The Armenian alphabet was introduced by Mesrop Mashtots and Isaac of Armenia (Sahak Partev) in 405 CE. Medieval Armenian sources also claim that Mashtots invented the Georgian and Caucasian Albanian alphabets around the same time. However, most scholars link the creation of the Georgian script to the process of Christianization of Iberia, a core Georgian kingdom of Kartli. The alphabet was therefore most probably created between the conversion of Iberia under Mirian III (326 or 337) and the Bir el Qutt inscriptions of 430, contemporaneously with the Armenian alphabet.
