 A Mughal province , which comprised the Carnatic region south of the Tungabhadra river , and which was to exist for seventy years , was established in 1687 with its capital at Sira ( in Tumkur District ) . ( See Map 10 . ) Known as the Province of Sira ( also Carnatic @-@ <unk> ) , it was composed of seven <unk> ( districts ) : <unk> , <unk> , Sira , Penukonda , Dod @-@ Ballapur , Hoskote , and Kolar ; in addition , <unk> , <unk> , <unk> , Bednur , Chitaldroog , and Mysore were considered by the Mughals to be tributary states of the province . Qasim Khan ( also , <unk> Khan or Kasim Khan ) was appointed the first Subahdar ( governor ) and Faujdar ( military governor ) of the province in 1689 . Having displayed " energy and success " both in controlling and in developing the province , he died in 1694 , either killed by Maratha raiders from the northwest , or killing himself in disgrace after these raiders seized a treasure under his care . Most <unk> who governed after him were to be replaced in a year or two by a successor . The instability would continue until Dilavar Khan was appointed governor in 1726 , his term lasting until 1756 . In 1757 , Sira was overrun by the Marathas , only to be restored to the Mughals in 1759 . In 1761 future ruler Haidar Ali , whose own father had been the Mughal military governor ( or Faujdar ) of Kolar district in the province , captured Sira , and soon conferred on himself the title of " Nawab of Sira " . However , the defection of his brother five years later caused the province to be lost again to the Marathas , who retained it until Haidar 's son , Tipu Sultan , recaptured it for his father in 1774 .
