why was it built?

Answer 1

Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall that connects the remaining fortifications along the empire's new northern frontier.

Answer 2

I hope that I am interpreting this correctly as it is in the China section.

If you are referring to the Great Wall of China it was built to protect China's border.

Protecting the people within the wall from the invading Mongolians, and protecting the tea and silk routes for the continuing economy of the country.
