Great Inca Rebellion: Great Inca Rebellion presents stunning new evidence that is changing what we know about the final days of the Inca Empire. According to traditional accounts, the mighty Inca were swiftly wiped out by a small band of Spanish conquistadors. But new evidence had been unearthed that supports a different version of the story. Uncovered remains of those who died in battle along with recently discovered documents suggest that even after forming military alliances with thousands of Indian mercenaries, it took the Spanish many years to defeat the Inca Empire. Brought to life through CGI reconstruction and re-enactments, the untold epic saga of guerilla warfare and rebellion are revealed as National Geographic reveals the truth behind the Incas last stand. Royal Maya Massacre: Sixteen skeletons, the remains of a 9th century Maya royal family, are discovered in a mass grave, revealing a sordid tale of sex, greed, rivalry and the final clues to one of the greatest mysteries of the ancient world: what caused the collapse of the Maya Empire? The royal massacre and subsequent collapses of other kingdoms suggest a bloody power struggle among rival royal families. The royal practice of taking multiple wives - once thought to create alliances among warring Maya kingdoms - actually had the opposite effect. After generations, the growing royal families produced too many princes, and in turn, too many rivalries for all to survive. Exclusive access to one of the most important finds in Maya archaeology combined with the latest in forensics, gripping recreations and advanced computer graphics presents a dramatic tale of how sex, greed and royal power struggles led to the undoing of an ancient superpower. Secret Cities of the Amazon: Over the centuries, explorers traded tales of a lost civilisation amid the dense Amazonian rainforest. Scientists dismissed the legends as exaggerations, believing that the rainforest could not sustain such a huge population until now. A new generation of explorers armed with 21st-century technology has uncovered remarkable evidence that could reinvent our understanding of the Amazon and the indigenous peoples who lived there. Using CGI and dramatic re-creations, we re-imagine the banks of the Amazon 500 years ago, teeming with inhabitants living in the Secret Cities of the Amazon.
