The correct answer to this open question is the following.
How do ideas and beliefs shape our lives and the world around us?
I am going to use the reference of the trade routes, belief systems, Western European manorialism, and Feudalism.
It is well documented that humans today are the by-product of many influences of the past. We can see this in the family environment, in the way we conduct business, politics, and in society. We are creatures of habit and the past is our direct influence.
Trade routes such as the Silk Route not only exchanged goods but ideas, customs, values, and culture that spread through Asia, India, the North of Africa, and Europe.
This meant that many belief systems were passed from one nation to the other, and influenced the way people did things. These ideas were inherited with the pass of time and repeated from generation to generation.
Without a doubt, feudalism marked Western Europe in the Middle Ages. It was a way of living where wealthy people lived the good life exploiting poor people, peasants, that worked the landlord land for shelter and food. The Catholic church allied with the powerful kings of Europe and exerted too much control over their subjects and followers.
