At the peak of its power, Rome's span was vast.

And it stood for almost 700 years.In this series of 48 spirited lectures, you'll see how a small village of shepherds and farmers rose to tower over the civilized world of its day and left a permanent mark on history. In telling Rome's riveting story, Professor Fagan draws on a wealth of primary and secondary sources, including recent historical and archaeological scholarship, to introduce the fascinating tale of Rome's rise and decline, including the famous events and personalities that have become so familiar: .

Sophisticated beyond the Spaniards' wildest imaginings, these people were the Aztecs, the Maya, and related cultures that shared common traditions of religion, government, the arts, engineering, and trade. In many ways more advanced than European nations, these societies equaled the world's greatest civilizations of their time.

Mesopotamia is the ancient name for the region that is now Iraq, a remarkably advanced civilization that flourished for two-thirds of the time that civilization has existed on Earth. Mesopotamians mastered irrigation agriculture; built the first complex urban societies; developed writing, literature, and law; and united vast regions through warfare and diplomacy. While civilizations like Greece and Rome have an unbroken tradition of written histories, the rich history of Mesopotamia has only been recently rediscovered, thanks to the decipherment of Mesopotamia's cuneiform writing less than 200 years ago.

The Roman Republic is one of the most breathtaking civilizations in world history. Between roughly 500 BCE to the turn of the millennium, a modest city-state developed an innovative system of government and expanded into far-flung territories across Europe, Northern Africa, and the Middle East. This powerful civilization inspired America's founding fathers, gifted us a blueprint for amazing engineering innovations, left a vital trove of myths, and has inspired the human imagination for 2,000 years.
