The Roman Emperor, Heraclius accepted Muhammad (S.A.W) as the final messenger of God. You have to understand how intelligent this man was, he was Christian and well studied in Christianity. The true Christian Scriptures, unlike the falsified ones of today, proclaim the Jesus said there will be another prophet after him. That prophet was Muhammad (S.A.W), the seal of the Prophets. Emperor Heraclius believed that Muhammad was the final Prophet but DID express his surprise that he had come from the Arabs as all previous Messengers were from the Hebrews (Jews). Never the less, he accepted Muhammad. The problem is that he knew the people of his empire would reject Muhammad and there would be a revolt. He did however, try to persuade his people to follow Islam. They immediately responded aggressively and tried to break down the doors to his parliamentary building. Seeing this, Heraclius said, "I was only testing your belief in Chrisitianity" It is believed that Heraclius kept his faith a secret. God knows best :) Salaam.

According to Islamic sources, Muhammad sent an "invitation" to King Heraclius of the Byzantine Empire in 628 C.E.The only "invitations" we have in the historical record are those to the King Yazdagerd III of Persia and King Heraclius of the Byzantine Empire performed by Caliph Abu Bakr a year after Muhammad died, in 634 C.E.In both cases, I put "invitation" in quotes since it was a demand letter saying that these leaders would need to convert to Islam, pay immense tribute to the Muslims, or face conquest.
Most people in the Byzantine Empire spoke Greek. Latin was the language of government until the reign of Heraclius (Heraklios) I in the early Seventh Century A.D., when it was officially changed to Greek as well.
The theme of Thrace was established in the early 7th century in the Byzantine Empire, as part of the administrative reorganization of the empire under the Emperor Heraclius. It was one of the original themes, or military provinces, that helped strengthen and defend the empire's borders.
A man named Principes. The most famous and probably most significant reformer of the Ancient Roman legions was Marius. However, various other Roman leaders, including Emperor Diocletian and Eastern Roman Emperor Heraclius, also reformed the legions. As to reorganizations of non-Roman legions, I don't know.
