When the armies of the Rashidun Caliphate entered Jerusalem in 638, the city was quite different from what it is today–one of the most important cities for three religions.

As John Hosler writes in his latest book, Jerusalem Falls: Seven Centuries of War and Peace (Yale University Press, 2022):

“Three things may seem nearly inconceivable to modern readers: that the Temple Mount, a place of such incredible significance and symbolism, once served as Jerusalem’s garbage dump; that it once went wholly unmentioned in a political treaty; and that a conqueror essentially acquired it with little effort.”

Throughout his book, starting from the Persian invasion of 614 and ending with the Sixth Crusade in 1229, John explains how these successive “falls” of the city to invaders ended up setting the boundaries for inter-religious relations for centuries afterward. Invaders may have wanted to expel their religious competitors–but soon learned that governing the city without their help was impossible, eventually settling on a system of grudging tolerance and respect for each other’s holy sites.

In this interview, John and I talk about the many “falls” of Jerusalem: to the Persians, the Arabs, and the Crusaders, and how the many negotiations over the city helped build a durable status quo that persisted for centuries.
