Early Chinese rulers established a unified empire by conquering multiple kingdoms and territories. Under the rule of one emperor, from the 6th to the 4th century BCE to the early 11th century CE, the Chinese civilization experienced a period of economic and cultural prosperity, often referred to as the "Golden Age." It was during this time that significant achievements were made in various fields such as art, literature, philosophy, and science. However, this period of prosperity was interrupted when the Mongols invaded China in the early 13th century CE.
