context_page_description: The Tang dynasty or the Tang Empire was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period in Chinese history. Historians generally regard the Tang as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty. The Tang capital at Chang'an was the most populous city in the world in its day.
  The Lǐ family founded the dynasty, seizing power during the decline and collapse of the Sui Empire. The dynasty was interrupted for 15 years when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. In two censuses of the 7th and 8th centuries, the Tang records estimated the population by number of registered households at about 50 million people.
context_section_description: Through use of the land trade along the Silk Road and maritime trade by sail at sea, the Tang were able to acquire and gain many new technologies, cultural practices, rare luxury, and contemporary items. From Europe, the Middle East, Central and South Asia, the Tang dynasty were able to acquire new ideas in fashion, new types of ceramics, and improved silver-smithing techniques. The Tang Chinese also gradually adopted the foreign concept of stools and chairs as seating, whereas the Chinese beforehand always sat on mats placed on the floor. In the Middle East, the Islamic world coveted and purchased in bulk Chinese goods such as silks, lacquerwares, and porcelain wares. Songs, dances, and musical instruments from foreign regions became popular in China during the Tang dynasty. These musical instruments included oboes, flutes, and small lacquered drums from Kucha in the Tarim Basin, and percussion instruments from India such as cymbals. At the court there were nine musical ensembles (expanded from seven in the Sui dynasty) representing music from throughout Asia.
  There was great contact and interest in India as a hub for Buddhist knowledge, with famous travelers such as Xuanzang (d. 664) visiting the South Asian state. After a 17-year-long trip, Xuanzang managed to bring back valuable Sanskrit texts to be translated into Chinese. There was also a Turkic–Chinese dictionary available for serious scholars and students, while Turkic folksongs gave inspiration to some Chinese poetry. In the interior of China, trade was facilitated by the Grand Canal and the Tang government's rationalization of the greater canal system that reduced costs of transporting grain and other commodities. The state also managed roughly 32,100 km (19,900 mi) of postal service routes by horse or boat.
