At the time, Rome was fighting the Jugurthine and Cimbric wars. Mithridates and Nicomedes of Bithynia both invaded Paphlagonia and divided it amongst themselves. A Roman embassy was sent, but it accomplished nothing. Mithridates also took a part of Galatia that had previously been part of his father's kingdom and intervened in Cappadocia, where his sister Laodice was queen. In 116 the king of Cappadocia, AriarathesVI, was murdered by the Cappadocian noble Gordius at the behest of Mithridates, and Laodice ruled as regent over the sons of Ariarathes until 102BC. After Nicomedes III of Bithynia married Laodice, he tried to intervene in the region by sending troops; Mithridates swiftly invaded, placing his nephew Ariarathes VII of Cappadocia on the throne of Cappadocia. War soon broke out between the two, and Mithridates invaded with a large Pontic army, but AriarathesVII was murdered in 101BC before any battle was fought. Mithridates then installed his eight-year-old son, Ariarathes IX of Cappadocia as king, with Gordius as regent. In 97 Cappadocia rebelled, but the uprising was swiftly put down by Mithridates. Afterwards, Mithridates and NicomedesIII both sent embassies to Rome. The Roman Senate decreed that Mithridates had to withdraw from Cappadocia and Nicomedes from Paphlagonia. Mithridates obliged, and the Romans installed Ariobarzanes in Cappadocia. In 91/90BC, while Rome was busy in the Social War in Italy, Mithridates encouraged his new ally and son-in-law, King Tigranes the Great of Armenia, to invade Cappadocia, which he did, and Ariobarzanes fled to Rome. Mithridates then deposed NicomedesIV from Bithynia, placing Socrates Chrestus on the throne.
