Although Darvesh Padshah was Ibrahim's eldest son, Mohammed Adil Shah was raised to the throne in 1627 on his father's death, at the age of fifteen. Mohammed Adil Shah of Bijapur partnered with the
Mughals in their conquest of
Ahmednagar. Mohammed maintained friendly relations with
Shah Jahan and made a peace treaty of 1636, after the extinction of
Ahmednagar. By a
firman of
Shah Jahan, he got assurances for the end of Mughal aggression against
Bijapur and due to his good relations with the Mughals,
Shah Jahan formally recognized Muhammad's sovereignty and bestowed upon him the title of
Shah in 1648, the only ruler of Bijapur to receive such recognition from the Mughals. The Treaty of 1636 with the
Mughals sealed the expansion of Bijapur in the north. So, Mohammed Adil Shah extended his dominations westwards into
Konkan,
Pune, Dhabul (present
Mumbai), southwards into
Mysore, and eastwards into
Karnataka, present south
Andhra Pradesh and
Tamil Nadu. During his reign, the kingdom attained its greatest extent, power and magnificence, and his dominions stretched from the
Arabian Sea to the
Bay of Bengal. Besides territorial expansions, Bijapur also attained peace and prosperity during Mohammed's reign. His kingdom yielded an annual revenue of seven crore eighty four lakh rupees, besides the five and half crores of tributes that were from vassal rulers and
zamindars. Cultural activities like poetry, painting and architecture also received a great impetus. Mohammed Adil Shah did his best to emulate the glorious traditions left to him by his versatile
father. Diffusion of general education and religious teachings were one of his chief concerns, and he did his utmost to improve the socio-economic and educational standards of the people. Mohammed continued his father's patronage of the arts, though on a lesser scale. He introduced
fresco paintings and portraits, the examples of which are the walls of
Asar Mahal, pavilion at Kumatgi and
Sat Manzil. ==The Marathas' insurgency==
