The early history of our planet 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. The current view of science is that planet Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. The Triassic Period: The History and Legacy of the Geologic Era that Witnessed the Rise of Dinosaurs looks at the development of the era, the extinction events that preceded it, and how dinosaurs began to evolve in the Late Triassic. You will learn about the Triassic Period like never before.

The Romans were master builders, and much of what they built has stood the test of time. Throughout their vast empire, they have left grand structures, from the Forum and Pantheon in Rome, to the theatres and hippodromes of North Africa, and the triumphal gates in Anatolia and France. Wherever they went, the Romans built imposing structures to show their power and ability, and one of their most impressive constructions was built on the northernmost fringe of the empire.

A journey into the weird, wonderful and truly astonishing lives of the small but mighty creatures who keep the world turning. Out of sight, underfoot, unseen beyond fleeting scuttles or darting flights, insects occupy a hidden world yet are essential to sustaining life on earth. Insects influence our ecosystem like a ripple effect on water. They arrived when life first moved to dry land, they preceded - and survived - the dinosaurs, they outnumber the grains of sand on all the world’s beaches, and they will be here long after us.

For nearly a thousand years following its foundation, there was only one Christian church. Centered in the city of Rome, the church expanded and grew until it became the dominant religion in Europe and beyond. The early growth of the Church had been suppressed by the Romans until the Emperor Constantine became the first to convert the empire to Christianity. From that point forward, the growth of the Church was inextricably linked with the Roman Empire - the most powerful military, economic, and political force in the ancient world.

The early history of our planet 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. The current view of science is that planet Earth is around 4.6 billion years old. The first four 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.

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.

Throughout history, walls have been constructed as part of nations’ and kingdoms’ defensive structures to keep barbarian hordes, marauding rebels, and recalcitrant tribes out of defined geographic areas. The Sasanians built an impressive wall in central Asia, one that was longer than Hadrian’s Wall and by all accounts just as effective. Throughout the centuries, the Sasanian wall has gone by several different names, but it is now known as the “Great Wall of Gorgan” due to its length and location near the city of Gorgan in the modern nation-state of Iran.  

"Rome was a poem pressed into service as a city.” In that short line, Anatole Broyard, a 20th century American writer, compactly captures the timeless and enchanting beauty that resides within the Eternal City of Rome. This tourist destination is often one of the highest ranked on bucket lists, for how could one not want to experience its marvelous ruins, mirror-like rivers, and spectacular stretches of aqueducts, firsthand?

 The Magyars: The History and Legacy of the Medieval Tribes That Established the Kingdom of Hungary examines the Magyars and their culture, from their origins through the Arpad Dynasty to their raids on Europe, the establishment of a royal dynasty, and their integration into Western civilization, marking the transition from the Magyars to Hungarians. 

Africa may have given rise to the first human beings, and Egypt probably gave rise to the first great civilizations, which continue to fascinate modern societies across the globe nearly 5,000 years later. In Egypt, the first mummies seem to have been natural, but after their discovery, mummification became a time-honored tradition in this ancient civilization. The Mummies of Ancient Egypt examines the history and evolution of the Egyptians’ practices, and how the mummification process came about and was perfected; you will learn about Egyptian mummies like never before.

The success of the Five Good Emperors ironically brought about the worst plague in Rome’s epic history. Due to constant warfare on the borders and attempts to defend positions against various groups, Roman soldiers came into contact with foreign diseases, and they unwittingly brought them home when campaigns ended. This culminated around 165 CE, when an unidentified disease brought the empire to its knees and afflicted an untold number of individuals, one of whom may have been Lucius Verus, the co-emperor of Rome alongside Marcus Aurelius.

In 1938, the Soviet Union film company Mosfilm released the motion picture Alexander Nevsky, directed by Sergei Eisenstein. It is a historical drama depicting the defense of the Republic of Novgorod against an invasion of the Teutonic Knights in the mid-13th century. The eponymous hero of the story, the Prince of Novgorod, leads his troops against the German knights on a field of solid ice.

Before the scientific age, people had no knowledge of the microbiological agents - unseen bacteria and viruses - which afflicted them, and thus, the maladies were often ascribed to wrathful supernatural forces. Even when advances in knowledge posited natural causes for epidemics and pandemics, medicine struggled to deal with them, and for hundreds of years, religion continued to work hand-in-hand with medicine.

Plague and pestilence have both fascinated and terrified humanity from the very beginning. Societies and individuals have struggled to make sense of them, and more importantly, they’ve often struggled to avoid them. Before the scientific age, people had no knowledge of the microbiological agents - unseen bacteria and viruses - which afflicted them, and thus, the maladies were often ascribed to wrathful supernatural forces.
