Kediri (historical Kingdom)
Kediri or Kadiri (also known as Panjalu) was a Hindu Javanese Kingdom based in East Java from 1042 to around 1222. Despite the lack of archaeological remains, the age of Kediri saw much development in classical literature. Mpu Sedah's Kakawin Bharatayuddha, Mpu Panuluh's Gatotkacasraya, and Mpu Dharmaja's Smaradhana blossomed in this era.
