He was the son of Haider Ali, ruler of Mysore and Fakhr-un-Nissa and died fighting the English, being considered a national hero in India for his long time struggle against the British colonial forces in India who aimed at subduing and eventually annex his states.
A capable administrator, poet and military leader and a devout Muslim, Tippu Sultan was an example of tolerance towards other religions, protecting Hindu temples and having built the first Christian church in Mysore.
Tippu Sultan died in battle defending his capital Srirangapattana.
Detailed biographies can be found at The Sword of Tippu Sultan, by Dr. K. L. Kamat and in the Website dedicated to Tipu Sultan and at Wikipedia http://en.wikipedia.org/wiki/Tipu_Sultan.
Tippu Sultan left a splendid library rich in manuscripts and books on government, law, religion and the sciences which was plundered by the British army after his defeat at Srirangapattana (more... in Lost treasures - Seema Alavi - Assistant Professor, Jamia Millia Islamia, New Delhi).
It is also known that «Tipu used to put his signature and stamp on every book he read. Most of the books in his library bore his signature and stamp. He used to put his signatures in an artistic and intricate style. First, he used Tipu Sultan as his name ‘Nabi Malik’. According to Kirk Patrick, the British supervisor of the library appointed by the Company, his wittings were superior to others and exceptionally lucid and compact» (quoted from http://taher.freeservers.com/tipuSultanLibrary.htm).
On the whereabouts of Tipu Sultan’s library, see:
«Oriental & India Office Collections (OIOC) section of the British Library in London - The nucleus of the collection itself was from the private Library of Tipu Sultan of Mysore, who had built it from the treasures of various Indian rulers conquered by himself and his father Hyder Ali. After the British defeated Tipu Sultan, this library of 2000 manuscripts was divided between the Cambridge and Oxford Universities in Britain and the College of Fort William in Calcutta. Meanwhile Robert Orme, the historiographer of the East India Company had collected a large number of manuscripts, books and letters during his career and requested the East India Company to create ‘a repository for Oriental Writings.» (quoted from http://taher.freeservers.com/tipuSultanLibrary.htm);
