The ancient region of northeastern Afghanistan and northwestern Pakistan was situated at a confluence of trading paths along the Silk Route, an area was flooded in cultural influences ranging from Greece to China. After the conquests of Alexander the Great, the creation of Greco-Bactrian kingdoms, and the general Hellenization of the subcontinent, Western aesthetical tastes became prominent. Greek influence began to permeate into the arts and culture. Eventually, the Bactrian Kingdom was absorbed by the nomadic Kushan tribes, who settled in the region and went on to establish their own dynasty. The area flourished under the Kushan and their greatest king, Kanishka, who traditionally given credit for further spreading the philosophies of Buddhism throughout central Asia and into China. This period is viewed as one of the most important era in the history of Buddhism.
