[Q]: Though prehistoric remains from the Paleolithic, Neolithic, and Bronze Ages have been unearthed in the Manzanares Valley, prior to Madrid's sudden elevation to capital city in 1561 its history was rather undistinguished. Over a period of many centuries crucial in Spanish history, Madrid's significance was negligible. The Romans built their most advanced outpost on the Iberian peninsula, but left nothing of consequence in Madrid. Armies of North African nomads, intent on disseminating Islam, invaded the peninsula in a.d. Within 10 years, they had overrun most of Spain. If Madrid played any role in these pivotal events, no record of it remains. The first solid references to this obscure settlement on the Castilian plateau, guarded by the looming Guadarrama mountain range, appear in the 9th century. The Arabic name for "place of many springs," variously recorded as Magerit, Mayrit or Magrit, eventually evolved into Madrid. The hamlet entered historical chronicles for its military significance; it was located near the main line of resistance to the Christian reconquest. Over centuries of struggle, the defending Moorish army built a full-scale fort, or Alcázar, on the heights of Madrid commanding the Manzanares valley. After several unsuccessful skirmishes, the Christian forces of Alfonso VI captured Madrid in 1083. The Alcázar became a fort of the crown of Castile. During a counter-offensive in 1109, the town was overrun by the Moors, but the Christianized fortress held. The Moors were expelled from the town, but they remained in control of southern Spain for almost four centuries. Meanwhile, Madrid enjoyed brief prominence in 1308 when king Ferdinand IV and his Cortes, an early version of parliament, held a formal meeting in the fledgling town. From then on, the kings of Spain began to visit Madrid, where the air was invigorating and the hunting excellent. Ferdinand and Isabella, the Catholic monarchs that united all the provinces of Spain, first visited Madrid in 1477. <sep>Why did kings of Spain visit Madrid?<sep>Women
[A]: No


[Q]: In the rest of the world, China's supreme sage, Kongfuzi (K'ung Fu-tzu), is better known by the romanized name "Confucius." He was born in 551 b.c. in what is now Shandong Province in eastern China. So profound was his influence that eleven Chinese emperors made pilgrimages to the birthplace of the Great Teacher. You, too, can pay your respects at the vast temple raised on the site of his home in the small town of Qufu (Chufu), and at his tomb in the woods just to the north. The classics of Confucius, while seldom addressing spiritual and metaphysical matters, set standards for social and political conduct that still underlie many of the Chinese ways of doing and perceiving. Confucius laid great stress on the proper and harmonious relationships between ruler and subject, parent and child, teacher and student, the individual and the state. These relationships were deemed to be hierarchical and dictatorial. If the order was disturbed, dire consequences inevitably resulted. The son who disobeyed the father would bring disaster upon himself and his family, just as the emperor who defied the "mandate of heaven" or ignored the good of the empire brought ruin upon the nation. Over the centuries Confucius has suffered more changes of fortune than probably any other philosopher. Honored soon after his death as the greatest of scholars, he was later revered as semi-divine; you can still visit temples to Confucius in many Chinese cities. During the Cultural Revolution (1966–1976), however, he was denounced as a counter-revolutionary force. It was only after the death of Chairman Mao (1976) and the opening of China to the outside world under more progressive reformers that Confucius, too, was "rehabilitated." Unlike Confucius, about whose life many specific and even colorful details are known, the philosopher Laozi (Lao Tse or Lao-Tzu) is an enigma. Estimates of his date of birth vary by well over a century. One legend even says he taught the young Confucius. Laozi is immortalized by his book of thoughts on man, nature, and the universe, Daodejing ("The Way and Its Power"), which became the major text of China's greatest indigenous religion, Daoism (Taoism). With its emphasis on nature, intuition, the individual, paradox ("The knowledge which is not knowledge"), and the cosmic flow known as "The Way," Daoism became the religion of artists and philosophers. After the death of Confucius, the Zhou Dynasty entered a period of strife known as the "Warring States" period (475–221 b.c.). <sep>Do we know the exact date of Laozi's birth?<sep>Yes
[A]: No
