Karwar, Rajapur, and Mirjan were prosperous ports under his control, and his territory was famous for trade in pepper, silk, betelnut, and saltpeter.
[2][3] Scholar Subah Dayal writes that Randaula Khan and his kin held a monopoly over gun trade around the area of Rajapur.
[4] Randaula Khan played a key role in court politics in the years after Mohammad Adil Shah ascended Bijapur's throne in 1627.
Military pressure from Shah Jahan led to Bijapur deserting its policy of harassing the Mughals around 1635, and Shahji was abandoned in his exploits.
[2] In 1638, Randaula Khan was made commander-in-chief of the Bijapur armies deputed by Mohammad Adil Shah to undertake expeditions in the south.
Subsequently, he turned eastwards on the sultan's orders and advanced on Adoni and Tarpatri - however, he was dissuaded by local ruler Keng Nayak, who convinced him that the town of Bangalore would be a more lucrative target.
After pressuring the ruler with a month-long siege, the latter submitted and offered tribute to Randaula Khan in return for keeping the fort of Mysore.
Randaula Khan pursued the latter, defeated him, arrested him, and shortly after killed him; this encouraged several local nayaks (chieftains) of Karnataka to submit to Bijapur's authority.
