Dear little friend,
Etruria was a place a long, long time ago where people called Etruscans lived. Imagine it like a big playground where the Etruscans played and had their own special toys, like buildings and art and unique things they made. They had their own language too, but we don't use it anymore. Etruria was in the middle of Italy, which is a country in Europe, and it was important because people would trade and travel through there. Even though the Etruscans aren't here anymore, we can still find clues and learn about them by looking at the cool things they left behind, like buildings and art and things they made. And that's Etruria in a nutshell, my little friend.
