 Around this time a change had come in the governance of the Mughal Province of Sira to the north and northeast of Mysore . ( See Map 11 . ) In 1713 , the province was split into a <unk> jurisdiction with capital at Arcot and governed by a newly styled Nawab of Arcot , and a <unk> jurisdiction with capital at Sira , and governed by an also newly styled Nawab of Sira . That same year , the military governor of the old province , Sadat @-@ <unk> Khan , was made the new Nawab of Arcot , and another official , Amin Khan , was appointed Nawab of Sira ; Since Mysore remained a formal tributary state of Sira , this division , and the resulting loss of revenue from the rich <unk> plain of Mysore , provoked Sadat @-@ <unk> Khan 's displeasure . In collusion with the rulers of Kadapa , Kurnool , and <unk> and the Maratha Raja of <unk> , he decided to march against Dodda Krishnaraja I. The Nawab of Sira , anxious to preempt the coalition 's action , hit upon a similar plan for reaching the Mysore capital , Seringapatam . In the end , both Nawabs — of Arcot and Sira — settled upon a joint invasion led by the former . Dodda Krishnaraja , for his part , was able to " buy off this formidable confederacy " by offering a tribute of Rs . 10 million ( 10 million ) . Although avoiding bloodshed , the outcome made Mysore vulnerable to similar future claims , which were made successfully two years later by Maratha raiders who appeared in the Mysore capital . The resulting depletion of the Mysore treasury led Mysore to attack and absorb the poligar chiefdom of <unk> to its north . ( See Map 11 . )
