Prince Diponegoro of Yogyakarta led the Java War (1825-30), but his career as a rebel leader came to a sudden halt when he was tricked into going to the Dutch headquarters to negotiate peace, was taken prisoner and then exiled to Sulawesi. He spent the last 26 years of his life imprisoned in Fort Rotterdam. His tomb and monument can be seen in a small cemetery, Makam Pangeran Diponegoro.
