The laws and regulations in human history can be revealed by computational models.From 221 before Christ(BC)to 1912 Anno Domini(AD),the unification pattern has dominated the main part of Chinese history for 2132 years.Before the emergence of the first unified empire,the Qin Empire in 221 BC,there existed the Eastern Zhou dynasty(770 BC to 221 BC).This long dynasty has two stages,and here we focus on the first stage.This Spring-Autumn stage was from 770 BC(with 148 states)to 476 BC(with 32 states).The whole country(China)is modelled as a multi‐agent system,which contains multiple local states.They behave autonomously under certain action rules(wars and conflicts),which forms the main reason for the annexations and disappearance of most states.Key factors(power,loyalty,bellicosity and alliance)have been considered in our model settings,and simulation outcomes will be monitored and collected.Eventually,an optimal solution is obtained,which well unveils the internal mechanism and statistical features of real big history.Furthermore,counterfactuals are used to explore the non‐linear effects of the key factors,which deepens the authors’understanding of civilisa-tion evolutions in human history. 展开更多

For a very long time, the areas available for continuous long-distance trade were limited to territories of Braudel's Mediterrande (1949). Whatever the commercial organizations (merchants in the Roman or the Fatimid Empires, the Hanseatic League, the Florentine Companies) were, their trade was not able to directly handle branches more than a month's sailing from their main base (in the best conditions). During the three centuries after Vasco de Gama had reached India, European trading areas dramatically expanded to the shores of Asia, and a long period of harsh competition set the East India Companies of the main European powers of the time against one another. What were the elements that allowed these companies to maintain transactions over such vast areas? And why were some of these companies far more successful than the others? A large set of secondary sources focusing on one company or on a particular aspect of trade (Chauduri, 1978; Israel, 1989; Subrahmanyan, 1993; Ames, 1996) exist, however, none of them treat their successive successes and failures. The aim of this paper is to briefly review these sources, to extract information from them and to compare the economic adaptations and innovations that allowed these companies to be the greatest of their time. 展开更多

Why China's Western Xia tombs were destroyed--and how historians and archaeologists are bringing them back to life。In the 1930s,German pilot Wulf-Diether Graf zu Castell-Rudenhausen captured a remarkable photograph over the Helan Mountains in Ningxia,China:clusters of white conical earthen mounds rising from the desolate plain.Initially mistaking them for termite mounds,Castell-Rudenhausen published the image in his book Chinaflug,little expecting that what he had casually recorded was actually the royal necropolis of one of the most mysterious dynasties in Chinese history:the Xixia,or Western Xia. 展开更多

During the 7-9th century,the Tibetan Empire constituted a superpower between the Tang Empire and Abbasid Caliphate:one that played significant roles in geopolitics in Asia during the Early Medieval Period.The factors which led to the rise and rapid decline of this powerful Empire,the only united historical regime on the Tibetan Plateau(TP),remain unclear.Sub-annual scale precipitation and decadalscale temperature records of the central TP are presented,indicating that the height of this Empire coincided with a two-century long interval of uncharacteristically warm and humid climate.The ameliorated climate enabled the expansion of arable land and increased agricultural production.The close relationship between the precipitation records and historical events implied that the Empire implemented flexible strategies to tackle the effects of climate changes.This has implications for agricultural production in alpine regions including the TP,in the context of current global warming. 展开更多

The life cycle pattern of empires is pervasive worldwide,and this is caused by multiple factors.In the history of Vietnam,there are totally about ten empires or dynasties,which have aggregately lasted for more than one thousand years.Here,we apply the life cycle model and agent-based modeling to uncover the underlying mechanisms of the life cycle pattern for Vietnam empires.Macroscopically,the man-land relationship greatly shapes the life cycle pattern of traditional agricultural empires.The balancing process between land and population is critical for the empires.The relationship between incomes and costs has determined the actions or strategies of the social members or individuals.It suggests that our optimal solutions and simulations have perfectly matched the real history of Vietnam.Under three optimal solutions,the distributions of simulated and real empire durations in history can be well-matched,in terms of both discrete(histogram)and continuous forms(kernel density).It indicates that the history of human society is a dynamic process,which is determined by certain evolutionary rules and regulations.Therefore,we are able to back-calculate,simulate,and even predict the future of empires or countries. 展开更多

Modernization in medicine began in the Ottoman Empire in the 19^(th)century.Until that time,medical education had been provided through the traditional master-apprentice practices and its methods had relied on custom or religion.The most important of these reforms was in 1827,when the first medical schools in surgical and clinical branches were opened in Istanbul.The lack of contemporary understanding in medical education until that time had caused an underdevelopment in forensic sciences as it had in various other fields.Following the reform movements,the contents of the forensic medicine curriculum,mainly influenced by the French medical schooling,touched upon all areas of forensic sciences such as pathology,toxicology,organic chemistry,neuropsychiatry,gynecology,handwriting analysis and criminalistics.It was noteworthy to see such rapid development in scientific modernization considering the fact that,before the reform movements,the religion had a repressive effect and it was forbidden to even perform laboratory tests or examinations on corpses.In the modem Turkish Republic,founded in 1923 after World War I,scientific reforms gained momentum and began competing with the modem world.Such that,after a letter sent to the Turkish Government by Albert Einstein in 1933,the contemporary Turkish universities embraced the scientists who escaped from the Nazi regime. 展开更多

As our understanding of the Qing empire and its various borderlands has evolved, so too have we come to appreciate China's early modem commercial sophistication. In recent North American studies of the Qing, the links between commerce and conquest have come under investigation, and we are increasingly urged to pay attention to merchants and merchant capital. But how should we understand the relationship between merchants and the Qing empire in the borderlands? This article surveys selected work on the borderlands and commercialization, primarily in the Northwest and Southwest. The goal is to initiate a more comprehensive discussion of how to understand the intersection of commerce and empire while also making some suggestions for ways that borderlands history might shape future work on China. 展开更多

The Greek cities under Parthian rule inherited the legacy of local administration from the Seleucid Empire.Parthian King Mithridates I conquered the Mesopotamian region and the Iranian plateau.Due to factors such as ongoing conquests and political instability,the Greek cities were granted a special autonomous status.After the death of the Parthian king Mithridates Il,the Parthian nobility gained too much power which weakened the central authority,and intense struggles emerged between the elites and the populace within the Greek cities.The Parthian kings began to strengthen their control over the Greek cities by granting the title of“philoi” to local elites,making them the royal agent,thus establishing a relationship of trust.By efectively utilizing the Greek cities'autonomous tradition,the Parthian kings were able to flexibly adjust their relationship to these cities,which proved to be an important approach in improving local governance effectiveness. 展开更多
