Sultanate of Bijapur
The Sultanate of Bijapur was an early modern kingdom in the western Deccan and South India, ruled by the Muslim Adil Shahi dynasty. Bijapur had been a taraf of the Bahmani Kingdom prior to its independence in 1490 and before the kingdom's political decline in the last quarter of the 15th century. It was one of the Deccan sultanates, the collective name of the kingdom's five successor states. The Sultanate of Bijapur was one of the most powerful states on the Indian Subcontinent at its peak, second to the Mughal Empire which conquered it in 1686 under Aurangzeb.
After emigrating to the Bahmani Sultanate, Yusuf Adil Shah rose through the ranks to be appointed governor of the province of Bijapur. In 1490, he created a de facto independent Bijapur state which became formally independent with the Bahmani collapse in 1518.
The Bijapur Sultanate's borders changed considerably throughout its history. Its northern boundary remained relatively stable, straddling contemporary southern Maharashtra and northern Karnataka. The sultanate expanded southward, its first major conquest the Raichur Doab after defeating the Vijayanagara Empire at the Battle of Talikota in 1565. Later campaigns in the Karnatak and Carnatic extended Bijapur's borders and nominal authority as far south as Tanjore. For most of its history, Bijapur was bounded on the west by the Portuguese state of Goa, on the east by the Sultanate of Golconda, on the north by the Ahmednagar Sultanate and on the south by the Vijayanagara Empire and its succeeding Nayaka dynasties.
The sultanate clashed incessantly with its neighbours. After the allied victory against Vijayanagara at Talikota in 1565, the state expanded through its conquest of the neighbouring Bidar Sultanate in 1619. The sultanate was then relatively stable, although it was damaged by the revolt of Shivaji. From the late 16th century, the greatest threat to Bijapur's security was the expansion of the Mughal Empire into the Deccan. Agreements and treaties imposed Mughal suzerainty on the Adil Shahs, by stages, until Bijapur's formal recognition of Mughal authority in 1636. The influence of their Mughal overlords and continual strife with the Marathas sapped the state of prosperity until the Mughal conquest of Bijapur in 1686.
The former Bahmani provincial capital of Bijapur remained the sultanate's capital throughout its existence. After modest earlier developments, Ibrahim Adil Shah I and Ali Adil Shah I remodelled Bijapur with a citadel, city walls, and a congregational mosque. Their successors, Ibrahim Adil Shah II, Mohammed Adil Shah and Ali Adil Shah II, added palaces, mosques, a mausoleum and other structures to the capital.
History
The founder of the dynasty, Yusuf Adil Shah, may have been a Georgian slave who was purchased by Mahmud Gawan. Other historians have said that he is of Persian or Turkmen origin. According to the contemporary historian Firishta, Yusuf was a son of the Ottoman Sultan Murad II; however, this is disputed by modern historians. Another theory is that he was an Aq Qoyunlu Turkman.Founding and consolidation (1490–1580)
Yusuf impressed Bahmani Sultan Muhammad Shah III, and he was appointed governor of Bijapur. Yusuf took advantage of Bahmani decline to establish himself as an independent sultan at Bijapur in 1490, pursuing the same goal Malik Ahmad Nizam Shah I had that year. He proclaimed Shia Islam as the official religion of his territorial holdings in 1503, following the lead of Shah Ismail of the Safavid dynasty. Yusuf conquered and annexed the Bahmani taraf of Gulbarga the following year and reinstated his Shia mandate shortly afterwards, a year after he revoked it under threat of invasion. A Portuguese Empire colonial expedition led by Afonso de Albuquerque exerted pressure on the major Adil Shahi port of Goa, conquering it in 1510; Yusuf retook the settlement two months later, but the Portuguese again conquered it in November of that year.Yusuf died in 1510, between these two clashes with the Portuguese, when his son Ismail Adil Shah was a boy. Ismail's regent, Kamal Khan, staged an unsuccessful coup against him; he was killed, and Ismail became the absolute ruler of Bijapur. In 1514, a dispute over Gulbaraga province led the rulers of the Ahmednagar, Golconda, and Bidar Sultanates to unsuccessfully invade Ismail Adil Shah's provinces. Krishnadevaraya, ruler of Vijayanagara, laid siege to the Bijapuri fort of Raichur in 1520. The siege continued for three months until the emperor's encounter with Ismail, who attempted to end it. Ismail was defeated by Krishnadevaraya in the Battle of Raichur; initially successful, with an advantage in artillery, Ismail was routed by the Vijayanagara forces in a surprise counter-attack which scattered much of his forces. Soon after Ismail's retreat, Krishnadevaraya captured the Raichur fort. In a later diplomatic conflict, Krishnadevaraya occupied Bijapur for an extended period and the sultan refused to see him. Ismail invaded the territory of Amir Barid I of Bidar in 1529, besieging his capital; Aladdin Imad Shah of Berar unsuccessfully tried to mediate the conflict. Amir Barid surrendered the fort of Bidar, which was looted by Ismail and his troops. Ismail recaptured Raichur and Mudgal from Vijayanagara the following year, after the death of Krishnadevaraya. Amir Barid agreed with Ismail to cede him the forts of Kalyani and Qandhar in exchange for Ismail's surrender of Bidar.
Ismail was succeeded in 1534 by Mallu Adil Shah, whose reign was short-lived. Installed by a prominent Bijapuri noble, Asad Khan, he is noted for incompetence; Vijayanagara invaded the sultanate and seize the Raichur Doab from the Adil Shahis. Mallu Adil Shah was soon blinded and removed from power.
Ibrahim Adil Shah I, Ismail's son, succeeded Mallu the following year. He established Sunni Islam as the state religion and made anti-Westerner changes, abolishing the use of Persian in some administrative tasks and replacing many Westerners with Deccanis. Ibrahim also invaded the Vijayanagara Empire; he pillaged a number of cities and besieged the capital, Vijayanagara, but did not seize any territory in the long term and returned home with only non-territorial rewards. In another conflict with the Portuguese, Ibrahim ceded two ports in the fear that trade through Goa might be cut off from the Adil Shahis. His kingdom was invaded four times by Ahmednagar Sultanate forces, the sultanate's greatest adversary. Sultan Burhan Nizam Shah I initially allied himself with Bidar in his first invasion but Bidar, ruled by Ali Barid Shah I, allied itself with Bijapur in the second invasion: a quadruple alliance of Ahmednagar, Jamsheed Quli Qutb Shah of Golconda, Vijayanagara, and Darya Imad Shah of Berar. The war was a defeat for the Bijapuri–Bidar side, who ceded a northern district of the Bijapur Sultanate to Ahmednagar. Burhan and Ibrahim allowed Ahmednagar freedom to expand in Bidar if Bijapur had the same freedom to annex lands from Vijayanagara; Ibrahim imprisoned Ali Barid Shahi of Bidar despite their former alliance, although he was later freed by Jamsheed. Burhan Nizam Shah besieged the Bijapuri city of Solapur four times, but did not retain it until a third invasion which occupied territory on the southern border. Burhan advanced in a fourth invasion in 1553 with Vijayanagara almost to the Bijapuri capital, but retreated due to failing health.

Ali Adil Shah I, who ascended the throne in 1558, reestablished Shia Islam as the state religion. He unsuccessfully asked Hussain Nizam Shah I for the return of Solapur and Kaliyani and then invaded the Nizam Shahi kingdom with assistance from Vijayanagara's de facto ruler Rama Raya and Ibrahim Qutb Shah, besieging Ahmednagar and other cities. Hussain sued for peace in 1561, submitting to Rama Raya and returning Kaliyani to Ali Adil Shah. In 1563, Hussain attempted to regain Kaliyani and again besieged it. Ahmednagar was besieged by Ali, and Hussain was forced to abandon his siege of Kaliyani; the only beneficiary of the conflict was Vijayanagara, who gained territory from invading Golconda. Vijayanagara negotiated additional land from Bijapur, including the cities of Yadgir and Bagalkote. Wary of Vijayanagara's growing power, Ali allied his forces with the sultans of Golconda, Ahmednagar and Bidar and defeated the Vijayanagara Empire in the 1565 Battle of Talikota. Rama Raya was beheaded after his capture by Deccani forces. Vijayanagara and nearby cities were sacked and looted, and historian Hermann Goetz said that this prompted the emigration of much of Vijayanagara's population to Bijapur. The Raichur Doab and its surrounding area were returned to Bijapur. The Vijayanagara military was demolished, and the kingdom was a shell of its former self. Ali I then fortified Bijapur with a wall, which facilitated the further centralization of authority. Subsequent architectural projects encouraged the growth of the city and its skilled class. Another conflict between Ahmednagar and Bijapur arose in 1567; although Ali invaded Ahmednagar and his forces occupied a number of forts, the war ended in a stalemate. A 1570 conflict with the Portuguese began with the hope of expelling them from India, but Ali was defeated after a number of encounters the following year. He then annexed more land from Vijayanagara in a campaign which lasted until 1575, conquering Adoni and much of the Carnatic. Ali also began a campaign to capture the Karnatak; according to Richard M. Eaton, his "armies destroyed two to three hundred Hindu temples" which were replaced with Shia buildings. By 1576, land gained under Ali I had doubled the sultanate's holdings. He forged diplomatic relations with the Mughals, Ottomans, and Safavids during his reign, which Eaton says brought the sultanate into the dar al-islam.
