Tigranes (sometimes Tigran or Dikran; ; ) was the name of a number of historical figures, primarily kings of Armenia.
The earliest Tigranes is mentioned in the Cyropaedia and in Armenian historical sources. He was an Armenian king from the Orontid Dynasty and an ally of Cyrus the Great. One of his sons was also named Tigranes. This son is usually assumed to have succeeded his father, but nothing is known about him.
By far the best known Tigranes is Tigranes the Great, king of Armenia from 95 to 55 BC, who founded a short-lived Armenian empire. His father, who ruled from 115 to 95 BC, was also named Tigranes, as were several later kings of Armenia. There is some lack of consistency in assigning dynastic numbers to these kings. The earliest Tigranes and his son are usually not included, making Tigranes I the father of Tigranes the Great. However, Tigranes the Great is also sometimes known as Tigranes I, in his capacity as a successor to the Seleucid dynasty.
Another Tigranes was a member of the Achaemenid family who, according to Herodotus, commanded the Medes in the army of Xerxes during the invasion of Greece. Tigranes is the Hellenized form of the name, found in classical sources. Tigran and Dikran are closer to local Armenian usage.
The satirist Lucian, in his True History, describes Homer (probably 8th century BC) as a Babylonian called Tigranes, who assumed the name Homer when taken "hostage" (homeros) by the Greeks.
Tigranes was an Armenian Prince of the Arsacid dynasty of Armenia who lived in the second half of the 4th century and possibly first half of the 5th century.
According to modern genealogies, Tigranes was a son born to the Armenian Monarchs Khosrov IV and Zruanduxt, while his brother was Arsaces. The father of Tigranes, Khosrov IV was an Arsacid Prince who was the first Armenian Monarch to serve as a Client King of Eastern Armenia under Sassanid rule who reigned from 387 until 389. His mother Zruanduxt, was a Sassanid Princess from Persia who was the sister of the Sassanid King Shapur III who reigned from 383 until 388.
Tigranes was named in honor of his ancestor Tigranes VII, also known as Tiran and he was also named in honor of the monarchs named Tigranes of the Artaxiad Dynasty. The name Tigranes, was the most common royal name in the Artaxiad Dynasty and was among the most ancient names of the Kings of Armenia. He was born at an unknown date in his father’s kingship and raised in Eastern Armenia. It is unknown whether he became a Christian in faith or a follower of the religion of Zoroastrianism.
In 389 the Sassanid King Bahram IV, dethroned Khosrov IV and placed him in confinement in Ctesiphon. Bahram IV was unsatisfied with Khosrov IV. Bahram IV considered Khosrov IV, as being too assertive in his royal authority as a governing Client Monarch and did various acts in his kingship without consultation from the Sassanid dynasty. Bahram IV in 389 replaced Khosrov IV, with his brother Vramshapuh as Sassanid Client King of Arsacid Armenia. After this moment, the fate of Zruanduxt, Tigranes and Arsaces is unknown.
