 The early 18th century ushered in the rule of Kanthirava Narasaraja II , who , being both deaf and mute , ruled under the regency of a series of army chiefs ( Delavoys ) all of whom hailed from a single family from the village of Kalale in the Nanjangud taluk ( or sub @-@ district ) of Mysore . Upon the ruler 's death in 1714 at the age of 41 , his son , Dodda Krishnaraja I , still two weeks shy of his 12th birthday , succeeded him .
