After Sultan Agung, the Sultanate of Mataram was declining due to power struggle within the sultanate. To make things worse, VOC (Dutch East India Company) exploited the power struggle to increase its control. At the peak of the conflict, the Mataram Sultanate was split in two based on the Treaty of Giyanti of 13 February 1755: Yogyakarta Sultanate and Surakarta Sunanate. During the era of Dutch occupation there were two principalities, the Yogyakarta Sultanate (Kasultanan Yogyakarta) and the smaller Pakualaman Duchy / Principality (Kadipaten Pakualaman).
2. Borobudur Buddha Temple
This famous Buddhist temple, dating from the 8th and 9th centuries, is located in central Java. It was built in three tiers: a pyramidal base with five concentric square terraces, the trunk of a cone with three circular platforms and, at the top, a monumental stupa. The walls and balustrades are decorated with fine low reliefs, covering a total surface area of 2,500 m2. Around the circular platforms are 72 openwork stupas, each containing a statue of the Buddha. The monument was restored with UNESCO's help in the 1970s.

Built in the 10th century, this is the largest temple compound dedicated to Shiva in Indonesia.
