Early life

Leo III was born in Germanikeia, Commagene, which is in modern Kahramanmaraş in Turkey. His original name was Konon (Greek: Κόνων; Latin: Conon or Cononus). Leo III was fluent in Arabic, possibly as a native language, and was described by Theophanes the Confessor as "the Saracen minded."

After the victory of Justinian II, Konon was dispatched on a diplomatic mission to Alania and Lazica to organize an alliance against the Umayyad caliphate under Al-Walid I. According to the chronicle written by Theophanes the Confessor, Justinian wanted to get rid of Konon and took back the money that had been given to him to help advance Byzantine interests, thus leaving Konon stranded in Alania. The chronicle describes the mission as successful and Konon returning eventually to Justinian after crossing the Caucasus mountains in May with snowshoes and taking the fortress of Sideron, associated with the Tsebelda fortress, on the way.

Konon was appointed commander (stratēgos) of the Anatolic Theme by Emperor Anastasius II. On his deposition, Konon joined with his colleague Artabasdos, the stratēgos of the Armeniac Theme, in conspiring to overthrow the new Emperor Theodosius III. Artabasdos was betrothed to Konon's daughter Anna.
