Kediri
In 1042 before retiring as a hermit, Airlangga split his kingdom between his two sons. Of the two kingdoms Daha (at Kediri) and Janggala (near Surabaya) the former was to thrive through 1222. The Daha kingdom boasts the important king Jayabaya, whose prophesies remain popular right through the present day. Jayabaya also commissioned a Javanese version of the Bharatayudha in 1157.
Daha was ultimately brought down by a rebellious province. Ken Arok, was an upstart who gained the power over Tumapel, a fiefdom east of Kawi, and then gradually extends it by gobbling up parts of the old Janggala kingdom. As he consolidated his power he rebelled against Kediri and proceeded to ask its obeisance. Ken Arok takes power as king Rajasa, and with him starts the Singasari dynasty.
We know of no temple remains from this era. Kediri does have temples from the Majapahit era, that are listed in the Majapahit section. .
