Greco-Bactrian Kingdom
As Mauryan power declined, the Greco-Bactrian Kingdom based in modern Afghanistan declared its independence from the Seleucid Empire, and quickly seized ancient Peshawar around 190 BCE. The city was then ruled by several "Iranic" Parthian kingdoms. The city was then captured by Gondophares, founder of the Indo-Parthian Kingdom. Gondophares established the nearby "Takht-i-Bahi" monastery in 46 CE.
