative history, and as such lays as much emphasis on the courage and achievements of ordinary people, as it does upon their suffering. A great piece of writing. A book for our times, courageous and humane.
