The Regreg War (often erroneously called the Paregreg) was a civil war that took place in 1404–1406 within the Javanese empire of Majapahit. The conflict was fought as a war of independence between the Kedhaton Kulon (Western court) led by Wikramawardhana against the breakaway Kedhaton Wetan (Eastern court) of Blambangan led by Bhre Wirabhumi. This war of rivalry and secession had caused calamity, crisis, court's preoccupation, the drain of financial resources, and exhaustion, which is thought to be one of the causes of Majapahit's decline in the following years.
