Wengker
Wengker was an old polity in the inland country around Ponorogo in eastern Java. Its name appears in accounts of the struggles of Airlangga, the eleventh-century ruler who restored royal power after the collapse of his predecessor's realm. The ruler of Wengker challenged him more than once, including a rebellion in 1035. The area's later traditions of Bantarangin and the dance-drama Reog preserve memories of a Javanese past in which local rulers contested the authority of greater courts.
