succeed him, his adopted son, the apparent heir, was enthroned. But he was killed a few months later by the Dalavayis. Chikkanna Nayaka (1676), the brother of Madakari Nayaka II, served on the throne. His brother succeeded him in 1686 with the title Madakari Nayaka III. The Dalawayis overthrow of Madakari Nayaka III's rule gave an opportunity to one of their distant relatives, Bharamappa Nayaka, to ascend the throne in 1689. He is known as the greatest of the Nayaka rulers. The subjects of Chitradurga suffered through the brief reigns of the successive rulers, which resulted in volatile conditions. The Hiri Madakari Nayaka IV (1721), Kasturi Rangappa Nayaka II (1748), Madakari Nayaka V (1758) ruled this area, but there is not much documentation of their rule. Legend of Onake Obavva During the reign of Madakari Nayaka, the town of Chitradurga was besieged by troops of Hyder Ali. A chance sighting of a woman entering the Chitradurga fort through an opening in the rocks led to a clever plan by Hyder Ali to send his soldiers through the hole. The guard on duty near that hole had gone home for lunch. Obavva, the wife of that guard, was passing by the hole to collect water, when she noticed soldiers emerging into the fort. Obavva was carrying an Onake (a long wooden club meant for pounding paddy grains). She killed Hyder Ali's soldiers one by one as they attempted to enter the fort through the opening and moved the dead. Over a short period of time, hundreds of soldiers entered and fell, without raising any suspicion. After returning from lunch, Obavva's husband was shocked to see Obavva standing with a blood-stained Onake and hundreds of dead enemy bodies around her. Together both wife and husband beat up most of the soldiers. But as both were about to finish off the soldiers, Obavva died. The opening in the rocks remains as a historical marker for this account. The Tanniru doni, the well that Obavva was going to when she saw the invading soldiers, has also survived. Though Obavva saved the fort on that occasion, Madakari Nayaka could not repel another attack in 1779 by Hyder Ali. In the ensuing battle, the fort of Chitradurga fell to the invader. Obavva, like Kittur Rani Chennamma, remains a legend, especially to the women of Karnataka. Geography Chitradurga is located at . It has an average elevation
