Xi’an’s History


Xi'an is among the Top Four Ancient Capitals of the world, in the company of Athens, Rome and Cairo. It once functioned as the political, economic and cultural center of China and as the starting point of the Silk Road.


In China’s remote antiquity, “Lantian Ape Man” lived in its region; in the Neolithic Period, “Banpo Villagers” settled there to set up their tribes. In the year 1046 BC in the Western Zhou dynasty, Xi'an was called Fenghao, which was the combination of two cities, Fengjing and Haojing, established by the Emperor Wen and Emperor Wu of Zhou respectively. In the history of China, the two cities were the first national capitals to rule the entire state.


In the early Western Han Dynasty (206 BC- AD 220), Liu Bang established his capital in Xi'an and named it Chang'an, which means “eternal ruling and permanent peace”; from then to the late Tang dynasty (618-907) the city took the name of Chang'an.


After the Tang dynasty, Chang'an was renamed Jingzhou Prefecture during the Later Tang dynasty, Shaanxi Province during the Song dynasty (960-1279), Anxi Province during the Yuan dynasty (1271-1368), and Fengyuan Province later in the Yuan dynasty. It functioned as the political, economic and cultural center of northwestern China. In the spring of 1369, the second year of the Ming dynasty, Xu Da, a general under the Hongwu emperor, occupied Fengyuan province and renamed it Xi'an, meaning “to pacify northwest”. Since then, the name of Xi'an has been adopted.


May 20, 1949 celebrated the liberation of Xi'an city. Upon the founding of the People's Republic of China, Xi’an has become a key center for scientific research, higher education, national defense and hi-tech industry in China. It is also a hub of finance, science and technology, education, tourism, and trade in the country's mid-western northern region.
