The rulers before Islam were: Siharus, Sahasi II, Chach, Dahir. The first two were Buddhist Jatt, and the last two were Hindu jatt. The new Brahmin rulers were not friendly to the many Buddhists in Sind at that time, and they were cruel to the Jats and Meds, who were most of the peasants. Bad conditions were put on the Jats and they lost many civil rights. "When Chach, the Brahmin chamberlain who usurped the throne of Chach King went to Brahmanabad, he enjoined upon the Jats and Lohanas not to carry swords, avoid velvet or silken cloth, ride horses without saddles and walk about bare-headed and bare-footed". It was because of this background that Muhammad bin Qasim received cooperation from the Buddhists as well as the Jats and Meds during his campaign in Sind ("An advanced history of India" by Ramesh Chandra Majumdar; Hemchandra Raychaudhuri; Kalikinkar Datta Delhi: Macmillan India, 1973).
