Middle Eastern trade routes offer an economic interpretation of the Crusades

An economic interpretation of the Crusades starts with the Middle East's position at the crossing of major trade routes. In this view, the income from controlling that traffic explains the attraction of the region beneath other stated motives. The Suez Canal supplies a later comparison: shipping gained a shorter alternative to the long voyage around the Cape of Good Hope, reducing the attraction of overland routes. Ottoman decline is linked to that change in the argument, without a detailed chronology to establish the connection here.
