continued as before, vernacular regional languages based on Sanskrit thrived. A lot of Vedantic literature got translated into these languages between 12th to 15th centuries. Muhammad bin-Qasim and the Chachnama Muslim conquests in the Indian subcontinent began in early 8th century CE with a Muhammad ibn Qasim-led army. This campaign is narrated in the 13th-century surviving manuscript of Chach Nama by Bakr Kūfī, which was claimed to be based on an earlier Arabic record. Content The Chach Nama mentions temple demolitions, mass executions of resisting Sindhi forces and the enslavement of their dependents; kingdoms ruled by Hindu and Buddhist kings were attacked, their wealth plundered, tribute (kharaj) settled and hostages taken, often as slaves to Iraq. According to Wink, a historian specializing in Indo-Islamic period in South Asia, these Hindus were given the choice to either convert to Islam and join the Arab armies, or be sealed (tattooing the hands) and pay Jizya (a tax). The Chach Nama and evidence in other pre-11th century Persian texts suggests that these Hindu Jats also suffered restrictions and discrimination as non-Muslims, as was then usual elsewhere for the non-Muslim subjects (ahl adh-dhimma) per the Islamic law (Sharia), states Wink. Yohanan Friedmann however finds that Chachnama holds most of the contemporary religious as well as political authority to have collaborated with the invaders, and those who promptly surrendered were not only gifted with huge sums of money but also entrusted to rule conquered territories. Friedmann also notes that bin-Qasim "gave his unqualified blessing to the characteristic features of the society"—he reappointed every deposed Brahmin (of Brahmanabad) to their jobs, exempted them from Jizya, allowed holding of traditional festivals, and granted protection to temples but enforced the caste-hierarchy with enhanced vigor, drawing from Sharia, as evident from his treatment of Jats. Overall, Friedmann concludes that the conquest, as described in the Chach Nama, did "not result in any significant changes in the structure of Indian society". According to Johnson and Koyama, quoting Bosworth, there were "certainly massacres in the towns" in the early stages of campaign against pagan Hindus in Sind, but eventually they were granted dhimmi status and peace treaties were made with them. After the conquest of Sindh, Qasim chose the Hanafi school of Islamic law which stated that, when under Muslim rule, people of Indic religions such as Hindus, Buddhists, and Jains are to be regarded as dhimmis (from the Arab term)
