Corduene is a really old place that used to exist a long, long time ago. It was located in the mountains and valleys of what is now modern-day Iraq and Turkey. People who lived there were called the Corduenians.
They were very good at making weapons and fighting in wars. They were very tough and strong, but they also knew how to be sneaky and clever. They had a king who ruled over them and he was very important to them.
But eventually, the Corduenians were conquered by other people who were even stronger and had better weapons. And so, over time, Corduene faded away and became just a memory. But we can still learn about their bravery and their way of life from stories and history books.
