"

Balochistan occupies the very southeasternmost portion of the Iranian plateau, the setting for the earliest known farming settlements in the pre-Indus Valley civilisation era, the earliest of which was Mehrgarh, dated at 7000 BCE,[1] within the province. Balochistan marked the westernmost extent of civilisation. Centuries before the arrival of Islam in the seventh century, parts of Balochistan were ruled by the Paratarajas, an Indo-Scythian dynasty. At certain times, the Kushans also held political sway in parts of Balochistan.[citation needed]
