Writing history is not as easy as people sometimes think. Many assume it’s simply a matter of assembling a jumble of facts in chronological order, lacing the narrative with insights borrowed from academics and other authorities, throwing in one or two truly sensational details, and then rounding it all out with comparisons to contemporary events to make it relevant to readers. In fact, though, the real labor of history has little to do with writing down the brute facts of the past. It’s about understanding why people back then acted or spoke as they did, which means understanding the context in which events arose and unfolded. Explaining this context to readers is hard work and doesn’t come easily as praising or blaming historical figures for what they did or didn’t do.
