Sindh is Pakistan's southernmost mainland province, a 141,000 sq km triangle bounded by the Arabian Sea, the Thar Desert to the east, the Kirthar range to the west, and Punjab and Balochistan to the north. It is the ancient heartland of the Indus Valley Civilisation, with Mohen-jo-Daro (built around 2500 BCE) as its most famous ruin, and one of the earliest points where Islam entered the subcontinent (Muhammad bin Qasim landed at Debal in 711 CE). Karachi, the province's capital and Pakistan's largest city, sits at the mouth of the Indus and is the country's principal port. Local people speak Sindhi (an Indo-Aryan language with an unbroken literary tradition going back to the 8th century), Urdu (dominant in Karachi), and Balochi in the western belt.
