He was the first emperor of one of the greatest empires ever known to man. He commanded unmatched authority in the ancient world and was always one step ahead of his opponents. He had an intellect and a sharp wit that could cut down his foes just as easily as the steel of his sword. The life of Octavian - later known as Augustus - was rich and full. Although he lived and died over 2,000 years ago, this founder of the Roman Empire is as intriguing as ever.

Catherine the Great is one of the most influential rulers in Russian history. Though born in Prussia, she endeavored to gain the throne of Russia and went on to be the longest-ruling empress in Russian history. She ruled as an enlightened despot, promoting the principles of the European Enlightenment as she sought to modernize her beloved country. She reformed the educational system of Russia, creating a national system that utilized modern educational theory in a co-educational setting.

Constantine the Great was one of the most pivotal figures in the history of the Roman Empire and the widespread expansion of the Christian religion. This is in no way an understatement; Constantine was not only one of the last truly powerful Roman emperors, but he also successfully reconstituted the whole empire according to his vision of Rome’s future. He played the most significant role in transforming the Empire from a Greco-Roman pagan dominion into a bulwark of the Christian faith, granting for the first time real temporal power for the early Christian church.

The Mongol Empire, founded by Genghis Khan and continued by his heirs, was one of the largest and most powerful the world has ever seen. Modern China was created from the remnants of the Mongol Empire, and at its peak, this empire controlled one-sixth of the total landmass of the world. Even today, it is estimated that one in every 200 people in the world carries the DNA of Genghis Khan. The world would never be quite the same after the relatively brief reign of Genghis Khan, his children, and grandchildren.

Many of the city-states of Ancient Greece gave the world a legacy rich in art, literature, poetry, philosophy, and science. But one such state distinguished itself by embracing something very different: a warrior lifestyle, a denial of luxury and wealth, and a focus on the collective rather than the individual. While most other Ancient Greek city-states have been forgotten, the name of that city remains in use in the English language today, meaning austere or rigorous: Spartan.

World War I, or the Great War, was believed to be "the war to end all wars". Because of the incredible extent of destruction and the staggering number of wounded and dead, even those who lived through it could scarcely comprehend its horror. Beginning in 1914, alliances between powerful nations soon plunged the world into a global conflict. Fighting - including miserable trench warfare - broke out in practically every corner of Europe and spread around the world to Africa, Asia, and the Middle East.

A little over 2000 years ago a man named Julius Caesar changed the world. Even if you have never heard of him, his lasting legacy has no doubt had an impact on your life. Even the very calendar that you use is based upon the system he created, with the month of July bearing his name. So who was this man that single-handedly changed the course of history? This audiobook follows the life and legacy of the man whose life stood between Republic and Empire.

The cave dwellers of the Stone Age were brutish and primitive compared to the human civilizations that would follow. Their technological developments were limited, and their society and culture provided few lasting legacies. Until surprisingly recently, this was the general view of the period of prehistory known as the Stone Age, an age that lasted for over 2 million years and ended only around 5,000 years ago.

Alan Turing had a radical and ingenious mind. He is considered one of the fathers of artificial intelligence, and his theories on this matter range from purely mechanical to almost spiritual. During World War II, his decryption of the Nazis’ Enigma codes proved vital for the Allied victory over the Axis powers. Turing’s fingerprints are everywhere, and yet his own country for quite some time failed to acknowledge it.

The Roman Catholic Inquisition was one of the most controversial organizations in human history. Although it has been painted in a negative light, the Inquisition was too broad in scope to define as simply good or bad. It was a period where conflict and bloodshed were inevitable. It was a time where war, famine, plague, and poverty were common factors of human life. From the 1180s to the 1830s, the Inquisition was the judicial arm of the Catholic Church. Created to root out and punish heretics within the Catholic faith, the Inquisition became an institution that would carve its name into history.

In the midst of World War I, the Easter Rising took place in Dublin and throughout Ireland in April 1916. The revolutionary movement faced many problems from the beginning, including splintered leadership, disorganized support, opposition from moderate supporters of home rule, and prepared retaliation from the British.  

Alexander the Great. A boy, groomed for greatness from the earliest age, who would put his stamp on the world for generations to come. A man who sought immortality and achieved it in just 10 years. A soldier whose genius for strategy and tactics is still studied in the modern world. A ruler who understood how to win the hearts and minds of his subjects. This is the story of a Titan of the ancient world, a man who rose but, though he died, never truly fell.

Rome is a city of myth and legend. The Eternal City, the city of the seven hills, the sacred city, the caput mundi, the center of the world, Roma, Rome, by any of her many names is a city built of history and blood, marble and water, war and conquest. From legendary beginnings, a city rose from the swamp surrounded by the seven hills and split by the Tiber River. Built and rebuilt, a sacred republic and a divine empire, blessed by a thousand gods and by One, the story of her rise and fall has been told and retold for a thousand years and is still relevant in today's world, as echoes of her ancient glory have shaped our culture, laws, lifestyle, and beliefs in subtle and pervasive ways.

Beginning with the birth of the nation, slavery divided and caused conflict for the United States of America, worsening during the country's early decades as the practice became more economically vital. Finally, in 1861, the American Civil War erupted after the election of President Abraham Lincoln. Never acknowledging the South’s right to secede, Lincoln and the North fought the South through four long, bloody, destructive years; much longer than anyone thought the war would last. 

Creativity is in our bones. It is found in our very DNA, something not known to Leonardo da Vinci or anyone else who lived in his day and time. All he did was to uncover the hidden genius which lay within himself, and he used that inner genius to the very best of his abilities. Leonardo da Vinci is best known for some of the world's most masterful paintings, but he was so much more than merely another artist with paints and brushes. Born to a peasant woman in 1452, Leonardo would go on to astound the world he lived in with his artistry and his inventions.
