Old Tibetan refers to the earliest attested form of Tibetan language, reflected in documents from the adoption of writing by the Tibetan Empire in the mid-7th century to the early 9th century. In 816 CE, during the reign of Tibetan King Sadnalegs, literary Tibetan underwent comprehensive standardization, resulting in Classical Tibetan.
