The Singhasari Kingdom was a significant Hindu-Buddhist kingdom in East Java, Indonesia, that thrived from the late 13th century to the early 14th century. Founded by Ken Arok, it is known for its military conquests and cultural achievements, including the construction of impressive temples and monuments. The kingdom played a crucial role in the spread of Hinduism and Buddhism in the region. The kingdom reached its peak under the rule of Kertanegara, who expanded its territory and influence. Singhasari is often recognized for its artistic contributions, particularly in sculpture and architecture, which laid the groundwork for the later Majapahit Empire.
