Study of ancient history
Finding facts about ancient history is difficult because people wrote less in those times and much of what they did write has been lost. There were very few copies made because there was no printing. What people wrote they wrote by hand. More people could read and write in Ancient Rome than in other places but much of what they wrote is now lost. Historians also look at things that were made and used in ancient history to learn more about it.
Archaeology is looking at things that were made or used in the past to learn about that time. Things like clay pots, solid tools, and metal weapons can stay the same during a long time. Things like paper, wood, and cloth can be easily broken, burnt or damaged.
