Kyai Maja, Javanese ulama and commander of Java War (born 1792)

Muslim Mochammad Khalifah, better known as Kyai Maja, was a Javanese ulama and spiritual leader best known for his role as a key commander and religious adviser of Diponegoro during the Java War. He was a key commander of the rebels until his surrender in late 1828, and he was later exiled to Tondano where he died in 1849.

The Java War, also known in Indonesia as the Diponegoro War, was an armed conflict in central and eastern Java from 1825 to 1830, between native Javanese rebels headed by Prince Diponegoro and the Dutch East Indies supported by Javanese princely states. It is considered a watershed in Javanese history, culture, and society.
