Investigating the Hidden Chamber (Full Episode) | Kingdom of the Mummies | National Geographic

The excavation at Saqqara reveals the first known underground mummification complex, where embalmers performed evisceration and used an ibu tent for preservation. The discovery of six canopic jars in Didi Bastet's burial suggests that the embalmers may have up-sold additional organ preservation, possibly including the brain and kidneys, which were traditionally not embalmed.

Exploring the History & Hysteria of Witch Trials | Truth Behind the Trials MEGA Episode | Nat Geo

The video argues that witch trials were driven by a combination of religious zeal, social tensions, and legal breakdowns, often targeting vulnerable women. It illustrates this through the case of Elizabeth Clark, whose confession under torture led to a massive witch hunt in 1645 England, and highlights how figures like Matthew Hopkins exploited the chaos of the Civil War to gain power and influence. The narrative also shows that such hunts could spiral out of control, as seen in the Trier trials where even a wealthy judge was executed, and in Sweden's Great Noise, where child testimony led to mass executions.

Are We Alone? The Search for Alien Life (Full Episode) | UFOs: Investigating the Unknown | Nat Geo

The search for alien life is shifting from government secrecy to independent scientific efforts, as researchers argue that new data collection by citizen scientists is the key to understanding UAPs. For example, physicist Mitch Randall is developing a passive radar network that could be deployed nationwide to track anomalous objects, while Avi Loeb's expedition to recover interstellar meteor fragments from the Pacific Ocean illustrates how independent projects can yield tangible evidence. However, the episode also highlights the ongoing controversy over such claims and the need for rigorous scientific scrutiny.

Draining the Ocean to Reveal History's Lost Pirate Ships | Drain the Oceans MEGA Episode | Nat Geo

The episode argues that modern underwater scanning and excavation technologies allow archaeologists to uncover and reinterpret historic shipwrecks, revealing not just treasure but also illicit trade and naval history. For example, the excavation of the Rooswijk uncovered smuggled silver coins, showing that the Dutch East India Company's crew widely participated in private trade. The program also demonstrates how legal disputes over recovered treasure, such as the case of the Nuestra Señora de las Mercedes, hinge on proving the wreck's identity and national ownership.

Birth Of The Empire (Full Episode) | Genghis Khan: Secret History of the Mongols | Nat Geo

Chinggis Khan's rise to power in 1206 was marked by a reorganization of the Mongol military and administrative structures, creating a centralized empire under his sole authority. He used a combination of diplomatic marriages, military tactics like the feigned retreat, and psychological warfare to subdue neighbors such as the Tangut and the Jin Empire. The episode argues that his success was due to both his military innovations and his ability to adapt and incorporate diverse peoples and technologies into his expanding realm.
