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.

Though it was one of the most advanced civilizations of its time and responsible for the most ancient prehistoric urban sites across the Indian subcontinent, the Indus Valley Civilization was forgotten for millennia, until 20th century archaeologists rediscovered and began excavations at Mohenjo-daro and Harappa.

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.

La guerra siempre ha tenido como resultado a prisioneros. En la antigüedad, muchos fueron convertidos en esclavos por los ejércitos victoriosos, mientras que en la Europa medieval, a menudo eran devueltos a sus familias a cambio de un rescate, lo cual llevaba a la fortuna o a la pobreza dependiendo del bando en el que se encontraba.

Wovoka (1867-1932), the Ghost Dance Prophet, was a member of the Walker River band of Paiutes in Western Nevada. The Walker River Reservation was established in 1859, and was Wokova’s home off and on for years. Wovoka was also known as Jack Wilson, a name he acquired while he was, for some years, employed on the David Wilson family ranch in the Mason Valley.

Durante los varios siglos en que el antiguo Egipto se irguió como una de las más grandes civilizaciones, si no la más grande, del mundo antiguo, los conflictos con sus enemigos jugaban a menudo un rol central en textos jeroglíficos y arte de los templos y tumbas....

Venerado por muchas culturas, el «Señor del espejo humeante», uno de los dioses principales del gran Imperio azteca, es también una de las deidades mesoamericanas más interesantes, y a la vez difíciles de entender. Conductor de los destinos del mundo, dador y despojador, patrón de reyes y de esclavos, sembrador de discordias y revelador de pecados, señor de la noche y la oscuridad, primer sol de la creación.

Dicen que el juicio no existe en Lourdes. Una vez que uno pone un pie en este suelo sagrado, todas las barreras de raza, condición social, antecedentes y diferencias de religión dejan de existir. No es uno más que un alma humilde en busca de la renovación de la propia conexión con Dios.

El término «moro» es un nombre más histórico que étnico. Es una invención de los cristianos europeos para referirse a los habitantes islámicos del Magreb (norte de África), Andalucía (España), Sicilia y Malta, y a veces se usaba para designar a todos los musulmanes.

Most scientists believe the evolution of humans has a history nearly as long as life itself. Anatomically modern humans and all other life that has existed on the planet first came about from the single-celled microorganisms that emerged approximately four billion years ago. Through the processes of mutation and natural selection, all forms of life developed, and this continuous lineage of life makes it difficult to say precisely when one species completely separates from another.

The current view of science is that Earth is around 4.6 billion years old, and the first 4 billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge.

The Inca Empire, which flourished in modern day Peru and along the west coast of South America, was the largest Native American empire in pre-Columbian America, until Pizarro and the Spanish conquistadores conquered them in the 16th century. What ultimately sealed their doom was the rumor that huge amounts of gold were available in regions south of the Andes Mountains.

La Navidad es la fiesta más importante del calendario internacional. Después de los respectivos días que exaltan el orgullo nacional de los países —el Día de la Independencia en Estados Unidos, el Día de la Victoria en Rusia, el Día de la Bastilla en Francia— sin duda es el 25 de diciembre el que articula la vida familiar, el trabajo y la economía de prácticamente todo el orbe… incluyendo muchos países no cristianos.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit.

La península de Yucatán, una de las pocas penínsulas del mundo en proyectarse hacia el norte fue, ya desde su formación, lugar de hechos extraordinarios. Considerada hoy como un lugar de extraordinaria belleza natural, fue descrita como “un país muy triste” por los primeros visitantes españoles.

Many ancient civilizations have influenced and inspired people in the 21st century, and the Greeks and Romans continue to fascinate the West today, but of all the world’s civilizations, none have intrigued people more than the Mayans, whose culture, astronomy, language, and mysterious disappearance all continue to captivate people. In the past decade especially, there was a renewed focus on the Maya, whose advanced calendar led many to speculate the world would end on the same date the Mayan calendar ended in 2012.

Carthage was one of the great ancient civilizations, and at its peak, the wealthy Carthaginian empire dominated the Mediterranean against the likes of Greece and Rome, with commercial enterprises and influence stretching from Spain to Turkey.

Spies are a feature of countless works of fiction in which they often discover secrets on which the fate of nations hang in the balance. Reality is generally rather more mundane as spies often gather low-level intelligence that only makes sense when it is examined by analysts and compared to information from other sources. Espionage provides clues to what the enemy is planning, but on its own it rarely changes the course of a war. Moreover, real spies are generally anonymous and not the bold, swashbuckling action heroes depicted in fiction.

Most Americans have heard of the Little Bighorn, the 1876 battle in which a band of Lakota Sioux and their allies wiped out most of the 7th US Cavalry under the command of George Armstrong Custer. The movie images are of fierce warriors in long eagle feather headdresses flowing behind them as they gallop across the plains on nimble Indian ponies.

On July 12, 1588, the legendary Spanish Armada headed for the English Channel. The Spanish plan was to take this invasion, led by the Duke of Parma, to the coast of southeast England, where they would be unleashed to conquer Elizabethan England for Spain’s King Philip II and Catholic Christendom. The Armada included over 150 ships, 8,000 sailors, and 18,000 soldiers, and it boasted a firepower of 1,500 brass guns and 1,000 iron guns. Just leaving port itself took the entire Armada two days.
