The exact date of Hyder Ali's birth is not known with certainty. Various historical sources provide dates ranging between 1717 and 1722 for his birth.
[4] There are also some variations in reports of his ancestry. According to some accounts, his grandfather was descended from a line of
Sayyids tracing their lineage back to
Persia,
[5] while another traces his lineage instead to the area of present-day
Afghanistan.
[5] In a third account, written by one of his French military officers, Hyder himself claimed descent from the
Bani Hashim Clan of
Quraysh tribe of
Arabs, the tribe of
Muhammad through his ancestor Sayyid walSharif Hassan bin Yahya who was the
Sherif of Makkah.
[6] His father,
Fath Muhammad, was born in
Kolar, and served as a commander of 50 men in the
bamboo rocket artillery (mainly used for signalling) in the army of the
Nawab of Carnatic.
[7] Fath Muhammad eventually entered the service of the
Wodeyar Rajas of the
Kingdom of Mysore, where he rose to become a powerful military commander. The Wodeyars awarded him
Budikote as a
jagir (land grant), where he then served as
Naik (Lord).
[4] Hyder Ali was born in Budikote; he was
Fath Muhammad's fifth child, and the second by his third wife.
[4] His early years are not well documented; he entered military service along with his brother Shahbaz after their father died in combat.
[8] After serving for a number of years under the rulers of
Arcot, they came to
Seringapatam, where Hyder's uncle served. He introduced them to Devaraja, the
dalwai (chief minister, military leader, and virtual ruler) of
Krishnaraja Wodeyar II, and his brother Nanjaraja, who also held important ministerial posts.
[9] Hyder and his brother were both given commands in the Mysorean army; Hyder served under Shahbaz, commanding 100 cavalry and 2,000 infantry
