History of Sindh
Sindh was a cradle of civilization as the center of the ancient Indus Valley civilization, and through its long history was the seat of several dynasties that helped shape its identity.
It is believed by most scholars that the earliest trace of human inhabitation in India traces to the Soan Sakaser Valley between the Indus and the Jhelum rivers. This period goes back to the first inter-glacial period in the Second Ice Age, and remnants of stone and flint tools have been found.
Mohenjo Daro
Sindh and surrounding areas contain the ruins of the Indus Valley Civilization. There are remnants of thousand-year-old cities and structures, with a notable example in Sindh being that of Mohenjo Daro. Hundreds of settlements have been found spanning an area of about a hundred miles. These ancient towns and cities had advanced features such as city-planning, brick-built houses, sewage and draining systems, as well as public baths. The people of the Indus Valley also developed a writing system, that has to this day still not been fully deciphered. The people of the Indus Valley had domesticated bovines, sheep, elephants, and camels. The civilization also had knowledge of metallurgy. Gold, silver, copper, tin, and alloys were widely in use. Arts and crafts flourished during this time as well; the use of beads, seals, pottery, and bracelets are evident.
Map of India during the Vedic period, including Sindh
Literary evidence from the Vedic period suggests a transition from early small janas, or tribes, to many janapadas (territorial civilizations) and gana-samgha societies. The gana samgha societies are loosely translated to being oligarchies or republics. These political entities were represented from the Rigveda to the Astadhyayi by Pāṇini. Many Janapadas were mentioned from Vedic texts and are confirmed by Ancient Greek historical sources. Most of the Janapadas that had exerted large territorial influence, or mahajanapadas, had been raised in the Indo-Gangetic Plain with the exception of Gandhara in what is now northern Pakistan’s Khyber Pakhtunkhwa province and eastern Afghanistan. There was a large level of contact between all the janapadas, with descriptions being given of trading caravans, movement of students from universities, and itineraries of princes.
