This is a history book written for a general audience and it is about the United States and its territories. It explores why we have expanded, when we have expanded, how we’ve viewed territories, and the consequences of the views for both the people in the territories and the people at home.

I learned a lot reading this. I was aware that the U.S. still holds territories and that it has held more and different territories in the past, but hearing about how different territories have been treated and its connection to things like race and immigration rules was eye-opening. Thinking about things like citizenship has consequences for things like voting in national elections, so even if we don’t currently hold the all the territories we’ve historical held, this part of our history is still important because it does still impact us today. (If you’ll recall from the previous Presidential election where some of our citizenry were surprised to find that Puerto Ricans are U.S. citizens, but they can only vote in the presidential election if they live on the mainland.)

So, this was good and I would recommend it. I also recommend getting it as an audiobook. Luis Moreno’s narration is engaging and it carried me through places where dates and details may have stopped me if I had been reading if off a page.
