Second Carnatic War ( 1749 - 54 )

Background

The background for the Second Carnatic War was provided by rivalry in India. Dupleix, the French governor who had successfully led the French forces in the First Carnatic War, sought to increase his power and French political influence in southern India by interfering in local dynastic disputes to defeat the English. 

Immediate Cause 

The opportunity was provided by the death of Nizam-ul-Mulk, the founder of the independent kingdom of Hyderabad, in 1748 and the release of Chanda Sahib, the son-in-law of Dost Ali, the Nawab of Carnatic, by the  Marathas in the same year. The accession of Nasir Jung, the son of the Nizam, to the throne of Hyderabad was opposed by Muzaffar Jung, the grandson of the Nizam, who laid claim to the throne saying that the Mughal Emperor had appointed him as the governor of Hyderabad. In the Carnatic, the appointment of Anwaruddin Khan as the Nawab was resented by Chanda Sahib. 

The French supported the claims of Muzaffar Jang and Chanda Sahib in the Deccan and Carnatic, respectively while the English sided with Nasir Jang and Anwaruddin.

Course of the War 

The combined armies of Muzaffar Jang, Chanda Sahib, and the French defeated and killed Anwaruddin at the Battle of Ambur in 1749. Muzaffar Jang became the subahdar of Deccan, and Dupleix was appointed governor of all the Mughal territories to the south of the river Krishna. A French army under Bussy was stationed at Hyderabad to secure French interests there. Territories near Pondicherry and also some areas on the Orissa coast were ceded to the French. 

Having failed to provided effective assistance to Muhammad Ali at Trichinopoly, Robert Clive, then the agent of the English company, put forward the proposal for a diversionary attack on the governor of Madras, Saunders. He suggested a sudden raid on Arcot, the capital of the Carnatic, so as to relieve the pressure on Trichinopoly. He reasoned that in such an event Chanda Sahib would rush to save his capital. Thus, in August 1751, with only a force of 210 men, Robert Clive attacked and captured Arcot. As expected, Chanda Sahib hastened to his capital, taking a force of 4,000 men from Trichinopoly, but failed to get back the fort even after a siege of 53 days, from September 23 to November 14. Now Mysore, Tanjore and the Maratha chief, Morari Rao, came to the aid of Trichinopoly, and of Clive and Stringer Lawrence. Trichinopoly was first relieved of its siege, while General Law of French with Chanda Sahib remained cooped up in the island of Srirangam. They were forced to surrender in June 1752 when Muhammad Ali executed Chanda Sahib, the British failing to interfere.

result 

The French authorities, annoyed at the heavy financial losses that Dupleix's policy involved, decided to recall him in 1754. Godeheu succeeded Dupleix as the French governor general in India. Godeheu adopted a policy of negotiations with the English and concluded a treaty with them. The English and the French agreed not to interfere in the quarrels of native princes. Also, each party was left in possession of the territories actually occupied by them at the time of the treaty. According to historians, the fear of serious repercussions in America prompted the French to suspend hostilities in India.

Implications 

It became evident that the countenance of Indian authority was no longer necessary for European success; rather Indian authority itself was becoming dependent on European support. Muhammad Ali in the Carnatic and Salabat Jang in Hyderabad became clients rather than patrons.
