Personal life
Mangkunegara was given the nickname "Life Reaping Prince" by Nicolaas Hartingh because the prince had brought his enemies to death during the war. Hatingh was the Dutch East India Company's Governor of the Northeast Coast of Java, located in Batavia.
Raden Mas Said was born on 7 April 1726 in Kartasura. Mangkunegara was brought up by his mother, Raden Ayu Wulan and his father, Prince Mangkunegara of Kartasura. His father was the eldest son of Amangkurat IV born to a concubine, Mas Ayu Sumanarsa of Nglaroh (also known as Mas Ayu Karoh), and by his princely title of Kanjeng Gusti Pangeran Adipati Arya Mangkunegara, he was the crown prince of Mataram. His maternal grandfather was Kanjeng Gusti Pangeran Adipati Arya Blitar, younger brother of Amangkurat IV. Thus, his parents were first paternal cousin.
In 1747 (1642 AJ), he married Raden Ajeng Inten or Raden Ajeng Bruwok, daughter of Hamengkubuwana I. She was later styled Gusti Kanjeng Ratu Bendara upon her father's ascension.
He was in-law with Pakubuwana III as his eldest son, Kanjeng Pangeran Harya Prabuwijaya, born to Raden Ayu Matahati of Nglaroh, wed his daughter.
