Identify and explain a cause and effect relationship between what is depicted in the map of Constantinople entitled “Trade about AD 1000” and Benjamin of Tudela’s description of Constantinople.

The relation that can be established between the map and Benjamin's description is very simple: the map illustrates how Constantinople was in the middle of several trade networks, that connected Europe, the Middle East, and Northern Africa.

Explanation:

This is because of the strategic location of Constatinople, in front of the sea of the strait of bosphorus, which forms a very good port, and that connects Europe with Asia (the Anatolian peninsula).

Because trade brings wealth to a ctiy, Benjamin describes the Constantinople as being very rich, perhaps almost as rich as Baghdad, which was the capital of the Islamic world at the time. Bejamin writes that people in Constantinople speak Greek, wear expensive silk garments, and many kinds of jewelry, which shows off their wealth.
