The Chinese are militaristic and industrious. They start the game with Warrior Code and Masonry and build riders instead of normal knights. Despite political and social upheavals that frequently ravaged the country, China is unique for its longevity and resilience as a politico-cultural entity. Most of China's cultural progress has been accomplished with relatively little outside influence; even when the country was ruled by such "barbarian" peoples as the Chin or Mongols, these were soon absorbed into the fabric of Chinese culture. The casting of bronze and the development of an alphabet date from the period of the Shang dynasty - China's first, believed to have dominated north China from the mid-16th to mid-11th century BC. The overthrow of the Shang dynasty by the Chou (1111-255 BC) spanned three generations; although the vibrant Chou culture produced some of history's greatest philosophers and artists, among them Confucius and Lao-zi, it was eventually supplanted by a "barbarian" invasion that established the brief Ch'in Empire (221-206 BC). The subsequent Han dynasty was founded by Liu Pang, who assumed the title of emperor in 202 BC. The four centuries of the Han was one of considerable changes in imperial, political, cultural and social development, as well as massive engineering projects (including the Great Wall), and established a Chinese identity that would survive until the advent of Communism. By the end of the 2nd century AD the Han Empire had virtually ceased to exist, followed by a lengthy period of rival kingdoms that did not end until 618 AD, when the T'ang dynasty came to power. The T'ang were followed by the Sung dynasties (960-1279 AD), which collapsed in the face of the Mongol invasions. By securing the allegiance of the Hsi Hsia in Tibet (1209), Genghis Khan disposed of a potential enemy and prepared the ground for an invasion of China. For several years Mongol armies pillaged the country; finally, in 1214 Genghis overwhelmed the capital of the northern Chin (modern Beijing). During the next decades there was an uneasy truce between the Mongols in the north and the Sung state in the south. The Mongols resumed their advance in 1250 under Kublai Khan, grandson of Genghis. >From 1267 onward, the Mongols, this time assisted by the armored horsemen Riders and auxiliary troops of north China,
