Removing the Sayyid Brothers visits the imperial garden at sunset on a palanquin. On 9 October 1720, Syed Hussain Ali Khan Barha, the commander and chief of the
Mughal army, was assassinated in his encampment in
Todabhim and Muhammad Shah took direct command of the army. Asaf Jah I was then dispatched to gain complete control of six Mughal provinces in the
Deccan, and
Muhammad Amin Khan Turani was assigned as the
Mansabdar of 8000. He was sent to pursue the Mughal Grand vizier Syed Hassan Ali Khan Barha, who was defeated at the battle of
Hasanpur by Muhammad Amin Turani,
Khan-i Dauran, Sher Afkan Panipati, and Amin-ud-Din Sambhali. Hassan Khan Barha fought on the side opposing Khan-i-Dauran where the most danger was anticipated, was captured on 15 November 1720 and executed two years later. The fall of the Sayyid Brothers would mark the beginning of the end of the Mughal Empire's direct control over its dominions in the Deccan.
Loss of Deccan subahs On 21 February 1722, Muhammad Shah appointed Asaf Jah I as Grand Vizier. He advised Muhammad Shah to be "as cautious as
Akbar and as brave as
Aurangzeb". Asaf Jah used his influence with the emperor to fulfil his territorial ambitions in the Deccan. He lost the emperor's confidence when he appointed Hamid Khan, a relative to
Saadullah Khan and his maternal uncle, to administer Gujarat after sending him on the pretext of restoring order to the province. Realising his loss of influence and trust from the emperor, Asaf Jah resigned as Grand Vizier and returned to the Deccan. Asaf Jah I appointed Commander Ewaz Khan as the master of the garrison at
Aurangabad, and much of his logistical duties were carried out by Inayatullah Kashmiri. In 1723 he set out on an expedition to the Deccan, where he fought
Mubariz Khan, the Mughal
Subahdar of the Deccan, who had kept the ravaging
Maratha Empire at bay. Mubariz Khan was a former ally of the Barha Sayyids, who was appointed by Muhammad Shah to kill Asaf Jah I. Taking advantage of Mubariz Khan's conventional weaknesses, Asaf Jah I defeated and eliminated his opponent during the
Battle of Shakar Kheda. Asaf Jah I then established the
Hyderabad State and appointed himself the
Nizam of Hyderabad in 1725. The Mughal-Maratha Wars (1728–1763) would cause irreparable devastation to six Deccan
subahs–
Khandesh,
Bijapur,
Berar,
Aurangabad,
Hyderabad and
Bidar. Asaf Jah would tell the Marathas to invade
Malwa and the northern territories of the Mughal Empire to protect his newfound independence. The Nizam described the
Maratha army to be an instrument to be wielded to his own advantage in the
Maasir-i Nizami: "I consider all this army (Marathas) as my own and I will get my work done through them. It is necessary to take our hands off Malwa. God willing, I will enter into an understanding with them and entrust the
Mulukgiri (raiding) on that side of the
Narmada to them." The ears of Muhammad Shah were possessed by the Amir-ul-Umara, Khan-i Dauran. Muhammad Shah appointed
Qamar-ud-Din Khan as Grand Wazir to succeed Asaf Jah. However, he was quickly dismissed in favour of
Roshan-ud-Daulah Turrah Baz Khan, a native of Panipat, who was appointed the Grand Wazir, in order to reduce the influence of the Turani family. Despite the loss of the Deccan
subahs in 1724, the
Nawab of Awadh Saadat Ali Khan and the Mughal
subahdar Dilawar Khan (r. 1726–1756) remained loyal to the emperor and established a well-protected bastion on the
Malabar Coast.
Cultural developments ", contextually the exalted Urdu Language) written in
Nastaʿlīq script. was built by Muhammad Shah the year 1748. While
Urdu (derived from
Zuban-i Urdū-yi Muʿallá or in local translation
Lashkari Zaban, shortened to
Lashkari) was already in use before Muhammad Shah's reign, it was during his reign that it became more popular among the people and he declared it as the court language, replacing Persian. During Muhammad Shah's reign,
Qawwali was reintroduced into the Mughal imperial court and it quickly spread throughout
South Asia. Muhammad Shah is also known to have introduced religious institutions for education such as
Maktabs ( original arabic plural makātib ). During his reign, the
Quran was translated for the first time into simple
Persian and
Urdu. Also, during his reign, the formal Turkic dress, normally worn by the high Mughal nobility since Mughals originally hailed from
Samarqand, was replaced by the
Sherwani. However, Muhammad Shah's adoption of the Deccan-influenced dress to court would lead to derisive comments, such as "
See how the Deccan monkey dances!" Muhammad Shah was a patron of the performing arts, almost at the cost of administrative priorities, paving the way for the disintegration of governance. While Mughal political power did decline in his reign, the Emperor encouraged the arts, employing master artists such as Nidha Mal (active 1735–75) and Chitarman, whose vivacious paintings depict scenes of court life, such as
Holi celebrations, hunting and hawking. The Mughal court of the time had musicians such as Naimat Khan, also known as
Sadarang, and his nephew Firoz Khan (Adarang), whose compositions popularised the musical form of
khyal. Naimat Khan composed khyal for his disciples and he never performed khyal. This key component of
Indian classical music evolved, ascended and received princely patronage at the court of Muhammad Shah. He himself was a poet under the penname "Sadrang" and was also a composer of
Indian classical raga songs in the
bhairav,
kafi,
dhamar and
malkauns genres. These included songs on the themes of love and the festival of
Holi.
Scientific developments During the reign of Muhammad Shah, a significant scientific work known as the
Zij-i Muhammad Shahi was completed by
Jai Singh II of Amber between the year 1727 and 1735; it consisted of 400 pages.
Rebellious activities against Muhammad Shah In 1719, the Kolis of
Mahi River were most rebellious against Mughal rule and plundering the villages, Mihir Ali Khan, who was acting as Viceroy of Gujarat at the place of
Ajit Singh of Marwar, marched against the Koli rebels of
Mahi who were committing piracy against Muslims and subdued them. In 1721, Kasim Ali Khan, who was an officer of the Mughal Empire under Muhammad Shah employed against the Kolis of Kheda district to collect the fine but they refused to pay and there was a battle in Pethapur between the Kolis and the Mughal Army under Khan. Khan was killed by the Kolis and the Mughal army was defeated and retreated to base. In 1722, Muhammad Bahadur, son of Salabat Khan Babi, was placed in charge of Sadra and Virpur, with the title of Sher Khan. Shortly after his arrival the viceroy marched against and subdued the rebellious Kolis of the Chunval but was wounded deeply. After that Kolis of Modhera opposed Muhammad Shah and Modhera village was burnt down. In 1729, Mughal Viceroy of Sultan Muhammad Shah faced the challenge of anti-muslim activities of Kolis of Sorath, The viceroy marched against Kolis of Sorath and after destroying them, he took them to Ahmednagar. After this, Jawan Mard Khan Babi who was the Governor of Petlad gave an order against rebellious Kolis of Balor, at probably Bhátod about fifteen miles east of Bharuch, but Jawan Marad Khan was killed by a man of the Koli tribe, and in revenge for his death the town of Balor was plundered. On the death of Jawán Mard Khan, at the request of Salabat Muhammad Khan Babi, his eldest son Kamal-ud-din Khan Babi received the districts of Sami and Munjpur and the title of Jawan Mard Khan. In 1738, Sher Khan Babi was in Junagadh appointed as governor of Sorath, Babi was obliged to march against a Koli chieftain Kanji Chunvalia of Chhaniar in Chunval because Kanji opposed and resisted the Mughal authority, but Sher Khan Babi was fiercely resisted by Kolis so Momin Khan was called with a large force and Chhaniar was burned down by the Mughal army. In 1739, Koli chieftain Jamaji of Thara, raised the Kolis of Kankrej against the Padishah and continually plundered Mughal territory. Jawan Mard Khan was ordered to march against the Koli chieftain but he was unable to maintain order, so he requested Fida-ud-din Khan to subdue the Kolis. After defeating the Koli chieftain, the Koli country was plundered by Mughal troops. In 1740, Kolis of Atarsumba, challenged Mughal authority and refused to pay any form of tax to the Mughal Padishah. Jawan Mard khan along with his brother Zorawar Khan Babi, marched against Kolis of Atarsumba but they strongly resisted resulting in a battle, Mughals defeated the Kolis and forced them to pay tax. But it was not for a long time, after some time, Kolis again refused to pay tax and Mughal troops were sent under Abdul Hussain Khan and Vajeram burning three Koli villages. In 1747, Rangoji a Maratha military leader returned to Áhmedábád, and Jawán Mard Khán had an interview with him a few miles from the city. Shortly after this, the Kolis of Mehmudabad and Mahudha rebelled, but the revolt was speedily crushed by Sháhbáz Rohilla.
