The Battle of Königsberg: The Brutal End of the Last Great German City | IN FULL COLOR

Discover unpublished and rarely seen photographs from the Battle of Berlin in 1945, brought together in an exclusive collection for history enthusiasts. More than 200 historical photographs take you through the final days of the Third Reich and reveal scenes rarely shown in documentaries. In the spring of 1945, as the Third Reich was collapsing on all fronts, one of Germany's most iconic cities was preparing to face its final days. Königsberg, the historic capital of East Prussia, had been a major cultural, military, and commercial hub for centuries. However, the unstoppable advance of the Red Army turned it into one of the last German bastions isolated from the rest of the country. Surrounded by Soviet forces and subjected to intense bombardment, the city became trapped in a siege that would mark the definitive end of the German presence in the region. The streets of Königsberg quickly transformed into a battlefield. Historic buildings were reduced to rubble as German soldiers, Volkssturm units, and desperate civilians attempted to resist an enemy vastly superior in numbers and firepower. House-to-house combat was extremely

The Brief, Violent Life of Billy The Kid

The orphan teen who became the most wanted man in the West. A fascinating look at the boy behind the myth, BILLY THE KID puts a human face on the legend who in just a few short years transformed himself from a skinny orphan boy to the most feared man in the West to an enduring icon. On April 28, 1881, twenty-one-year-old Henry McCarty, a.k.a. Billy the Kid, just days from being hanged for murder, outfoxed his jailers and electrified the nation with the latest in a long line of miraculous escapes. An outlaw with a deadly reputation, the young man was finally gunned down by the ambitious sheriff Pat Garrett just a few weeks later. The felling of one of the most notorious criminals of the age made front-page news and marked the end of Henry — but it was the beginning of one of the West’s most enduring legends. Demonized by the lawman that killed him, the Kid was soon mythologized by a never-ending stream of dime store novels and big-screen dramas, portrayed by everyone from Paul Newman

Lionel Richie was incredibly close to his grandmother, yet mystery surrounds the identity of her father because she would never talk about him.

The Lost Continent of Zealandia: What Was Erased 10,000 Years Ago

In 2017, scientists confirmed what geologists had long suspected: there is an eighth continent, nearly the size of Australia, sitting mostly submerged beneath the Pacific Ocean. They called it Zealandia. What they did not widely report is that significant portions of Zealandia were above water until approximately 10,000 years ago, exactly when ancient myths describe a global flood. Polynesian oral traditions speak of a great land to the west that sank beneath the waves. And geological surveys of the Zealandian shelf are revealing formations that bear an uncomfortable resemblance to man-made structures.

More than 200 historical photographs take you through the final days of the Third Reich and reveal scenes rarely shown in documentaries. World War II transformed the United States from a power trying to stay out of the European conflict into one of the most powerful military forces in history. While Germany was conquering much of Europe and Japan was expanding its dominance across Asia and the Pacific, Washington progressively supported the Allies with weapons, supplies, and economic aid. However, everything changed on December 7, 1941, when Japan attacked Pearl Harbor. The following day, the United States declared war on Japan, and a few days later, Germany and Italy declared war on the United States. The country officially entered a war that had already changed the world. Starting in 1942, the United States had to fight simultaneously on two massive theaters of war. In the Pacific, its forces faced the Japanese Empire in decisive battles such as Midway

Inside Mao’s China: The Great Leap Forward And The Cultural Revolution

The Chinese Chairman Mao Zedong once declared the death of 300 million of his own people would be a price worth paying. Supreme Leader of China for almost 3 decades, his merciless policies made him one of the most ruthless tyrants of the 20th Century. A communist leader obsessed by power and violence; a sadist intoxicated by others’ pain; and a dictator convinced that politics had to be violent. He presided over the deaths of more people than Hitler and Stalin combined. Those who dared oppose him paid the price in the most cruel way imaginable. China’s needless deaths were so great in number, the total may never be known. This is the story of a sadistic autocrat addicted to brutality, from his communist roots, through his reign of cruelty and revenge, to a position of authority so great, his personality cult remains to this day. -- Welcome to the official Get.factual the original video platform channel! 🌍 We are a documentary streaming channel covering history, science, technology, and nature.

Peter Thiel: The Architect of Dissidence | Money, Power and the Future of Silicon Valley

Peter Thiel: The Architect of Dissidence | Money, Power and the Future of Silicon Valley Peter Thiel has spent his career betting against consensus. From PayPal and Facebook to Palantir, political campaigns and billion-dollar investments, his influence reaches far beyond Silicon Valley. This Moconomy documentary explores how Thiel turned contrarian thinking into a strategy for wealth and power. It follows his path from chess prodigy and failed trader to PayPal co-founder, Facebook’s first major outside investor and the driving force behind Palantir — one of the world’s most controversial data and surveillance companies. But Thiel’s story is also about something larger: the growing overlap between technology, government, finance and political influence. From funding candidates and defense technology to preparing a private refuge in New Zealand, his investments reveal a worldview shaped by competition, control and a deep distrust of conventional systems. Is Peter Thiel building the future — or preparing for a world in which the systems we know no longer hold? Want to keep exploring the billionaires, technologies and networks reshaping global power?

Men in the modeling business

More and more men are dreaming of a career as a top model. But the competition is fierce. At places like the Hamburg Model Academy, which offers a sort of crash course for aspiring models, men learn the basics. Those who really make it can earn daily rates in the four-digit range — and see themselves on giant billboards. At the Model Academy, run by Hamburg modeling agency Modelwerk, young men learn how to pose, work the camera, and stride elegantly down the runway. It's a ruthless business: Many agencies quickly weed out models who don't make an immediate impression. The industry is looking for fresh faces, preferably with experience. "We send guys who are serious about it abroad for several months first," explains Claudia Midolo, founder and head of the Modelwerk agency. In places like Turkey, Vietnam, or Mexico, they gain practical experience, earn money, and yet remain fresh for the western market. A models' reach on social media is also becoming increasingly important. Having many followers is a clear advantage when it comes to landing good jobs. ______
