Title: Ariarathes VIII of Cappadocia
Content:  Ariarathes VIII Epiphanes (, Ariaráthēs Epiphanḗs; reigned c. 101–c. 96 BC and in 95), King of Cappadocia, was the second son of Ariarathes VI of Cappadocia and wife Laodice of Cappadocia. Ariarathes VIII had an older sister called Nysa and an older brother called Ariarathes VII of Cappadocia. Ariarathes ascended to the throne when the Cappadocian nobleman rebelled against his maternal uncle, King Mithridates VI of Pontus and his son, the puppet King Ariarathes IX of Cappadocia. He was speedily driven out of the kingdom by Mithridates VI, and shortly afterwards died a natural death. The death of both sons of Ariarathes VI meant that the Cappadocian royal family was extinct. So Mithridates VI placed upon the Cappadocian throne his own son Ariarathes IX, who was only eight years old. However, King Nicomedes III of Bithynia sent an embassy to Rome to 
Title: Ariarathes IX of Cappadocia
Content:  Ariarathes IX Eusebes Philopator (, Ariaráthēs Eusebḗs Philopátōr; reigned c. 100–85 BC), was made king of Cappadocia by his father King Mithridates VI of Pontus after the assassination of Ariarathes VII of Cappadocia in c. 100 BC. Since he was only eight years old, he was put under the regency of the Cappadocian Gordius. Early in his reign Cappadocian nobility quickly drove him from power in favor of a son of Ariarathes VI of Cappadocia, named Ariarathes VIII of Cappadocia. In 95 BC Mithridates VI of Pontus entered Cappadocia with an army deposing Ariarathes VIII of Cappadocia and restoring his son to 
Title: Ariarathes VII of Cappadocia
Content:  Ariarathes VII Philometor ("mother-loving") (, Ariaráthēs Philomḗtōr; reigned in 116&ndash;101 BC or 111&ndash;100 BC), King of Cappadocia, was the first son of King Ariarathes VI of Cappadocia and his wife Laodice of Cappadocia. Ariarathes VII had an older sister called Nysa and a younger brother called Ariarathes VIII of Cappadocia. In his first years he reigned under the regency of his mother Laodice, the eldest sister of the King Mithridates VI of Pontus. During this period the kingdom was seized by King Nicomedes III of Bithynia, who married Nysa. Nicomedes III was soon expelled by Mithridates VI, who restored upon the throne Ariarathes VII. However, Ariarathes VII objected to his father's assassin, and ally of Mithridates VI, Gordius, having a role in the government of Cappadocia. So Mithridates VI had Ariarathes VII killed in 101 BC. Mithridates VI then put onto the Cappadocian throne his own 9 year old son, Ariarathes IX of Cappadocia, with Gordius as the regent for the young king.
Title: Ariarathes V of Cappadocia
Content:  By Ariarathes' wife Nysa of Cappadocia (who was the daughter of King Pharnaces I of Pontus) he had six children. However, all but one of the children were killed by their mother, so that she might obtain the government of the kingdom. After she had been put to death by the people on account of her cruelty, her only surviving son succeeded to the crown as Ariarathes VI of Cappadocia.
Title: Ariarathes V of Cappadocia
Content:  Ariarathes V Eusebes Philopator (reigned 163–130 BC) was a son of the preceding king Ariarathes IV of Cappadocia and queen Antiochis. He was distinguished by his contemporaries for his excellence of his character and his cultivation of philosophy and the liberal arts and is considered by some historians to have been the greatest of the kings of Cappadocia.
Title: Ariarathes VI of Cappadocia
Content:  He was a child at his succession, and for this reason the power was kept by his mother, who acted as his regent. At some point his mother seems to have poisoned all of Ariarathes’ five brothers; but the infant king was saved by people loyal to the dynasty and had Nysa killed. Using this as a pretext, his maternal uncle, King Mithridates V Euergetes of Pontus (150 BC–120 BC), tried to assert control over the country by marrying Ariarathes to Mithridates' first daughter, Laodice of Cappadocia, who was also Ariarathes' maternal cousin. Laodice bore Ariarathes one daughter and two sons: Nysa who married King Nicomedes III Euergetes of Bithynia; Ariarathes VII Philometor and Ariarathes VIII Epiphanes. Since this wasn't deemed enough to transform Cappadocia in a satellite of Pontus, Mithridates V Euergetes' son, Mithridates VI, murdered Ariarathes using Gordius, a Cappadocian nobleman. On his death the kingdom was briefly ruled by Ariarathes' widow and then seized by King Nicomedes III of Bithynia, who married Laodice, the king's widow. Nicomedes III was soon expelled by Mithridates VI, who placed upon the throne Ariarathes VII.
Title: Ariarathes III of Cappadocia

About 250 BC he was the first ruler of Cappadocia to proclaim himself king (basileus). It is known that he sided with Antiochus Hierax in his war against Seleucus II Callinicus. Ariarathes is also said to have expanded his kingdom adding Cataonia to his dominions. By his marriage he was the father of Ariarathes IV.

Content:  married to his daughter Laodice in order to bring Cappadocia under his control. Mithridates V's son, Mithridates VI (120–63 BC) then had Ariarathes murdered. Cappadocia was then briefly ruled by Nicomedes III of Bithynia (127– 94 BC), marrying Ariarathenes's widow, Laodice. Mithridates VI then ousted Nicomedes, replacing him with Aríarathes VI's son Ariarathes VII (116–101 BC), his mother Laodice acting as regent. Mithridates also had him killed and replaced with Mithridates own son, as Ariarathes IX (101–96 BC). In 97 BC there was a rebellion against this proxy monarchy and Ararathes VII's brother known as Ariarathes VIII was called upon but swiftly dealt with by Mithridates.

Content:  into his kingdom and deposed Ariarathes VII. Mithridates VI swiftly invaded, expelling Nicomedes III from the region, restoring his nephew Ariarathes VII to the Cappadocian throne, and returning Cappadocia to Pontus' sphere of influence. The Pontic king would later have Ariarathes VII murdered in 101 BC, with Mirthridates VI installing his eight-year-old son Ariarathes IX on the Cappadocian throne as his puppet king. As a child, Ariarathes IX was unable to maintain control of the kingdom, with the Cappadocian nobles rebelling against his rule in 97 BC and naming Ariarathes VIII, son of the murdered Ariarathes VII, as king. Mithridates quickly put down the rebellion, exiled Arirarathes VIII, and restored his son to the Cappadocian throne.
