Answer 2

Answer:

Unlike the modern era, there was no internet or any other source to keep the record of everything in the past. Kings used to have inscriptions on temple walls and copper plates to make people learn about their ruling nature and period of the study.

It was a great source for the visitors to learn about the values and laws of the rulers. Today, many historians rely on coins, carved walls, and plates to get information about the kings.
