Karl May was a man who lived a long time ago and wrote many stories that people really enjoyed. He wrote about exciting adventures and brave heroes who went on dangerous quests and fought bad guys. He made up lots of characters, like a man named Old Shatterhand who was really brave and a cowboy named Winnetou who was really smart.
Karl May wrote these stories in a language called German, which is spoken in a country far away from where you live. Even though he wrote his stories a really long time ago, people still like to read them today because they are so fun and exciting!
