Given that there’s such little margin for error in a submersible, many submarine losses remain sources of intrigue and mystery, and during World War II, few sinkings were as controversial as the Surcouf, a Free French submarine that disappeared in the Caribbean in 1942. When the Surcouf launched in 1929, it was a technological marvel. This wasn’t a conventional submarine at all, but a 3,300-ton, 300-foot-long submersible light cruiser.

In popular media and culture, the Paleolithic era is often depicted as a time when humans were completely savage, spoke with little more than grunts, hit women over their heads with clubs and kidnapped them, and of course, everyone lived in caves. The reality is that the Paleolithic era was a time of great change when humans coalesced into groups and developed different technologies that helped them survive and ultimately thrive in harsh environments.

For millennia, people considered dragons to be real, and the vivid lore of dragons has touched societies from Central America to Europe, and from Egypt to China. The popularity of dragons can easily be assessed by the number of motion pictures that include them as an integral part of their narrative, from the friendly dragons of children’s cartoons to the monsters being bred underground to unleash their horrors on humanity.

Among the world’s most recognizable man-made structures, the Dome of the Rock–known in Arabic as the Qubbat as-Sakara–is also one of its most mysterious. Although much of the Dome’s construction, reconstruction, and later additions are well-known from historical texts and archeological work, what it represents, why it was built where it was, and even its use remain the subject of scholarly controversy.

The enduring image of World War I is of men stuck in muddy trenches, and of vast armies deadlocked in a fight neither could win. It was a war of barbed wire, poison gas, and horrific losses as officers led their troops on mass charges across No Man’s Land and into a hail of bullets. While these impressions are all too true, they hide the fact that trench warfare was dynamic and constantly evolving throughout the war as all armies struggled to find a way to break through the opposing lines.

Early in 1799, Napoleon advanced against France’s erstwhile enemy, the Ottoman Empire, invading modern Syria (then the province of Damascus) and conquering the cities of Gaza, Jaffa, Arish and Haifa. However, with the plague running rampant through his army and his lines of supply from Egypt stretched dangerously thin, Napoleon was unable to destroy the fortified city of Acre and was forced to retreat. The retreat cost him almost all of his wounded as, harassed by enemy forces, he was forced to abandon most of his casualties to the Ottomans’ mercy, or lack thereof.

It takes a special type of person to serve in a nation’s navy, especially on long voyages that separate men and women from their loved ones, and no service is both loved and hated as that aboard submarines, for very few people ever serve on them on a whim. For one thing, the psychological impact of being trapped for long periods underwater in tight, cramped quarters is more than many people can stand.

During the reign of the Artaxiad dynasty, Armenia became a hub of trade and commerce, connecting the Silk Road and the Mediterranean world. The Armenian kings encouraged the development of agriculture, commerce, and arts, and the kingdom became renowned for its skilled artisans, writers, and philosophers. Of course, given its central location, the dynasty also faced numerous challenges, including repeated invasions by the Roman and Parthian empires, internal conflicts, and economic hardships.

The crucial importance of education in China, a prized virtue instilled in the population among all classes by beloved teacher and philosopher Confucius in the 6th century BCE, generated an unprecedented and long-lived golden age of literature and art. It also gave rise to a cornucopia of transformative innovations and groundbreaking technology, particularly following the dawn of the Common Era.

The KGB is one of the most famous abbreviations of the 20th century, and it has become synonymous with the shadowy and often violent actions of the Soviet Union’s secret police and internal security agencies. In fact, it is often used to refer to the Soviet state security agencies throughout its history, from the inception of the inception of the Cheka (Extraordinary Commission) in 1917 to the official elimination of the KGB in 1992.

From about 3400-2600 BCE, the Yamnaya culture stretched from southeastern Europe into central Asia, greatly affecting other contemporary cultures in Europe and the Near East. The hallmarks of Yamnaya culture adopted by other cultures in the Near East and Europe include the use of metal tools and weapons.

On the morning of January 28, 1986, the Space Shuttle Challenger launched for the 10th time, beginning mission STS-51-L. Space shuttles had already successfully completed 24 missions, and no American spacecraft had ever failed to reach orbit during an official mission.
