Survey the world in AD 1000 and see that China was the most vibrant, open and technologically advanced civilization. Islam, less than 400 years old, had become the most far reaching civilization in trade and travel. Cordoba, in Southern Spain, was one of the most important cities in the world. India, rich in natural resources, was the only other civilization that the Chinese respected. Enriched by contact with China, Japan looked promising but turned increasingly in on itself. We are able to examine life in the imperial palace through an intimate diary left by Sei Shonagon, who was a lady in waiting to the Heian royalty. Christianity was divided into two rival camps. The Western Catholic Church looked to Rome, the Eastern Orthodox Church looked to Constantinople. In 1054, the political wrangling reached a climax when the Pope excommunicated the Eastern Church.

All over the world people challenged nature and a century of ambitious building began. At Pueblo Bonito, in the American Southwest, a monumental city rose from the desert. Vast new churches arose all over Northern Europe to celebrate God's glory through Gothic architecture. Spectacular Christian churches were carved out of solid rock in Ethiopia to establish the power of King Lalibela. New cities produced a new way of life in Italy. Citizens gave themselves charters, established their rights, and declared themselves independent republics. Not everyone built. Nomadic tribes such as the Australian aborigines continued to flourish by hunting, gathering and honoring the land.

Genghis Khan and his Mongol horsemen thundered across Asia, creating the largest empire the world has ever known. The Mongols were ferocious warriors, but they imposed peace on the lands they conquered. It became possible to travel and trade safely from Europe to the Orient. Grandson of Genghis, Kublai Khan conquered and united the whole of China but was seduced by luxury in his palace at Xanadu. The Mongol advance west was finally halted by the Mamelukes, a Muslim dynasty of former slaves who made Cairo into one of the world's greatest cities. Goods and ideas from the Orient traveled via Venice up into northern Europe.

Black Death, the catastrophic plague that invaded Europe from the East, cut short the new prosperity. Treatment varied from the magical to the scientific. In Cairo, the number of deaths was said to reach 21.000 a day. While the great empires were devastated, smaller ones flourished. Mali, in west Africa, became wealthy through trading gold and salt. In Central Asia, Timur, a Turk born near Samarqand, rose from sheep-stealer to conqueror and creator of a vast empire that gave the world some of its most spectacular Islamic architecture. Seaborne trade prospered, especially at the eastern end of the Indian Ocean. In East Java, the Kingdom of Majapahit thrived under the splendid rule of Hayan Wuruk. Europe also suffered other catastrophes - terrible famine and a mini ice age. Across Europe, there was a call for greater equality between people and their rulers.

China set out to dominate the seas. These new trade ventures were extremely lucrative, but after 30 years Ming bureaucrats forbade further voyages and abandoned maritime imperialism. Europe was torn by civil war, but the city states of northern Italy produced a cultural explosion known as the Renaissance. The Medici prince, Lorenzo the Magnificent, dominated and adorned Florence, nurturing painting, sculpture, poetry, music, and architecture. Greater than any European city was the Tenochtitlan, the Aztec capital on the site of what is now Mexico City. Built on marshland in Lake Texcoco, the highly organized city was supported by trade over huge distances, the Aztec gods placated by mass human sacrifice. The Ottomans took advantage of the weakness of the Byzantine empire, conquered Constantinople, and turned it into the capital of their empire. Mehmed the Conqueror's palace included a harem for 2.000 women, stables for 4.000 horses, 10 mosques, 14 baths and two hospitals. The kitchen could feed 5.000 or 10.000 on holidays. There were many great voyages of the 15th Century including that of Vasco de Gama's discovery of a route to the Indian Ocean and Christopher Columbus crossing the Atlantic and back.

This was a century when the empires and religions of the world expanded aggressively. Diego de Landa, a Spanish missionary, converted thousands of Mayans in Yucatan, torturing them brutally when they continued to honor their former idols in secret. The biggest land gain was made by Ivan the Terrible, who extended Muscovite rule from the Baltic to Siberia. For every conquest, there were many failures. In Japan, a ferocious military dictator, Hideyoshi, dreamed of conquering the world, beginning with Korea and China. But the Koreans defeated him, with "turtle" ships covered with iron spikes and breathing cannon fire through dragon's head prows. Muslim conquests were even more spectacular. Akbar conquered northern India and created the sophisticated Moghul empire. In Europe, people were fascinated by strange objects brought back from exotic corners of the world. Cabinets of Curiosities, containing objects as diverse as a lock of hair from Petrus Gonsalvus, the Hairy Man of Tenerife, to fossils and souvenirs of exotic animals, were displayed by famous collectors such as Emperor Rudolf II of Prague.

The role of the scientist changed dramatically. Greatest of all the new gentlemen scientists was Isaac Newton, whose experiments with the laws of nature were undertaken to reveal God, not to disprove his existence. Colonies were established along America's Atlantic coasts. The first, in Jamestown, Virginia, struggled to survive until the tobacco trade made it viable. Slaves were transported from Africa to service new colonies. The largest numbers were taken to Brazil by the Portuguese and Dutch, their short, brutal lives eked out on the sugar plantations. In Europe the economic center of gravity shifted north. The Dutch became rich on the South East Asian spice trade and Amsterdam began a golden age. Women entered business and great painters such as Rembrandt and Vermeer were commissioned by the emerging middle class. Europe began to eclipse Arabic and Chinese eminence in science. Visiting Jesuits proved to the Emperor in China that their knowledge of astronomy was more accurate than that of the Chinese.

People began to think about politics and society in new ways. Lisbon was destroyed by an earthquake and rebuilt following rational and human ideals now known as Enlightenment. The American War and the French Revolution transformed Europe and North America. India's wealth of natural resources brought mass production of cotton, tea and silk but British Imperialism claimed her riches. China also prospered, colonizing new territories to the north and west.
