Although the name Sultan-Quli might suggest royal dignity, the epithet 'Sultan' is only a part of his name
Qutbu'lmulk never proclaimed his kingship, and in all probability the first ruler of Golkonda to do so was Ibrāhīm Qutb Shāh
Quli Qutb Shah of Golconda was a Turkoman of Qara Qayunlu (Black Sheep) tribe and Yusuf Adil Shah of Bijapur, according to Ferishta, was the son of Sultan Murad II of Turkey.
Vijayanagar king Krishnadevaraya opted to march against the Qutb Shah leader. He came with 30,000 horses and 3,000 foot soldiers. Quli Qutb responded, and the two armies met at Pangal where the Vijayanagar army had encamped. In battle, the Golconda forces were successful, forcing the retreat of Krishnadevaraya who left behind a small force to defend the fort. The fort occupants held out for nearly two months before capitulating to the besieging Qutb Shah forces.
