kalaśa experienced difficulties with his oldest son, harsa, who felt that the allowance granted by his father was insufficient for his extravagant tastes. harsa plotted to kill kalaśa, was found out and eventually imprisoned. his position as heir to the throne was given instead to his younger brother, utkarsa, who was already ruler of lohara. the strain of dealing with harsa caused kalaśa to revert to his previous dissolute lifestyle and stein believes that this contributed to his death in 1089. despite being removed as heir, hasan believes harsa did immediately succeed his father but stein says that utkarsa succeeded and that harsa remained in prison. with the accession of utkarsa to the throne of kashmir came the reunification of that kingdom with lohara, as they had been during the reign of didda. it is at this point that the fortress became the dynastic seat.
