Mysore Dasara is the Nadahabba (state-festival) of the state of Karnataka in India. It is also called Navaratri (Nava-ratri = nine-nights) and is a 10-day festival with the last day being Vijayadashami, the most auspicious day of Dasara. Dasara usually falls in the month of September or October. According to a legend, Vijayadashami denotes the victory of truth over evil and was the day when the Hindu Goddess Chamundeshwari killed the demon Mahishasura. Mahishasura is the demon whose slaying by the Goddess gave the name Mysore. The city of Mysore has a long tradition of celebrating the Dasara festival with utter grandeur and pomp to mark this day and the festivities there are an elaborate affair, attracting a large audience including foreigners. The Dasara festival completed 400th anniversary in year 2010.
The Dasara festivities began with the Vijayanagar kings as early as the 15th Century. A Persian ambassador, Abdur Razzaq, reported the Dasara observance (originally Mahanavami) in Vijayanagara during his mission to India in his book entitled Matla-us-Sadain wa Majma-ul-Bahrain (The Rise of the Two auspicious constellations and the Confluence of the Two Oceans), a major work which contained an overview of the history of this part of the world from 1304 to 1470.
After the fall of the Vijayanagar kingdom, the Wodeyars of Mysore continued the Dasara Festival, initially by Raja Wodeyar I (1578-1617 CE) in the year 1610 at Srirangapatna. The Mysore Palace is illuminated on all the 10 days of Dasara. Chamundi Hill at Mysore. This would be followed by a special durbar (royal assembly). It was during the reign of Krishnaraja Wodeyar III in the year 1805, when the king started the tradition of having a special durbar in the Mysore Palace during Dasara; which was attended by members of the royal family, special invitees, officials and the masses. After the death of Srikanta Wadiyar in December 2013, this tradition has been continued by placing the “Pattada Katti” (royal sword) on the golden throne. The ninth day of Dasara called as Mahanavami is also an auspicious day on which the royal sword is worshipped and is taken on a procession involving elephants, camels and horses.
