Wanaparthy Samsthanam or Raja of Wanaparthy was a vassal of Nizam of Hyderabad. The tradition had a place with Brahmin clan. He controlled the feudatory of Wanaparthy. It was one of the three critical examples, the other two being Gadwal and Jatprole. Wanaparthy Samsthanam follows its history back to fourteenth century after the Kakatiya kingdom declined. The progressive Turkic Muslim lines, who attacked and settled in Deccan, thought that it was perfect for Samsthanam to win. It was encompassed by three other Samsthanam.
The early Rajas kept up an armed force numbering 2000 infantry and 2000 rangers. The time the kingdom fell into the ambit of the ground-breaking Hyderabad State, until the point when Wanaparthy's military were assimilated into the Hyderabad Army as the Bison unit on the requests of Nizam of Hyderabad. The ruler was consigned from officer to the privileged post of Inspector of the Bison brigade. Ensuing to the Hyderabad State's merger with the Indian Union in 1948, all units of the Hyderabad State Forces were disbanded and volunteers ingested into the Indian Army.
