The third stream is a large, powerful indigenous Javanese Christian movement under the leadership of Ibrahim Tunggul Wulung. Tunggul Wulung was a scion of the royal family of Solo in Central Java who became a hermit mystic on Mount Kelut in East Java. From there, through an interesting series of events he became a Christian believer who identified himself as a "Kristen Jowo" (Javanese Christian) who sought to retain Javanese language, culture and folkways, in contrast to the so-called "Kristen Londo" (Dutch Christian), converts to Christianity who tended to adopt European ways. This indigenous movement grew far more rapidly than the Christian groups begun by European missionaries.
