Transitional porcelain is Jingdezhen porcelain, manufactured at China's principle ceramic production area, in the years during and after the transition from Ming to Qing. As with several previous changes of dynasty in China, this was a protracted and painful period of civil war. Though the start date of Qing rule is customarily given as 1644, when the last Ming Emperor hanged himself as the capital fell, the war had really begun in 1618 and Ming resistance continued until 1683. During this period, the Ming system of large-scale manufacturing in the Imperial porcelain factories, with orders and payments coming mainly from the imperial court, finally collapsed, and the officials in charge had to turn themselves from obedient civil servants into businessmen, seeking private customers, including foreign trading companies from Europe, Japanese merchants, and new domestic customers.
