Pakistani Promotional Model

Modern day Pakistan was at the heart of the Indus Valley Civilisation; that collapsed in the middle of the second millennium BCE and was followed by the Vedic Civilisation, which also extended over much of the Indo-Gangetic plains. Successive ancient empires and kingdoms ruled the region: the Achaemenid Persian empire around 543 BCE, the Greek empire founded by Alexander the Great in 326 BCE and the Mauryan empire founded by Chandragupta Maurya and extended by Ashoka the Great, until 185 BCE. The Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab from 184 BCE, and reached its greatest extent under Menander, establishing the Greco-Buddhist period with advances in trade and culture. The city of Taxila (Takshashila) became a major centre of learning in ancient times — the remains of the city, located to the west of Islamabad, are one of the country's major archaeological sites. The Rai Dynasty (c.489–632) of Sindh, at its zenith, ruled this region and the surrounding territories.
In 712 CE, the Arab general Muhammad bin Qasim conquered Sindh and Multan in southern Punjab. The Pakistan government's official chronology states that "its foundation was laid" as a result of this conquest. This Arab and Islamic victory would set the stage for several successive Muslim empires in South Asia, including the Ghaznavid Empire, the Ghorid Kingdom, the Delhi Sultanate and the Mughal Empire. During this period, Sufi missionaries played a pivotal role in converting a majority of the regional Buddhist and Hindu population to Islam.
