The ruling Congress began celebrating the birth anniversary of the 18th century Mysore ruler on November 10 since 2015 to honour him as a patriot and remember his yeoman service to the people in the region.

Eldest son of Sultan Hyder Ali, Tipu (1750-1799) is also hailed as the "Tiger of Mysore" for fighting against the British East India Company to protect and enlarge his kingdom.

Tipu was killed in a battle with the British Army in 1799 while defending his fort at Srirangapatnam near Mysore, about 120km from Bengaluru.

Tipu's 267th birth anniversary is also being celebrated with special functions at his birth place in Devanahalli village on Bengaluru outskirts and in cities and towns that were part of his kingdom in the Deccan region.

In the state capital, Chief Minister Siddaramaiah will inaugurate the event titled "Hazarath Tipu Sultan Jayanthi" at 6.30 p.m. at Vidhana Soudha, the state secretariat, in the presence of dignitaries and invitees.

To prevent a repeat of violent protests that claimed one life in 2015, the police imposed a ban order under section 144 of the Criminal Procedure Code (CrPC) at Madikeri town in Kodagu district, about 270km from here.
