Brahmi script

Ashoka's edicts spread an Indian script that becomes the parent of Devanagari, Tamil and Thai.

Brahmi appears in Emperor Ashoka's rock and pillar edicts of the 3rd century BCE and marks vowels with diacritics attached to consonants. Its descendants, the Brahmic scripts, now write languages spoken by well over a billion people.
