Maratha conquest of North-west India
The Maratha Conquest of North-west India, occurred between 1757 and 1758. Though it was short-lived, it had long-lasting effects upon the politics of the Indian subcontinent.
Background
After the death of Aurangzeb in 1707, the 27 Years War ended in Maratha victory. This was followed by the phase of rapid expansion of the Maratha Empire for the next 50 years under patronage of Shahu and his appointed Peshwa Baji Rao I and Raghoji I Bhonsle. They conquered Gujarat, the whole of Central India and Orissa, subdued Rajputana and raided into Bengal and Tiruchirapalli in Tamil Nadu, and imposed chauth upon these areas. Their ambition pushed them further northwards than Delhi into Haryana, which collided with the ambitions of Ahmad Shah Abdali, the founder of Durrani Empire. In 1757, Ahmad Shah Abdali raided Delhi and captured Punjab and Kashmir with the help of Rohilla chief Najib Khan. He installed his son Timur Shah Durrani in Multan and went back to Afghanistan.The Campaign
The Maratha Peshwa Balaji Baji Rao sent his brother Raghunath Rao along with Shamsher Bahadur, Gangadhar Tatya, Sakharambapu, Naroshankar and Maujiram Bania and a large army towards Delhi. They were accompanied by Malhar Rao Holkar of Malwa who had a long experience of North India and its rulers. The Marathas captured Delhi in August 1757. They decisively defeated the Rohillas and Afghans near Delhi in 1758. The defeat was so decisive that Najib Khan surrendered to the Marathas and became their prisoner.Initial campaign of Sirhind
In Punjab, Adina Beg Khan, along with Sikhs was already in revolt with Ahmad Shah Abdali who had invaded Punjab multiple times and had been repled each time. He decided to call Marathas for help. On 7 March, Raghunathrao had encamped at Rajpura where he received Adina Beg Khan’s envoys, and was informed that the latter, accompanied by 15,000 Sikh fighters, belonging to the bands of Jassa Singh Ahluwalia and Baba Ala Singh of Patiala had closed upon Sirhind from the other side of Satluj. A concerted attack on the fort of Sirhind was made by the Sikhs and Marathas on 8 March 1758. Ahmad Samad Khan, with his 10,000 Afghan troops, held out for about two weeks before his capitulation on 21 March. After the victory, the town was thoroughly sacked by the victors. After defeating the Afghan-Rohilla forces, the Marathas forced the Afghans into the Khyber Pass.Adina Beg's sudden death threw Punjab into turmoil. Many of his soldiers, particularly Afghan mercenaries deserted his army camp and added to the number of freebooters, thus creating chaos and anarchy everywhere. Sikhs started again to revolt against Muslim ruling elite, which had failed to make any permanent settlement with them. Khwaja Mirza who was now the Maratha governor of Punjab could not cope with the situation. He sent an express appeal to the Peshwa for reinforcements, alerted all the junior Maratha officers to help him restoring law and order in the state and recalled Maratha detachments from Peshawar and Attock to safeguard his position in Lahore. Tukoji Holkar and Narsoji Pandit, the Maratha commandants of Attock and Peshawar had to withdraw their troops from the frontier posts. Sabbaji Patil was now given the charge of Peshawar.
Raghunathrao and his deputy Malhar Rao were not interested in holding the position in the north for long. On their request, Peshwa had to find their substitutes. He gave supreme command of Dehli to Dattaji Scindia, while Jankoji Scindia was appointed his deputy. They proceeded towards Delhi separately at different times.
A massive army of Marathas under their new commanders, Scindias reached Machhiwara in March 1759. Like Raghunathrao, Dattaji also didn't want to stay in Punjab for long.
As there was no news of Abdali's invasion, Dattaji deferred the appointment of any permanent governor in Punjab and left it to the Peshwa for decision at his convenience. After deliberations with his advisors, Dattaji deputed Sabbaji to take care of Punjab and Nwfp along with assistance of Bapu Rao, Dadu Rao and Sena Pandit for time being and himself left Punjab for the suppression of Najib-ud-Daula in the Ganga valley. Bapu Rao took the charge of Rohtas Fort, while other officers were appointed on the frontier posts.
Taking advantage of Sabbaji's absence from Peshawar post, the Afghans marched to Peshawar. The Peshawar fort was taken by Afghans with heavy losses to the besieged Maratha garrison. Thereafter the Afghan invaders, under Jahan Khan overran Attock and threatened the Rohtas Fort. By that time, Sabaji Patil reached the place in the Battle of Lahore, with fresh troops and a large number of Sikh fighters, who had once again allied with Marathas. The combined forces of Marathas and Sikhs defeated Afghan garrison in which Jahan lost his son and was himself wounded. The Afghans quickly vacated the forts of Attock and Peshawar and retreated west to Afghanistan. So, Peshawar once again fell to Marathas.
Aftermath
Decline of Maratha power in North-West
It was unbearable for Abdali to overlook this defeat. The Rohilla chief Najib Khan invited Abdali to avenge his defeat. He, along with his commander Jahan Khan invaded Punjab for the fifth time with a massive force of 60,000 accompanied by heavy field-guns. Trimbak Rao's 6000 strong Maratha garrison of Multan was massacred and only 500 of them could cross river Satluj. Lahore, the capital of Punjab, however, did not fall to the Afghans. The remaining Marathas retreated straight to Delhi from their northernmost posts at Sonipat. On 24 December 1759, a battle was fought between Deattaji and Abdali in which Dattaji was defeated with a loss of 2500 Maratha soldiers. As a consequence of victory, Abdali managed to join forces with Najib-ud-Daula.Najib defeated and killed Dattaji at Burari Ghat near Delhi in January, 1760. Abdali followed him. Peshwa Balaji Baji Rao sent his cousin Sadashivrao Bhau to repel Abdali which finally resulted in the Third Battle of Panipat where Abdali decisively defeated Marathas. Panipat debacle was such a blow to the Maratha Empire that it could not enter north India for a decade and could never really recover from the enormous losses they sustained during the whole campaign against the Durrani Empire..After the panipat war Maratha engaged with war with sultan of Mysore Hyder Ali and Tipu Sultan both were defeated. Maratha also engaged with war with Nawab of Hyderabad and defeated Nawab of Hyderabad. Maratha also fought war with East India Company in 1785 and defeated East India Company. There is also crisis in Maratha Leadership after sudden deaths of two succive Peashwas.
Reasons for Decline
The Marathas had failed to befriend the important party of Punjab, particularly Sikhs, even though they had not entered Punjab, they had got close enough to be aided by Sikh troops in numerous battles. They couldn't make any formal treaty with Sikhs, who along with Adina Beg had assisted them in their conquest of north-west. According to an assessment, the Sikhs were ever ready to co-operate with the Marathas, but it goes to the discredit of the Marathas that they could not make a proper confederacy with Sikhs due to their fear of the Sikhs tall statures. Kirpal Singh writes:Finding the Maratha leadership completely off guard against their political foes, many Afghans who were earlier taken captives by Marathas quickly changed their loyalty towards Adina Beg and were recruited in his army. However, later on they betrayed him and joined Abdali's forces during his fifth invasion.
The Peshwa was alarmed by the growing French and British influence in the Deccan. When Abdali invaded Punjab for the fifth time, the Marathas didn't try hard enough to save the frontier posts and instead started planning to save Delhi from another invasion.
The Marathas were considered invaders in Northern India as they came from Central-South India. Moreover, the Marathas were resented by locals because they levied heavy taxes on the locals. The Rajputs detested the Marathas too and wanted to evict them from Northern India, this led to the Rajputs of Jaipur and Marward form an alliance with Ahmad Shah Durrani against the Marathas.
