How did globalization come about?

There is fierce debate among scholars about when globalization began. The debate stems partly from the lack of a precise definition of the word. Some argue that globalization as a phenomenon began with the earliest human migratory routes, or with Genghis Khan's invasions, while others view it as far more contemporary. Many view globalization in its current form as a modern phenomenon, beginning no earlier than World War II. The term itself has been in common use since the 1980s
