The reign of Vramshapuh is most noted under his patronage for Mesrop and Sahak for presiding over the creation of the
Armenian alphabet in 405 to 406. The creation of the Armenian alphabet brought a last moment of glory to the Arsacids and Vramshapuh sent Sahak to the Sasanian court in Persia to conciliate over the creation of the alphabet. Vramshapuh became interested in the project and he was materially and morally the literacy project's great patron. The Armenian alphabet was a tool to greater unify Armenians living in the Byzantine Empire and the Sasanian Empire, giving a Christian identity to the Armenian people. The alphabet was the key to the survival of the Armenian culture and identity, providing the cohesive forces in society with a standard around which to rally. In time the Armenian language would become the native language of the Armenians, used throughout the country and the language was invented from Greek, Syriac and Persian scripts. The important role of the Armenian language at that time was to propagate the Christian religion. At that time the church scriptures in Armenia were read in Greek and Syriac. The majority of the people couldn't understand the scriptures being read in these languages. The creation of the Armenian alphabet during Vramshapuh's reign marks a symbolic time in the country's history leading to prominent flowering of Armenian literature, later called the
Golden Age of Armenian Literature. After the creation of the Armenian alphabet, Vramshapuh providing counsel, funds and assistance to the project, supported Mesrop and Sahak in carrying out educational missions in teaching the Armenians the new language. This led Armenians to better understand Christianity and the reading of the scriptures, in particular the preaching of Christianity in pagan sections of the country. After this moment, little is known about the remaining years of Vramshapuh's reign. He died in 417 leaving a son, Artaxias IV, with a mother whose name is unknown. At the time, Artaxias IV was too young to succeed his father. After the death of Vramshapuh, Sahak visited the court of the Sasanian shah Yazdegerd I in releasing Khosrov IV from political exile. Yazdegerd I consented with Sahak in releasing Khosrov IV from imprisonment. When Khosrov IV was released from political exile, there is a possibility he may have served again as king of Armenia from 417 until about 418. The possible second reign of Khosrov IV, may have only lasted up to a year, as he died in 418. From 417 til 422 Armenia was under direct rule of the
Nakharars and the Sasanian dynasty. In 422 Artaxias IV was appointed King of Armenia by the Sasanian dynasty. ==Commemorative coinage==
