[1] After 1857, Indore became a 19-gun salute princely state within the Central India Agency of the Indian Empire under British protection.
In 1733, the Peshwa assumed full control of Malwa and appointed his commander Malhar Rao Holkar as the subahdar of the province.
His daughter-in-law Ahilyabai Holkar moved the state's capital to Maheshwar in 1767, but Indore remained an important commercial and military centre.
The Holkar dynasty was able to continue to rule Indore as a princely state mainly owing to the efforts of Dewan Tatya Jog.
In 1926, Maharaja Tukoji Rao III Holkar XIII abdicated after being implicated in a murder case involving a court dancer and her lover.
Yashwant Rao Holkar II, the last ruler of the state, signed the instrument of accession to the Indian Union on 1 January 1950.
