Tirit also known as Tirid (flourished 4th century, died 359) was a Prince from the Arsacid dynasty of Armenia.
Tirit was the son born to Artaxias by an unnamed mother, hence his paternal uncle was Arsaces II (Arshak II) who ruled as Roman Client King of Armenia from 350 until 368 and was a grandson to the previous ruling Roman Client Armenian King Tiran (Tigranes VII) who ruled from 339 until 350.
Tirit was most probably born and raised during the reign of Tiran. His father died at an unknown date during the reign of Tiran. Sometime during the reign of his paternal grandfather, the Sassanid King Shapur II launched a war on Rome and her allies, firstly by persecuting the Christians that lived in Persia and Mesopotamia. Shapur II’s war by capturing these territories began to dealt a severe blow to Roman prestige in the East. Eventually the Sassanid King with his army had invaded Armenia, taking the members of the royal family including Tirit as hostages as they were betrayed to Shapur II by Tiran’s chamberlain. Tirit with all members of his family had become Sassanid political prisoners in which his paternal grandfather was blinded and thrown into prison after Shapur II accused Tiran of collusion with Rome.
The nobles of Armenia were infuriated by the brutality of Shapur II and his treatment of the Armenian royal family, took up arms and fought against Shapur II and his army with assistance from the Romans. They successfully drove Shapur II and his army out from Armenia. After Shapur II was defeated, he had signed a treaty and Tirit with members of his family were released from prison. As Tiran being depressed and blinded from his experience in captivity, had abdicated his throne and Arsaces II succeeded Tiran as Armenian King in 350. During the reign of Arsaces II, Tirit could have been seen as a potential successor to his uncle.
Tirit’s paternal cousin Gnel married an Armenian noblewoman called Pharantzem of Siwnik’ (Siunik) from the Siunia Dynasty. Pharantzem was extremely well known for her beauty and modesty. Her reputation for her beauty had become renown and widespread to the point that Tirit had become passionately in love with her and desired her to be his wife.
