Pap
Arsacid Dynasty — 370–374 AD
Arsacid Dynasty
Pap reigned from 370 to 374 AD as the monarch of the Kingdom of Armina (Greater Armenia), succeeding his father, Arshak II. Installed on the throne with Roman assistance following a period of Sasanian occupation, he led a national resurgence alongside the sparapet Mušeł Mamikonian. His early reign was defined by the decisive victory over the Sasanian King Shapur II at the Battle of Djirav in 371 AD, which restored the kingdom’s independence and reclaimed lost provinces such as Utik, Gugark, and Aghdznik. His internal rule was marked by radical reforms aimed at centralizing royal power and increasing the state’s military and demographic strength. Pap reorganized the Armenian army into a professional force of 100,000, seized extensive church lands to fund the treasury, and established the independence of the Armenian Church by ending the practice of consecrating Catholicoi in Caesarea. These independent policies eventually alienated the Roman Empire, leading to his treacherous assassination by the Roman general Trajanus during a banquet in 374 AD.
The reign of Pap began amidst the "miserable situation" following the arrest of his father, Arshak II. While his mother, Queen Parandzem, held the fortress of Artagers against a Persian siege, Pap sought Roman military aid from the Emperor Valens. Returning to the highlands with the sparapet Mušeł Mamikonian, he unified the Armenian forces and faced the Sasanian Empire at the Battle of Djirav in 371 AD. Supported by Roman contingents, the Armenian army crushed the Persian coalition, leading to the execution of the traitor Meruzhan Artsruni and the recognition of Pap’s throne by Shapur II. Following this triumph, Mušeł Mamikonian systematically recaptured the traditional border provinces, restoring the kingdom’s boundaries to the scale they had reached during the eras of Artaxias the Pious and Tigranes the Great.
The Radical Reformer and the Church
Domestically, Pap sought to transform the socio-economic fabric of the Kingdom of Armina (Greater Armenia). He recognized that the church’s vast landholdings and monastic structures were depleting the state's military resources and slowing population growth. In response, he shuttered nunneries and forced residents to marry or join the army, while simultaneously seizing church-owned lands to redistribute to the military. This led to a bitter conflict with Catholicos Nerses the Great. Pap further asserted Armenian sovereignty by decreeing that future Catholicoi, beginning with Shahak of Manazkert, must be ordained within Armenia rather than in Caesarea. Though his reforms were viewed as "sinful" by the clergy, they successfully financed a professional royal army of 100,000 soldiers.
The Tarsus Conspiracy and the Final Feast
The final chapter of Pap’s reign was a struggle for complete independence from Roman political oversight. Resenting the interference of the Roman commander Terentius, Pap initiated secret negotiations with Shapur II. When the Roman authorities discovered this link, Emperor Valens lured Pap to Tarsus under the pretext of a summit, attempting to place him under arrest. The king escaped with 300 bodyguards and returned to the highlands, only to face a second plot orchestrated by the commander Trajanus. In 374 AD, Trajanus invited the king to a royal banquet and murdered him during the feast. The Roman historian Ammianus Marcellinus described the scene as an "unjust deed" that saw a guest's blood spattered upon the magnificent tables of hospitality, ending the life of a monarch who had dared to pursue a policy of "sea to sea" sovereignty.
