Post-classical historyIn world history, post-classical history refers to the period from about 500 CE to 1500 CE, roughly corresponding to the European Middle Ages. The period is characterized by the expansion of civilizations geographically and the development of trade networks between civilizations. This period is also called the medieval era, post-antiquity era, post-ancient era, pre-modernity era, or pre-modern era.
Great DivergenceThe Great Divergence or European miracle is the socioeconomic shift in which the Western world (i.e. Western Europe and the parts of the New World where its people became the dominant populations) overcame pre-modern growth constraints and emerged during the 19th century as the most powerful and wealthy world civilizations, eclipsing previously dominant or comparable civilizations from the Middle East and Asia such as the Ottoman Empire, Mughal India, Safavid Iran, Qing China and Tokugawa Japan, among others.
Economy of the Song dynastyThe economy of the Song dynasty (960–1279) in China was the wealthiest economy in the world during its time. The dynasty moved away from the top-down command economy of the Tang dynasty (618-907) and made extensive use of market mechanisms as national income grew to be around three times that of 12th century Europe. The dynasty was beset by invasions and border pressure, lost control of North China in 1127, and fell in 1279. Yet the period saw the growth of cities, regional specialization, and a national market.
GazetteerA gazetteer is a geographical dictionary or directory used in conjunction with a map or atlas. It typically contains information concerning the geographical makeup, social statistics and physical features of a country, region, or continent. Content of a gazetteer can include a subject's location, dimensions of peaks and waterways, population, gross domestic product and literacy rate. This information is generally divided into topics with entries listed in alphabetical order.
SinocentrismSinocentrism refers to the worldview that China is the cultural, political, or economic center of the world. It may be considered analogous to Eurocentrism. Sinocentrism was a core concept in various Chinese dynasties. The Chinese considered themselves to be "all-under-Heaven", ruled by the emperor, known as Son of Heaven. Those that lived outside of the Huaxia were regarded as "barbarians". In addition, states outside of China, such as Japan or Korea, were considered to be vassals of China.
Sino-Roman relationsSino-Roman relations comprised the (primarily indirect) contacts and flows of trade goods, of information, and of occasional travellers between the Roman Empire and the Han Empire of China, as well as between the later Eastern Roman Empire and various Chinese dynasties. These empires inched progressively closer to each other in the course of the Roman expansion into the ancient Near East and of the simultaneous Han Chinese military incursions into Central Asia. Mutual awareness remained low, and firm knowledge about each other was limited.
Chinese astronomyAstronomy in China has a long history stretching from the Shang dynasty, being refined over a period of more than 3,000 years. The ancient Chinese people have identified stars from 1300 BCE, as Chinese star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the mid-Shang dynasty. The core of the "mansion" (宿 xiù) system also took shape around this period, by the time of King Wu Ding (1250–1192 BCE).
Red envelopeA red envelope or red packet () is a monetary gift given during holidays or for special occasions such as a wedding, a graduation, or the birth of a baby. Although the red envelope is from Chinese traditions, other cultures also share similar traditional customs. The red packet is also called "money warding off old age" () for Chinese New Year. These customs have also been adopted across parts of Southeast Asia, and other countries that have a sizable ethnic Chinese population as well.
IsolationismIsolationism is a political philosophy advocating a national foreign policy that opposes involvement in the political affairs, and especially the wars, of other countries. Thus, isolationism fundamentally advocates neutrality and opposes entanglement in military alliances and mutual defense pacts. In its purest form, isolationism opposes all commitments to foreign countries including treaties and trade agreements. This distinguishes isolationism from non-interventionism, which also advocates military neutrality but does not necessarily oppose international commitments and treaties in general.
ShipbuildingShipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking.
