Sultan Hamengkubuwana IV

Sultan Hamengkubuwana IV, who ruled from 1810 to 1820, was a significant figure in Javanese history, particularly noted for his role during the early years leading up to the Java War (Perang Jawa). His reign was marked by the implementation of controversial taxation policies that contributed to widespread dissatisfaction among the Javanese populace, ultimately setting the stage for the larger uprising led by figures like Pangeran Diponegoro.
