Templar Matthew and Sultan Baibars - Blood Brothers Across the Divide

The mid-thirteenth century Crusader states operated under sustained Mamluk ("Egyptian") military pressure, with successive Templar fortresses falling between 1265 and 1271. Against this background of territorial contraction, a Latin notarial source records a sworn blood-brotherhood between a Templar preceptor and the Mamluk sultan.
