"Pacorus II (also spelled Pakoros II; 𐭐𐭊𐭅𐭓) was the King of Kings of the Parthian Empire from 78 to 110. He was the son and successor of Vologases I (r. 51–78).
During the latter part of his father's reign, Pacorus ruled the Parthian Empire along with him. After Vologases I's death in 78, Pacorus became the sole ruler, but was quickly met by a revolt by his brother Vologases II, which lasted until the latter's defeat in 80. In 79/80, Pacorus' rule was contended by another Parthian prince—Artabanus III—whom he had defeated by 81. A third Parthian contender, Osroes I, appeared in 109. The following year, Pacorus was succeeded by his son Vologases III, who continued his father's struggle with Osroes I over the Parthian crown." - (en.wikipedia.org 11.08.2021)
