The Kushan Empire (贵霜帝国) emerged in Central Asia in the first half of the 1st century A.D. After that, its territory expanded rapidly. It controlled most part of Central Asia and the north of India, becoming a strong power on the Silk Road. Under the influence of the Indo Roman maritime trade, the Kushan merchants took an active part in the international trade. They established a huge long distance trade network with three main trade routes which were from the northwest of India to the Western Indian Ocean, Southeast Asia, and the regions east to the Pamirs (帕米尔高原). The Kushan commercial empire continued to exist until the early 4th century A.D., which was an important part of the Silk Road trade in the first few centuries A.D.
