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.

In the third century CE, as Roman leaders vied with each other for power and constantly fought civil wars, Rome’s famous roads fell into disrepair, the economy was crippled, the continent-wide trade system that had flourished in the previous years was replaced with a basic barter system, and there was a reduction in international trade. People became ever more fearful for their personal safety, and the imperial crisis saw an increasing trend toward sacrificing personal liberties and rights in return for guarantees of safety from wealthy landowners.

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.

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.

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.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras.

Mayan Astronomy: The History of the Maya’s Measurements of the Planets and Stars examines what is known and unknown about the Maya’s astronomy, and why their astronomy was among the most accurate in the world.

While the bow was used throughout ancient times and the Middle Ages, on mainland Europe it was mostly replaced by the crossbow in the early 13th century. But that would change with the introduction of the longbow; a more powerful weapon than the traditional hunting bows. The original longbowmen were Welshmen recruited by King Edward I of England after he conquered Wales, and the weapon got its name from the fact that it was almost as tall as the man using it. This gave it a longer draw and therefore more force as longbows were generally made of yew, a strong and pliable wood.

Along with Egypt, the cultural and geographic region known as Mesopotamia was home to some of the world’s earliest civilizations and also the first known form of writing, cuneiform. Many different ethnic groups vied for power in ancient Mesopotamia over the course of antiquity--spanning about 3,000 years--and many of them spoke different languages. Despite these differences, the people in Mesopotamia shared many cultural attributes including similar religious practices, a common art and architecture style, and a shared use of the cuneiform script.

In terms of geopolitics, perhaps the most seminal event of the Middle Ages was the successful Ottoman siege of Constantinople in 1453. The city had been an imperial capital as far back as the fourth century when Constantine the Great shifted the power center of the Roman Empire there effectively establishing two almost equally powerful halves of antiquity’s greatest empire. Constantinople would continue to serve as the capital of the Byzantine Empire even after the Western half of the Roman Empire collapsed in the late fifth century.

It has been famously pointed out that the Holy Roman Empire was neither holy, nor Roman, but it was also not an empire in the sense people expect when hearing the term. In theory, the emperor was the highest prince in Christendom, and his dominion extended the length and breadth of Western Europe. The empire had been created by the papacy in 801 when Pope Leo III famously crowned the supposedly unwitting Charlemagne in Saint Peter’s Basilica, intending to recreate the Western Roman Empire.

Debates over paper money and banking are older than the United States of America itself. Eighteenth and 19th century Americans were deeply ambivalent about paper money and central banks, and political fights over these issues were among the bitterest in American history. In fact, controversies over the country’s central bank birthed both the first (1792-1824) and second (1828-1852) party systems. Frequently, policymakers crafted responses to the crisis at hand, and as a result, they implemented policies that were inadequate to the challenges the country faced in the future.

Samoa is a group of about 20 islands in the South Pacific Ocean, totaling slightly over 1,100 square miles, about a fifth the size of Hawai’i. The ancestors of the Samoans arrived there many centuries ago. Archaeological artifacts suggest Polynesians arrived perhaps three thousand years before the present, or perhaps even earlier.
