Tipu Sultan (20 November 1750  – 4 May 1799), also known as the Tiger of Mysore, was the ruler of the Kingdom of Mysore from 1782 to 1799, and a scholar, soldier and poet. Tipu was the eldest son of Sultan Hyder Ali of Mysore and his wife Fatima Fakhr-un-Nisa, a daughter of Mir Muin-ud-Din, governor of Kadapa. Tipu promoted a more widespread use of Hindustani language in southern India. Tipu introduced a number of administrative innovations, including the introduction of a new coinage, new Mauludi lunisolar calendar[2] and new land revenue system, and initiated the growth of Mysore silk industry.[3] Tipu expanded the iron-cased Mysorean rockets which he deployed in his resistance against military advances of the British.
