We were  taught that Muslims ruled our country for nearly a thousand years and  the British took over thereafter. Did you know that the Marathas  ruled over most of India during the 18th  century. This article tells you about the Peshwas, how Marathas won  wars in other parts of India (to substantiate the title), Nana Saheb,  Scindias, Holkars, and lastly causes of the downfall of the Maratha  empire. Short forms used are Maratha is Mts, Mughals is M, Shivaji is  S, Aurangzeb is A, P is Peshwa. 
This article is based on Volume  VIII – The Maratha Supremacy” of the magnum opus – “The  History and Culture of the Indian People”, General  Editor R.C. Majumdar, published by Bharatiya Vidya Bhavan, Second  Edition, 1991.
This article was first written in  March 2008 and edited in March 2017. 
1800-1820 
Peshwas: The 18th  century is rightly looked at, as the age of Maratha supremacy. While  people revolted after Aurangzeb’s death, the Marathas, on account  of their simple habits, hardihood and, national fervor proved to be  the most successful. Shahu’s Raja Peshwa Balaji Vishwanath  understood the changed situation and decided to get actively involved  in other parts of India. Under his son and grandson, Marathas  succeeded in conquering Malwa (area around modern day Indore),  Gujarat, and Bundelkhand part (in U.P.) and levied tribute from  Bengal to Punjab and from Agra to Arcot (in Tamil Nadu).  Unfortunately, they did not develop satisfactory administrative and  cultural institutions to win the loyalty of the people. 
After the setback of Panipat in  1761, Mahaji Sindia became the kingmaker of Delhi and remained in  charge till 1794. Thus, the British  had to fight the Marathas and  not the Mughals. Between 1800 and 1818, the British smartly divided  the Maratha chieftains and defeated them thereafter. 
After  escaping from the clutches of the Mughals in 1707, Shahu established  contact with several Maratha chieftains like Peshwa Bhonsle of Berar.  Unwilling to accept Shahu as the king, Tarabai fought and lost a  battle with Shahu in 1707. This opened the doors of Swaraj to Shahu  i.e., the areas of Satara and Poona. 
A mention  must be made of Kanhoji Angria, a brave and daring person whose ships scoured the Western coast and  made him immensely rich and powerful. His name evoked fear in the  minds of the Siddis, British, Dutch, and Portuguese. Balaji Peshwa  convinced Angria on the futility of a fight and got him to side with  Shahu and not Tarabai. 
At end of  article read about Kanhoji A - India's first  naval commander. Excerpts, "The first  important naval figure in modern India, Angre managed to maintain an  unquestionable hold over a heavily disputed stretch of coastline  throughout the early decades of the 18th  century. At its peak in 1729, Angre’s Maratha fleet held a mere 80  ships, many of them little more than overgrown fishing boats  engineered by the local kolis (fisher folk) who populated his domain. Yet with the combination of  that modest fleet and an unsurpassed strategic mind, Angre  established a fearsome authority in the name of the Maratha Emperors  over a vast swath of India’s west coast. The competition was fierce  and came from some of the greatest powers of the day – the  Portuguese, the British, and the Mughals in the form of their coastal  vassals, the Siddis."
Eager to curb the  growing power of the Marathas, the Mughal king appointed  Nizam-ul-Mulk as the governor of Deccan. Advocating a strong policy  towards the Marathas in the Deccan, he took them on, winning some and  loosing others. Unable to control them, the Nizam came to an  understanding with the Peshwa. 
A few  months later he got transferred and was replaced by Husain Ali. He  too, advocated a strong policy against the Marathas initially, but  later on came to a formal agreement by which the Marathas could levy  chauth on the six provinces of the Deccan (Aurangabad, Berar,  Khandesh, Bidar, Golconda, and Bijapur which included the whole of  Karnataka), Malwa, and Gujarat, the old conquests of Shivaji to be  restored and Shahu’s family to be set free. 
In return  for all this, the Marathas would maintain 15,000 troops to aid the  emperor and pay an agreed annual fee. Realizing that this meant  virtually abdicating his control over the Deccan, the emperor refused  to ratify the treaty and prepared for war, and called to his aid S  Khan from Patna, Nizam-ul-Mulk from Moradabad and Ajit Singh from  Gujarat. 
However,  Husain Ali and the Marathas entered Delhi in February 1919, forced  the Mughal ruler to sign the treaty. Balaji Vishwanath who had  accompanied Husain Ali to Delhi returned to the Deccan in May 1919,  with the deeds and Raja Shahu's family.  The treaty marked a triumph  of Raja Shahu. His recognition by the Mughal authority gave him an  advantage over Shambhuji and made other Maratha chieftains look up to  him as a man of authority. Mughal rulers recognized the supremacy of  the Marathas in the south by granting them the right to collect  revenue from six provinces in Deccan. 
Subsequently,  jagirs were doled out  to various Maratha chiefs like the Bhonsles, Angria etc. The chiefs  could do what they wanted in their areas by adhering to central  directives mainly in the area of defence. As a consequence, this  concentrated too much power in the hands of these chiefs without  providing adequate checks. Balaji attempted to create a federal  structure unlike Shivaji, who favored a central monarchy. Creation of  these jagirs expanded the Maratha Empire but was responsible for its  downfall too. 
Historians  point out that this “granting of authority over territory instead  of salaries” to the officers by Balaji Vishwanath was a departure  from the wise rule of Shivaji but throw the blame on the master and  not on the minister. 
Balaji  passed away in 1720, leaving his son Bajirao Peshwa to succeed him.  Hereafter, the house of Shivaji faded away gradually, with the  Peshwas ruling the roost. Balaji Vishwanath Bhat has been truly  called 'the second founder of the Maratha state'.
Baji  Rao Peshwa 
He became Peshwa at the age of 20. There was criticism against appointing a  person so young but Raja Shahu was committed to the appointment. By  the circumstances of his upbringing and inclination, Raja Shahu   lacked the will to assert himself and be bothered about the details  of administration. It resulted in a gradual transfer of powers to the  Peshwa hand from those of the Chhatrapati.

The Turani  party which subsequently came to power in Delhi, refused to follow  the treaty signed by the emperor in March 1719. The Deccan was seized  by the Nizam who in collusion with Raja Shahu's rival, Shambhuji of  Kolhapur threatened to destroy the Maratha State. 
The Nizam,  Mir Qamar-ud-din, used the Marathas to overcome his Mughal rivals but  refused to cooperate with the Marathas in recovering chauth from  Karnatak. The Nizam  wanted to break  away from the Maratha’s shackles so he shifted  capital from Aurangabad to Hyderabad. 
Eventually  the Nizam was overcome in 1728 in the Battle of Palkhed. Peshwa  marched towards Aurangabad but avoided taking the enemy headon.  Instead he moved towards Gujarat with Nizam’s army in hot pursuit.  The pursuit was abandoned in the hilly tract and Nizam occupied Pune  instead. Peshwa now attacked Nizam’s capital Aurangabad, and was  challenged for action in a waterless tract near Palkhed. Starved of  food and water, Nizam sent a word to Peshwa, asking for peace. Field  Marshal Montgomery, who held a leading part in the defeat of Hitler,  has in his book, A History of Warfare, listed some of the all time important battles, and selected the  Battle of Palkhed as one that was brilliant in strategy and fought in  the style of Mughals. 
At end of  article read The Maratha Military Genius: The Battle of  Palkhed. Excerpts "Baji Rao resisted  “urgent calls” to rush back to defend Poona. Instead, the Nizam,  while at Baramati, learned to his horror, that the “Peshwa had  burst eastward through the Kasarbari Pass and was marching towards  Aurangabad, the heart of the [Nizam’s] kingdom.”
The Nizam started in pursuit, but found  his army cut off from all supplies to water near Palkhed on 25  February 1728. “Starved of food and water”, the Nizam’s army  would not fight, though his heavy artillery was able to keep the  Peshwa’s army at arm’s length.
Through the intercession of Iwaz Khan,  the “Nizam sent the Peshwa a word of his miserable plight and his  willingness to come to terms.” The Nizam’s army was only then  allowed to move near the river. A treaty – generous to the Marathas  – was entered into between the Peshwa and the Nizam at  Mungi-Paithan on 6 March 1728. The Nizam agreed to every single term  set by the Marathas, save one – the handover of Sambhaji (of  Kolhapur).
A famous battle was thus concluded  where there was no mass slaughter of soldiers on either side – that  would take place 34 years later on the plains of Panipat, where  arguably the largest number of deaths in a single day on a  battlefield in history would be recorded.
This battle is remembered for it being  a “masterpiece of strategic mobility”. It is useful to read what  Field Marshall Montgomery had to write about this battle in his book:
Baji Rao’s army was a purely mounted  force, armed only with sabre, lance and a bow in some units, and a  round shield. There was a spare horse for every two men. The Marathas  moved unencumbered by artillery, baggage, or even handguns and  defensive armour. The lightly equipped Marathas moved with great  rapidity, avoiding the main towns and fortresses, living off the  country, burning and plundering. … The Nizam for a time pursued  them but was bewildered by the swift and unpredictable movements of  the enemy, and his men became exhausted."
The  growing ambition of Bajirao, coupled with the independent streak of  various chieftains, was bound to result in conflict, the area being  Gujarat. Elated by his victories, Peshwa was in no mood to give up  the claims on Northern Gujarat; others like Gaikwars, Bhonsle, and  Pawars were opposed to the Peshwa’s designs. At this stage, young  Dabhade (chieftain) made a tactical blunder of holding secret  negotiations with Nizam to seek his help. Getting a whiff of this,  Peshwa invaded Gujarat and defeated the combined forces of the  Senapati - Nizam. This victory was a landmark in the history of  Peshwas as it left them without a rival at home. 
Bajirao  also undertook a campaign against the Sidis of Janjira in 1733. Under  pressure, the Sidi chief sought and obtained support from the  English. According to the terms of settlement the Peshwa agreed not  to claim beyond what territory was then in actual possession of the  invading force. The Sidi was driven back to the sea, his territory  dwindled. The Marathas became masters of much of his land possession.  But Sidi Saat was overcome in 1736 when his small force was defeated  by Peshwa's brother Chimnaji Appa near Rewa in 1736. The Sidi's power  declined and the Sidi became in all but name, a tributary of the  Marathas. 
Realizing  the weakness of the Mughal Empire, Peshwa pursued his northward  expansion drive with zeal. He brought Malwa, Gujarat and, Bundelkhand  (parts of Western, central U.P.) under Maratha control, thereby, for  the first time in the history of Bharat making Deccan as the point of  controlling Hindustan. (means Urdu speaking areas of the Indian  sub-continent). 
A mention  must be made (subject of movie Bajirao Mastani) of Baji Rao's war in  Bundelkhand, at behest of Raja Chhatrasal, when he was hard pressed  by Muhammad Khan Bangash, governnor of Allahabad. Baji Rao defeated  Khan. In lieu the Marathas were paid a grant of Rs 5 Lakhs. Marathas  got another foothold from which to mount their offensive against the  Mughal Empire. 
In October  1730, Malhar Rao Holkar and Ranoji Sindia were granted the jagir of  Malwa with them making Indore and Ujjain their headquarters. Peshwa’s  march to Delhi started  with his arrival in northern Bundelkhand just about 70 kms of Agra.  Malhar Rao Holkar lost to the Governor of Avadh, S. Khan forcing  Peshwa to make a tactical retreat. 
While the  Mughals were celebrating their victory, (It is rightly said, “Never  celebrate till your enemy is vanquished, even if you do, keep your  forces on alert.), Peshwa took a detour through modern day Haryana  and descended to Delhi. On reaching Delhi, he changed his mind and  decided not to attack. Because of some misunderstanding, Mughals  attacked  Peshwa’s forces only to be routed. The successful march  had led to a surge in the Peshwa’s reputation and generated awe in  the enemy’s camps. 
Unable to  accept the growing might of Peshwa, Mughals invited Nizam and other  Rajput chiefs to join hands and push the Peshwa to south of the  Narmada. Through a series of strategic moves, Peshwa cut off supply  lines to various parts of this alliance, defeated them and forced  Nizam to beg for signing a treaty in 1738. Called the victory of  Bhopal, it marks the zenith of Peshwa’s career. It also implied the arrival of a new power in  Hindustan. 
Nizam  failed to keep his promise of ratifying the terms of the treaty.  Serious doubts assailed Peshwa’s mind that allowed Nizam to escape  in 1728 (Palkhed) and 1738 (Bhopal). If Peshwa had not done so, may  be, Bharat might not have faced the problems with Nizam’s state,  Hyderabad, at the time of partition. This has been one of the  weaknesses of Indian rulers, a refusal to crush the enemy once and  for all. Prithviraj Chauhan made the mistake with Mahmud Ghazni, only  to be killed later, Nehru made it in Kashmir in 1948, Indira Gandhi  repeated the mistake in 1972. 
While  Bajirao was overrunning Hindustan, his brother Chimnaji Appa defeated  the Portuguese in 1740, ending their rule in North Konkan. The  persecution of all those who did not conform to the Christian  doctrine forced the Hindu leaders to secretly invite the Peshwas to  free them of foreign rule. The conquest of Bassein was long cherished  by the Marathas as a matter of national pride and glory.
Summary  of Bajirao’s reign
The last  few years of the Bajirao’s life were clouded by domestic discord.  He was fond of a mistress and drank, ate meat in her company. He  passed away in 1740. In the words of Sir Richard Temple, “He died  as he lived, in camp under canvas among his men and he is remembered  to this day among the Marathas, as the fighting Peshwa and the  incarnation of Hindu energy.” 
Besides  securing the Deccan, he was the first Maratha to go on the offensive  streak in Hindustan. Leading his armies beyond the Narmada, he over  ran the Mughal provinces of Gujarat, Malwa and Bundelkhand. It was  his policy of northward drive that brought the provinces of Punjab to  Bengal under Maratha influence by 1760. 
If Shivaji  created a Maratha state, Bajirao transformed it into an empire. While  he extracted revenue ably, he paid no heed to the problems of  governance. He was a matchless cavalry leader but not statesmen or a  far sighted reformer. The Jagir system vested more money in the hands  of satraps like Holkars, causing a debt of INR 14 lacs for Bajirao. A  centralized monarchy might have changed history. Overall, he gave the  Maratha state stability, secured its freedom and opened prospects for  expansion.
Sir  Jadunath Sarkar attempts to give an explanation for Bajirao’s  failure to restore Hindu sovereignty over parts of India from where  they extracted tribute. "The Peshwa's work was that a conqueror  not a consolidator. He was a matchless cavalry leader but no  statesman, no far-sighted reformer." 
At end of  article read “Why Bajirao is India's  greatest cavalry general?” Excerpts - “In  his brief military career spanning 20 years, Bajirao never lost a  battle.
A keen and dashing horseman, Bajirao  organised the Marathas into an efficient fighting machine based on  the concept of fast moving cavalry. His army was composed solely of  cavalry with virtually no baggage train to slow it down.
Bajirao lived with his soldiers, shared  their hardships and always led from the front.
An appreciative and shrewd commander,  he gathered around him competent men like Shinde, Holkar, Gaekwad,  Pawar and Jadhav.
In 1739, instigated by  some Mughal courtiers, Nadir Shah invaded India. He was helped in the  Punjab by the Nizam and other Mughals who wanted the Marathas to be  ousted from Delhi at all costs. Nadir Shah obliged them and in the  bargain looted wealth worth nearly Rs 100 crore. He also took away  with him the famous Peacock Throne as well as the Kohinoor diamond.
One of the  big 'ifs' of Indian history is Bajirao's untimely death on the way to  Delhi to take on Nadir Shah. Maybe the Kohinoor and Peacock Throne  would have still been in India."
While  encamped at Raverkhedi 36 miles from Khargon, Baji Rao got fever and  died on 28th April 1740.”
