Hyder Ali (Haidar'alī; حيدرعلى; Kannada: [hɐi̯d̪ɐr ɐliː] c. 1720 – 7 December 1782) was the Sultan and de facto ruler of the Kingdom of Mysore in southern India. Born as Hyder Ali, he distinguished himself as a soldier, eventually drawing the attention of Mysore's rulers. Rising to the post of Dalavayi (commander-in-chief) to Krishnaraja Wodeyar II, he came to dominate the titular monarch and the Mysore government. He became the de facto ruler, King of Mysore as Sarvadhikari (Chief Minister) by 1761.[3] During intermittent conflicts against the East India Company during the First and Second Anglo–Mysore Wars, Hyder Ali was the military leader.
Though illiterate, Hyder Ali concluded an alliance with the French, and used the services of French workmen in raising his artillery and arsenal. His rule of Mysore was characterised by frequent warfare with his neighbours and rebellion within his territories. This was not unusual for the time as much of the Indian subcontinent was then in turmoil. He left his eldest son, Tipu Sultan, an extensive kingdom bordered by the Krishna River in the north, the Eastern Ghats in the east and the Arabian Sea in the west.[4]
Both Haidar 'Ali and Tipu Sultan were parvenu Sunni Muslim rulers...
