Mangkunegara II, also known as Prince Adipati Prangwedana I, Prince Surya Mataram, Prince Surya Mangkubumi, (born Bendara Raden Mas Sulama, 5 January 1768 – 17 January 1836) was the second ruler of Mangkunegaran in Java in the eighteenth century who succeeded to the throne of his grandfather, Mangkunegara I. His reign lasted from 1796 to 1835. Mangkunegara II was the son of Crown Prince Arya Prabumijaya I, who was the son of Mangkunegara I. Upon his death in 1835, he was the last male descendant Prince Sambernyawa to be named the Duke of Mangkunegaran. Family Kanjeng Gusti Pangeran Adipati Arya Mangkunegara II came from Prabumijaya I family, born to Crown Prince Arya Prabumijaya I and Princess Alit. He was a grandson of both Mangkunegara I and Pakubuwana III, paternally and maternally respectively. This dynasty had a tradition of being strongly militaristic. He became Duke in Mangkunegaran, replacing his grandfather who had died in 1795. As a youth in the care of his grandfather, Mangkunegara I had been prepared for the succession to the royal throne which had been diverted from his father Crown Prince Arya Prabumijaya I who died before his father Mangkunegara I. Boundary disputes with neighboring areas increased tensions which led to open warfare. With the experiences of his youth in the direct care of his grandfather, Mangkunegara II subsequently grew to become a leader in the legendary style of his grandfather. He was the last ruler of Mangkunegaran from Patrilineal descendant of Mangkunegara I. Government While Mangkunegara II was ruler in the Duchy of Mangkunegaran, his administration was preoccupied with war and territorial expansion. Mangkunegara's administration tended to be active and expansive. It played a role in dealing with the colonial power and relations with the other powers in Java. Expanding the empire During the reign of Mangkunegara II, Mangkunegaran expanded from 4,000 to 5,500 households. In the year 1808, the Legion Mangkunegaran was formed with 1,150 armed personnel to strengthen the position of Mangkunegaran. The use of the word "Legion" for the army reflects the Mangkunegaran absorption of new ideas from Europe through Daendels, who served as Governor-General in Dutch East Indies.
