The Battle of Stalingrad, perceived by historians as the most important battle of World War II and regarded by Russians as the most significant battle in their country’s history, cannot be viewed solely as a military engagement between two powerful, long-time foes. Stalingrad was a battle between the Allies and the Axis Powers; it was a struggle between the Soviet Union and Germany for victory; and it was also a test of wills between Josef Stalin and Adolf Hitler.

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.

The struggle to combat the Nazis during World War II encompassed front lines far beyond conventional battlefields. In a panoramic and compelling account, author Jerry Borrowman shares seven largely untold stories of people who undertook extraordinary efforts to defeat the Third Reich at enormous personal risk.

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.

D-Day, June 6, is one of the most significant dates in the calendar. The 20th century's fate hung in the balance as Nazi Germany had marched across Europe, bringing the blitzkrieg, the Holocaust, and the mad dreams of Adolf Hitler across the bloodied landscape of Europe. In order for the Nazis to be stopped, the Allies had to invade occupied Europe. And invade they did, launching the most massive amphibious landing the world had ever seen.

The Sumerians settled in the area known as Mesopotamia, between the Tigris and Euphrates Rivers, around 5,000 years ago. They produced many fundamental changes to the way in which human societies developed - these were the first city-builders, the first people to use wheeled vehicles, the first methodical astronomers, and the first people to develop a sophisticated written language. The Sumerians also produced art, music, and literature as well as created some of the first professional soldiers the world had ever seen.

The first female Doctor of the Church, Teresa of Ávila, was a visionary who took matters of reform into her own hands. Even when the church authorities came against her, she stood her ground and held fast to her convictions. In so doing, she managed to persuade the Catholic powers to come around to her point of view. Teresa was not someone who took “no” for an answer; she charted her own course in life.

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.

Rosalind Franklin was what can only be called an overlooked genius. Although she was not fully credited for the feat at the time, her work led to major breakthroughs in our understanding of DNA. In fact, she took the first X-ray photo of DNA in all of its double helix glory. By the time her former colleagues were being showered with accolades for results they made at least partially based on her findings, Franklin would not be around to see it. Sadly, it’s believed that her use of X-ray equipment gave her terminal cancer, cutting her life short at age 37.

The Great Depression was one of the most trying eras in American history. All aspects of the US were affected. After the stock market crash of 1929, the nation was thrust into a decade of turmoil and change - in government, the economy, and culture. Many of the changes brought about by the Great Depression remain today.

Cyrus II of Persia was one of the greatest leaders that the world had ever known, he was the one in whose footsteps other empire builders would follow. From Alexander the Great to countless Roman emperors and Ottoman sultans - it was the mighty shoes of Cyrus that they all attempted to fill.More than merely a successful conqueror, Cyrus the Great is known just as much for being a great liberator as he is known for his conquests. He was even credited in the Bible as the one who freed the Jews from their long-held Babylonian exile.

During the late years of the 18th century, the spirit of Enlightenment thinking and revolution were in the air. The world was changing, moving away from ingrained beliefs about religion, reason, society, and the rights of the individual and turning more toward the laws of nature as interpreted by the scientific method. Nowhere was the influence of this radical new way of thinking more apparent than in France, and the upheaval this caused would come to bloody fruition in the form of revolution.

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.

This book tells the story of the temperance movement in America, of its rise over a period of 100 years to encompass the growing women’s movement, and how it eventually attained its goal in 1920.

Until surprisingly recently, most history books noted that America was discovered in 1492 by Christopher Columbus. The truth was that by the time that Columbus arrived in America, people had been living there for more than 12,000 years. This is the story of the gradual rise, sudden destruction, and slow recovery of the native people of North America.
