Tipu Sultan (born Sultan Fateh Ali Sahab Tipu, 20 November 1750 – 4 May 1799), also known as "Tipu Sahab" or the Tiger of Mysore, was the ruler of the Kingdom of Mysore based in South India and a pioneer of rocket artillery. He introduced a number of administrative innovations during his rule, including a new coinage system and calendar, and a new land revenue system which initiated the growth of the Mysore silk industry. He expanded the iron-cased Mysorean rockets and commissioned the military manual "Fathul Mujahidin". He deployed the rockets against advances of British forces and their allies during the Anglo-Mysore Wars, including the Battle of Pollilur and Siege of Seringapatam.
