Shivappa Nayaka was a notable ruler of the Keladi Nayaka Kingdom from 1645-1660. The Keladi Nayakas were successors to the Vijayanagara Empire and built a niche kingdom in coastal and hill regions of Karnataka before succumbing to the Kingdom of Mysore in 1763. Shivappa Nayaka introduced a new tax system called "Sist" and commissioned notable temples in the styles of local South Indian dynasties, including the Aghoreshwara temple at Ikkeri and Rameshwara temple at Keladi. These temples blended Vijayanagara and local styles, featuring pillars depicting mythological figures.

7. Decline and the end
 For more than two hundred years the kingdom
controlled the coastal and malnad regions of
present-day Karnataka and fostered a rich tradition
of trade with the English, the Portuguese, and the
Dutch. However, in the period of gloom brought
about by the fall of the last great Hindu empire, the
Vijayanagar empire, constant wars—campaigns
against local chieftains and the Mysore Kingdom and
the harassment of the Marathas finally drained the
treasury and resulted in the end of the kingdom.

10. Architecture of keladi Nayaka History
 The Keladi Nayakas built some fine temples in Ikkeri and Keladi
using a combination of late Kadamba, Hoysala, Vijayanagar,
and Dravida styles. The use of granite for their construction shows
they simply followed the Vijayanagar model of architecture. The
Aghoreshwara temple at Ikkeri and the Rameshwara temple at
Keladi are the best examples of the Nayakas' art. Vijayanagar-style
pillars with hippogryphs are common; called yali columns
(depiction of horses and lions as seen in Hampi) is found here.
These are pillars with lions, either with their forepaws raised or
simply in a sitting position, and pillars with a mythical horse-like
animal with front legs raised, balancing on its rear legs, and with an
armed rider on its back which are worth seeing at Ikkeri. A roof
sculpture depicting a Gandaberunda, the mythical two-headed bird
of Karnataka, is found in Keladi. Also, in the Rameshwara temple, a
pillar sculpture shows Maratha Rajaram with Keladi Chennamma
(history has it that Rajaram was protected by the queen when he
was on the run from the Mughals).
