When you’re writing a historical narrative, you can’t explain everything — you have to assume that your audience has a certain level of knowledge. But it’s tricky to establish just what that baseline should be. You don’t want to insult your readers’ intelligence by overexplaining, but you also don’t want to leave them confused.

And as a reader of historical narratives, you want to look for books that set that baseline appropriately for you. (Of course, the same general principle applies when you’re reading anything, from a cookbook to a treatise on mathematics, but I’m focusing on history here.) I find it helpful to have this issue in mind whenever I begin reading a work of history, because if I’m alert, I can know within a few pages whether a given book will work for me.

One of the most famous classics of historical writing is Jacob Burckhardt’s The Civilization of the Renaissance in Italy, first published in 1860. Here is a characteristic passage from the early pages of that book:

The internal condition of the despotically governed States had a memorable counterpart in the Norman Empire of Lower Italy and Sicily, after its transformation by the Emperor Frederick II. Bred amid treason and peril in the neighbourhood of the Saracens, Frederick, the first ruler of the modern type who sat upon a throne, had early accustomed himself to a thoroughly objective treatment of affairs. His acquaintance with the internal condition and administration of the Saracenic States was close and intimate; and the mortal struggle in which he was engaged with the Papacy compelled him, no less than his adversaries, to bring into the field all the resources at his command. Frederick’s measures (especially after the year 1231) are aimed at the complete destruction of the feudal State, at the transformation of the people into a multitude destitute of will and of the means of resistance, but profitable in the utmost degree to the exchequer. He centralized, in a manner hitherto unknown in the West, the whole judicial and political administration. No office was henceforth to be filled by popular election, under penalty of the devastation of the offending district and of the enslavement of its inhabitants. The taxes, based on a comprehensive assessment, and distributed in accordance with Mohammedan usages, were collected by those cruel and vexatious methods without which, it is true, it is impossible to obtain any money from Orientals. Here, in short, we find, not a people, but simply a disciplined multitude of subjects; who were forbidden, for example, to marry out of the country without special permission, and under no circumstances were allowed to study abroad. The University of Naples was the first we know of to restrict the freedom of study, while the East, in these respects at all events, left its youth unfettered. It was after the examples of Mohammedan rules that Frederick traded on his own account in all parts of the Mediterranean, reserving to himself the monopoly of many commodities, and restricting in various ways the commerce of his subjects. The Fatimite Caliphs, with all their esoteric unbelief, were, at least in their earlier history, tolerant of all the differences in the religious faith of their people; Frederick, on the other hand, crowned his system of government by a religious inquisition, which will seem the more reprehensible when we remember that in the persons of the heretics he was persecuting the representatives of a free municipal life.

That’s only part of a paragraph, by the way. Historians wrote long paragraphs in those days.

Here are some of the things that Burckhardt expects that you already know:

  • What the Norman Empire of Lower Italy and Sicily was
  • Who Emperor Frederick II was
  • What the Saracenic States were
  • What struggle Frederick had with the Papacy
  • What “measures” Frederick took, especially “after the year 1231”
  • What “Mohammedan usages” are
  • What the “cruel and vexatious methods” of Frederick’s tax-collecting were
  • In what way the University of Naples “restrict[ed] the freedom of study”
  • What Burckhardt means by “the East”
  • What “Mohammedan rules” Frederick followed
  • Who the Fatimite Caliphs were
  • What their “esoteric unbelief” was
  • What the nature of Frederick’s “religious inquisition” was
  • What heresies he attempted to put down
  • Who “the representatives of a free municipal life” were

Now, I have firm knowledge about a couple of these things and an in-the-ballpark awareness of a few more, but beyond that … the less said, the better. So maybe this book is not for me.

But The Civilization of the Renaissance in Italy is a very important and influential book! Yes, it is. But that doesn’t mean that it’s something I need to read – not until I acquire the requisite knowledge, which, let’s face it, I am not especially likely to do.
