Wulung is a city located in Indonesia. While specific geographical details are limited in the provided records, it is situated within a region where significant religious history occurred during the 19th century.
The area is historically associated with the work of Ibrahim Tunggul Wulung (1800–1885), an indigenous evangelist. He was active across several provinces, including East Java, Central Java, West Java, and Banten, where he began evangelizing the Javanese people in the early 1800s.
During this period, the development of Christianity in Java involved a combination of Dutch lay evangelists and indigenous figures. Ibrahim Tunggul Wulung worked alongside other notable individuals such as Kyai Sadrach, Paul Tosari, F. L. Anthing, and C. V. Stevens-Phillips.
