The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are used throughout the Indian subcontinent, Southeast Asia and parts of East Asia. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.
Brahmic scripts descended from the Brahmi script. Brahmi is clearly attested from the 3rd century BCE during the reign of Ashoka, who used the script for imperial edicts, but there are some earlier epigraphy found on pottery in Porunthal in Kongu Nadu and in Sri Lanka. The short Brahmi inscriptions dated to the 6th century BCE from Porunthal in Kongu Nadu and the Sri Lankan Anuradhapura inscription from the 4th century BCE and published by Coningham et al. (1996).
Northern Brahmi gave rise to the Gupta script during the Gupta period, which in turn diversified into a number of cursives during the medieval period. Notable examples of such medieval scripts, developed by the 7th or 8th century, include Nagari, Siddham and Sharada.
The Siddhaṃ script was especially important in Buddhism, as many sutras were written in it. The art of Siddham calligraphy survives today in Japan. The tabular presentation and dictionary order of the modern kana system of Japanese writing is believed to be descended from the Indic scripts, most likely through the spread of Buddhism.
Southern Brahmi evolved into the Kadamba, Pallava and Vatteluttu scripts, which in turn diversified into other scripts of South India and Southeast Asia. Brahmic scripts spread in a peaceful manner, Indianization, or the spread of Indian learning. The scripts spread naturally to Southeast Asia, at ports on trading routes. At these trading posts, ancient inscriptions have been found in Sanskrit, using scripts that originated in India.
