Coptic was the language spoken by the native population of Egypt from about the third to the tenth century C.E. (after which Arabic began to supplant it). Sahidic and Bohairic were the most important of its many dialects. Syriac, a branch of the Aramaic language, was spoken in Syria and Mesopotamia from just before the beginning of the Christian era until it was eventually displaced by Arabic. Latin, the language of the Roman imperial system, was also the spoken language of many people throughout the western part of the Roman empire, especially in Italy and North Africa. Armenian was the spoken language of the ancient kingdom of Armenia; a 36-letter alphabet was created for it in about 406 C.E.
