Prince Diponegoro's Islamic Da'wah: Islamization and Jihad from Selarong Cave to the Java War in Yogyakarta

The purpose of this research is to explain the traces of Prince Diponegoro's Islamic da'wah through Islamization and jihad in the Java War. The background of this struggle is because of the Dutch colonization which carried out arbitrary actions in the palace environment and tried to eliminate the teachings of Islam. The research was carried out with a descriptive-qualitative approach to understand the phenomenology and public perception as a source of primary data. Secondary data sources are published books and research articles as well as archival documents stored in the Prince Diponegoro Museum. The result of the research is that Pangeran Diponegoro conducted Islamic preaching through the process of Islamisation of the followers of kejawen teachings according to the correct sharia. Previously, the Selarong Cave area was a place where Hindu people lived before entering Islam, so the community implemented the teachings of Islam syncretism. While living in Selarong Cave, Prince Diponegoro made war preparations to rally the Javanese community by influencing through his followers, especially from the Islamic community among santri, kiai and ulama as the frontline in facing the Javanese war for five years in Yogyakarta and surrounding areas to Central Java and East Java.
