1898 is quite a memorable year for one big reason; it marks the start and end of the Spanish-American war, the first adventure of the USA’s imperial phase, and the making of one of its most zeitgeist-setting leaders, Theodore Roosevelt. On the plus side this means the year is easier to research, but on the downside, the focus is usually blinkered.
When I’m scouting around for research sources through my strange little narrow frame, the most obvious thing to look at is “books about years.” This is the first one I’ve encountered so far (there are many, many more to come once we get into the 20th century) and is not the best, or the worst introduction to the genre. While supposedly about the events of 1898, the book is mostly (say 80%) about the Spanish-American war, from an entirely American perspective, and even the context setting introduction and conclusion are only basically lists of events in the USA. I guess this is fair enough, the war was nicely contained by the year, though the repercussions in Cuba and The Philippines would continue for decades after, and expecting American historians to take an international perspective is obviously wishful thinking. The war is described well-enough, taking a pretty even-handed approach to the rights and wrongs of it, but the analysis is a bit limited, events are covered in a reasonable depth, with no extra time taken on analysing deeper issues. Not sure I would recommend it, but I’m not giving it to Oxfam.
In the same sort of quality, but preferable due to being consumable in two hours, here’s a fairly dry PBS documentary with a host of military historians in front of bookshelves and hoary voice actors playing McKinley, Roosevelt and the rest.
