Discovered near modern-day Baghdad in the 1930s, a small clay vessel containing a copper cylinder and an iron rod sparked one of the most enduring debates in alternative archaeology. Could this object, now known as the Baghdad Battery, represent evidence of ancient electrical knowledge?

In this episode of History Undisclosed, we take a careful, evidence-based look at the artifact’s discovery, construction, and historical context. We examine the experiments that claim it could generate electricity, the serious objections raised by archaeologists and engineers, and the alternative explanations that often receive far less attention.
