Hyder Ali (1722–1782), also known as Sultan Hyder Ali Khan Bahadur, was a prominent ruler and military commander who founded the Kingdom of Mysore in southern India. He served as the de facto ruler of Mysore from 1761 until his death in 1782, and his military innovations and strategic prowess made him a significant figure in Indian history. Hyder Ali is often credited with introducing the use of rocket artillery in warfare, which was later adopted by other military powers. In Hebrew, his name is translated as הידר עלי. In Urdu, he is known as حیدر علی, and in Kannada, one of the primary languages of Mysore, he is referred to as ಹೈದರ್ ಅಲಿ. Hyder Ali's reign was marked by his efforts to modernize Mysore's military and administrative systems, as well as his conflicts with the British East India Company, which laid the groundwork for future Anglo-Mysore wars.
