The battle cemented Arok's control over Eastern Java, and resulted in the ruler founding the Rajasa dynasty.
In the eastern part of the island, agriculture-centric feudal nations (namely the Sailendra, Kediri, Tumapel, and Majapahit kingdoms) intermittently fought over arable land on which to grow rice.
[3] Arok succeeded in aligning his village with the Kingdom of Tumapel, and in doing so became an important adviser the nation's king, Tunggul Ametung.
[5] During the battle, Arok defeated Kertajaya (either by killing him or forcing him to surrender), causing the rout of the Kedirian army.
[6] On the opposing side, the victory of his forces at the Battle of Genter allowed for Arok to establish his own royal line; this lineage became the Rajasa dynasty, which ruled over the Kingdom of Singhasari.
