Mataram Hindu/Budha
The Ancient Mataram Kingdom itself was once under the rule of 3 dynasties. The three dynasties are the Sanjaya House, the Syailendra House and the Isana House. The Sanjaya dynasty itself is a follower of the Shiva religion of Hinduism, the Syailendra dynasty is a follower of Buddhism. Meanwhile, the Isana dynasty was a new dynasty founded by Mpu Sindok. The first king to lead the Ancient Mataram Kingdom was King Sanjaya. Sanjaya was the founder of the Sanjaya Dynasty which adhered to Hinduism. Subsequently, Sanjaya was replaced by Rakai Panangkaran who converted to Mahayana Buddhism. That's when the Isana dynasty became powerful. However, Hinduism and Buddhism developed together.
History of The Ancient Mataram Kingdom
The Ancient Mataram Kingdom is located in the Bogowonto, Elo, Progo and Bengawan Solo river basins, Central Java. Ancient Mataram was led by Sana, then after Sana died leadership fell to Sanjaya, his nephew. At the same time, the leadership of Sri Maharaja Rakai Panangkaran in Central Java established a new dynasty that embraced Buddhism, namely the Syailendra dynasty. The development of this dynasty pushed aside the position of the Sanjaya dynasty that embraced Hinduism. And in order to strengthen power, the two dynasties merged. Namely by marrying Princess Pramodhawarni (Syailendra) and Rakai Pikatan (Sanjaya).
