A Society on the Edge

CHAPTER 3 · OUTREMER · The Crusades, 1095–1291

Look how thin the red is. The crusader states are a coastal ribbon, rarely more than a hundred kilometres deep, that somehow governs for the better part of two centuries. How? Not by numbers — there were never enough Franks — but by stone and by sea. A network of great castles like Krak des Chevaliers let a few thousand knights dominate the countryside from strongpoints; the whole society is organized around holding, not expanding.

The turn: Ascalon, 1153 — the high-water mark.

This chapter is one scene of an interactive atlas: the map repaints as the dates advance, campaigns draw themselves, and every chapter argues its causes and consequences — then a field exam asks you to prove it on the map.
