La historia de Alemania Oriental estuvo estrechamente ligada al desarrollo de sus servicios de seguridad, concretamente de la Stasi. En una época de países totalitarios dominados por agencias estatales represivas, la Stasi se destacaba por su tamaño y por la amplitud y profundidad de su vigilancia. Películas como Das Leben der Anderen (“La vida de los otros”) encapsulaban actitudes y concepciones posteriores a la unificación, tanto de la vida en Alemania Oriental como de las actividades de la Stasi.

Cuando la gente piensa en objetos voladores no identificados (OVNIS), tiende a pensar en discos voladores pilotados por seres grises con grandes cabezas y enormes ojos. Tienden a pensar que estos avistamientos apenas comenzaron hace relativamente poco tiempo y que la creencia en los OVNIs es una especie de religión moderna provocada, quizás, por los temores justificados de una era nuclear. Pero un estudio del fenómeno revela rápidamente que la humanidad ha estado viendo OVNIS desde el principio de la historia registrada y quizás mucho más tiempo que eso.

El surgimiento de sociedades secretas ha sido siempre una de las facetas más fascinantes de la civilización, un fenómeno que ha estado presente desde el nacimiento de la humanidad. Incluso siglos después de ser fundadas, algunas de ellas continúan siendo bien conocidas, como la sociedad de los Caballeros Templarios, un grupo de guerreros armados que procedían de Tierra Santa.

Yugoslavia was arguably one of the most unusual geopolitical creations of the 20th century. The Yugoslav state had never existed in any historical sense, and the ties that bound together its constituent peoples were tenuous at best. Although nominally all “Slavs,” the country was an amalgamation of languages, alphabets, cultures, religions, and traditions, which ensured its short existence was littered with splits, conflicts, and shocking violence. In a sense, it’s somewhat surprising that it lasted as long as it did.

Though it might be hard to believe, the Americans did not have a covert operations organization when they joined the war, and like the British, it took them some time to realize it could be a powerful tool. As a result, the Office of Strategic Services (OSS) was not established until June 13, 1942, six months after the attack on Pearl Harbor. And of course, it would all chart a path for the early days of America’s most famous intelligence agency, the CIA.

The vast expanses of southern Russia and the Ukraine provided the Eastern Front arena where the armies of Third Reich dictator Adolf Hitler and Soviet dictator Josef Stalin wrestled lethally for supremacy in 1943. Endless rolling plains - ideal "tank country" - vast forests, sprawling cities, and enormous tracts of agricultural land formed the environment over which millions of men and thousands of the era's most formidable military vehicles fought for their respective overlords and ideologies.

The world is filled with mysteries, and even in the modern age, much of the planet remains unexplored. The depths of the oceans and the intricate and extensive cave systems that honeycomb some parts of the Earth are still largely unknown. Thus, it should come as no surprise that when it comes to this terra incognita, people have projected all sorts of ideas. Tales of sunken cities or lost civilizations are just some of the fanciful theories, and those could even be considered tame in comparison to the idea that Earth is flat.

Naval combat underwent a significant metamorphosis during World War II. Nazi Germany and Imperial Japan launched some of the most powerful battleships ever to sail the world's oceans, yet the conflict witnessed the emergence and triumph of the aircraft carrier as the 20th century's true monarch of the seas. Submarine warfare expanded and developed while aircraft technology and doctrine experienced several revolutionary changes due to the unforgiving demands of the new combat environment.

Submarine warfare began tentatively during the American Civil War. Robert Whitehead's invention of the torpedo introduced the weapon later used most frequently by submarines. World War I proved the value of submarines, ensuring their widespread employment in the next conflict. Submarine Warfare in World War I: The History and Legacy of the German U-boats and Allied Efforts to Counter Them analyzes the underwater fighting. You will learn about submarine warfare in World War I like never before.

The most iconic images of the First World War are of the war on land. But part of that same generation faced a very different war, one that was just as important in deciding the fate of Europe. This was the war at sea. Here, events took place that would draw America into the war, providing the Allies with a new pool of manpower and so ensuring that the scales of the conflict tipped in their favor. At sea just as much as on land, this was a war that would shape the future of the world.

It has long been a maxim that it is easy to forget when one is at war who the enemy really is, and that can certainly be said for the Ebola virus, which recently catapulted into headlines and instantly became the most feared disease in the world. In the case of the fight against Ebola, the enemy is not the person who has contracted the disease, nor is it the region where the virus has flourished. The enemy is a microscopic virus that, when seen under sufficient magnification, looks like a piece of loosely knotted rope.

German South West Africa: The History and Legacy of Germany’s Biggest African Colony chronicles the politics and conflicts that marked Germany’s efforts to colonize German South West Africa. You will learn about German South West Africa like never before.

Although he is unquestionably one of the most studied leaders of the 19th century, Simón Bolívar remains today as enigmatic as he was two centuries ago, when his vision and presence largely inspired the overthrow of the Spanish Empire in the New World.

Durante la Guerra de los Seis Días en 1967, las fuerzas israelíes atacaron repentinamente el Sinaí en respuesta a la violación por parte de Egipto de un tratado anterior que permitía el paso de barcos israelíes a través del importante Estrecho de Tirán. En una campaña relámpago, las fuerzas israelíes bien entrenadas y bien dirigidas, equipadas con vehículos y aviones americanos y franceses, destrozaron decisivamente a las fuerzas armadas egipcias de baja calidad. Cuando Jordania y Siria atacaron a Israel en apoyo de Egipto, los israelíes también aplastaron sus fuerzas.

Pavlov's dogs are to Psychology 101 what Rome is to antiquity classes. This particular series of experiments and the concept of classical conditioning likely ring a bell for many readers and listeners because they have been referenced in countless texts, both scientific and otherwise, and they have seeped into various forms of pop culture throughout the years.

The modern history of Africa was, until very recently, written on behalf of the indigenous races by the white man, who had forcefully entered the continent during a particularly hubristic and dynamic phase of European history. In 1884, Prince Otto von Bismarck, the German chancellor, brought the plenipotentiaries of all major powers of Europe together, to deal with Africa's colonization in such a manner as to avoid provocation of war. This event - known as the Berlin Conference of 1884-1885 - galvanized a phenomenon that came to be known as the Scramble for Africa.

The Wright Brothers initially underestimated the difficulties involved in flying, and they were apparently surprised by the fact that so many others were working on solving the “problem of human flight” already. Decades before their own historic plane would end up in the National Air & Space Museum, Wilbur and Orville asked the Smithsonian for reading materials and brushed up on everything from the works of their contemporaries to Leonardo Da Vinci.

While not dead, radio's familiarity has made it seem a bit mundane, but people shouldn’t think of it that way. In fact, the airwaves have always been a place of mystery, a battleground of competing ideologies, and a source of anonymous voices. Radio has been used to support war efforts, topple governments, communicate secretly, and even attempt to communicate with the dead. These strange stories will make this familiar medium seem a bit less familiar and far more interesting.

During the Revolution, relatively little consideration had been given to the role of the federal government in the new nation, and the precise role and authority of an overarching entity with responsibility for all states within the union was a major problem. One of the most urgent tasks Washington faced was the establishment of a treasury to oversee the finances of America and regulate its currency. The Panic of 1792 examines the origins of America’s financial system, and how it was disastrously affected so shortly after the Constitution was ratified.

The question of man’s place in the extended universe has been pondered by every known culture since the beginning of recorded history. Naturally, as technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. While incidents like the one at Roswell led to conspiracies and a craze among those who insisted the government was hiding proof of extraterrestrials’ existence, governments across the world were actually secretly studying UFO sightings by the mid-20th century.
