This book traces the history of the ancient Khazar Empire, a major but almost forgotten power in Eastern Europe, which in the Dark Ages became converted to Judaism. Khazaria was finally wiped out by the forces of Genghis Khan, but evidence indicates that the Khazars themselves migrated to Poland and formed the cradle of Western Jewry. To the general reader the Khazars, who flourished from the 7th to 11th century, may seem infinitely remote today. Yet they have a close and unexpected bearing on our world, which emerges as Koestler recounts the fascinating history of the ancient Khazar Empire. At about the time that Charlemagne was Emperor in the West. The Khazars' sway extended from the Black Sea to the Caspian, from the Caucasus to the Volga, and they were instrumental in stopping the Muslim onslaught against Byzantium, the eastern jaw of the gigantic pincer movement that in the West swept across northern Africa and into Spain. Thereafter the Khazars found themselves in a precarious position between the two major world powers: the Eastern Roman Empire in Byzantium and the triumphant followers of Mohammed. As Koestler points out, the Khazars were the Third World of their day. They chose a surprising method of resisting both the Western pressure to become Christian and the Eastern to adopt Islam. Rejecting both, they converted to Judaism. Mr Koestler speculates about the ultimate faith of the Khazars and their impact on the racial composition and social heritage of modern Jewry. He produces a large body of meticulously detailed research.

"The Khazars (Turkish: Hazarlar) were a semi-nomadic Turkic people who created one of the largest states of medieval Eurasia, Khazaria, with its capital at Atil. Astride one of the major arteries of commerce between northern Europe and southwestern Asia, Khazaria commanded the western marches of the Silk Road and played a key commercial role as a crossroad between China, the Middle East, and Europe."--Wikipedia.

The Khazars were one of the most important Turkic peoples in European history, dominating vast areas of southeastern Europe and the western reaches of the Central Asian steppes from the 4th to the 11th centuries AD. They were also unique in that their aristocratic and military elites converted to Judaism, creating what would be territorially the largest Jewish-ruled state in world history. They became significant allies of the Byzantine Empire, blocking the advance of Islam north of the Caucasus Mountains for several hundred years. They also achieved a remarkable level of metal-working technology, and their military elite wore forms of iron plate armour that would not be seen in Western Europe until the 14th century. The Khazar state provided the foundations upon which medieval Russia and modern Ukraine were built. Fully illustrated with detailed colour plates, this is a fascinating study into the armies, organisation, armour, weapons and fortifications of the Khazars.

The Jews of Khazaria chronicles the history of the Khazars, a people who, in the early Middle Ages, founded a large empire in eastern Europe (located in present-day Ukraine and Russia). The Khazars played a pivotal role in world history. Khazaria was one of the largest-sized political formations of its time, an economic and cultural superpower connected to several important trade routes. It was especially notable for its religious tolerance, and in the 9th century, a large portion of the royal family converted to Judaism. Many of the nobles and commoners did likewise shortly thereafter. After their conversion, the Khazars were ruled by a succession of Jewish kings that began to adopt the hallmarks of Jewish civilization, including the Torah and Talmud, the Hebrew script, and the observance of Jewish holidays. In this thoroughly revised edition of a modern classic, The Jews of Khazaria explores many exciting new discoveries about the Khazars' religious life, economy, military, government, and culture. It builds upon new studies of the Khazars, evaluating and incorporating recent theories, along with new documentary and archaeological findings. The book gives a comprehensive accounting of the cities, towns, and fortresses of Khazaria, and features a timeline summarizing key events in Khazar history.

A historical tour de force, The Invention of the Jewish People offers a groundbreaking account of Jewish and Israeli history. Exploding the myth that there was a forced Jewish exile in the first century at the hands of the Romans, Israeli historian Shlomo Sand argues that most modern Jews descend from converts, whose native lands were scattered across the Middle East and Eastern Europe. In this iconoclastic work, which spent nineteen weeks on the Israeli bestseller list and won the coveted Aujourd'hui Award in France, Sand provides the intellectual foundations for a new vision of Israel's future.

Where do East European Jews – about 90 percent of Ashkenazi Jewry – descend from? This book conveys new insights into a century-old controversy. Jits van Straten argues that there is no evidence for the most common assumption that German Jews fled en masse to Eastern Europe to constitute East European Jewry. Dealing with another much debated theory, van Straten points to the fact that there is no way to identify the descendants of the Khazars in the Ashkenazi population. Using a multidisciplinary approach, the author draws heavily on demographic findings which are vital to evaluate the conclusions of modern DNA research. Finally, it is suggested that East European Jews are mainly descendants of Ukrainians and Belarussians. UPDATE: The article “The origin of East European Ashkenazim via a southern route” (Aschkenas 2017; 27(1): 239-270) is intended to clarify the origin of East European Jewry between roughly 300 BCE and 1000 CE. It is a supplement to this book.
