Brahmi script in the context of "Brahmic scripts"

An abugida (/ˌɑːbuːˈɡiːdə, ˌæb-/ ; from Geʽez: አቡጊዳ, 'äbugīda)—sometimes also called an alphasyllabary, neosyllabary, or pseudo-alphabet—is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, like a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional. In less formal contexts, all three types of script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of a consonant and a vowel.

Related concepts were introduced independently in 1948 by James Germain Février (using the term néosyllabisme) and David Diringer (using the term semisyllabary), and in 1959 by Fred Householder (introducing the term pseudo-alphabet). The Ethiopic term "abugida" was chosen as a designation for the concept in 1990 by Peter T. Daniels. Faber suggested "segmentally coded syllabically linear phonographic script"; William O. Bright used the term alphasyllabary; and Gnanadesikan and Rimzhim, Katz, & Fowler suggested aksara or āksharik.

The Edicts of Ashoka are a collection of more than thirty inscriptions on the Pillars of Ashoka, as well as boulders and cave walls, attributed to Emperor Ashoka of the Maurya Empire who ruled most of the Indian subcontinent from 268 BCE to 232 BCE. These inscriptions were dispersed throughout the areas of modern-day India, Bangladesh, Nepal, Afghanistan and Pakistan, and provide the first tangible evidence of Buddhism. The Edicts are the earliest written and datable texts from India, and, since they were inscribed on stone, we have the added benefit of having them exactly as they were originally inscribed. Earlier texts, such as the Vedic texts, were all composed and handed down orally until later dates.

Ashoka used the expression Dhaṃma Lipi (Prakrit in the Brahmi script: 𑀥𑀁𑀫𑀮𑀺𑀧𑀺, "Inscriptions of the Dharma") to describe his own Edicts. The edicts describe in detail Ashoka's policy on dhamma, an earnest attempt to solve some of the problems that a complex society faced. According to the edicts, the extent of his promotion of dhamma during this period reached as far as the Greeks in the Mediterranean region. While the inscriptions mention the conversion of Ashoka to Buddhism, the dhamma that he promotes is largely ecumenical and non-sectarian in nature. As historian Romila Thapar relates:

Vasudeva II (Middle Brahmi script: Bā-zo-de-o Sanskritzied to "Vasudeva") was a Kushan emperor who ruled c. 275–300. He was probably the successor of Kanishka III and may have been succeeded by an emperor named Shaka Kushan.

Vasudeva II probably only was a local ruler in the area of Taxila, in western Punjab, under the suzerainty of the Gupta Empire.

Sutra (Sanskrit: सूत्र, romanized: sūtra, lit. 'formula') in Indian literary traditions refers to an aphorism or a collection of aphorisms in the form of a manual or, more broadly, a condensed manual or text. Sutras are a genre of ancient and medieval Indian texts found in Hinduism, Buddhism and Jainism.

In Hinduism, sutras are a distinct type of literary composition, a compilation of short aphoristic statements. Each sutra is any short rule, like a theorem distilled into few words or syllables, around which teachings of ritual, philosophy, grammar, or any field of knowledge can be woven. The oldest sutras of Hinduism are found in the Brahmana and Aranyaka layers of the Vedas. Every school of Hindu philosophy, Vedic guides for rites of passage, various fields of arts, law, and social ethics developed respective sutras, which help teach and transmit ideas from one generation to the next.

Simuka (Brahmi:𑀲𑀺𑀫𑀼𑀓, Si-mu-ka) was an ancient Indian king belonging to the Satavahana dynasty, which ruled the Deccan region. He is mentioned as the first king in a list of royals in a Satavahana inscription at Nanaghat. In the Puranas, the name of the first (Satavahana) king is variously spelt as Shivmukha, Sishuka, Sindhuka, Chhismaka, Shipraka, Srimukha, etc. These are believed to be corrupted spellings of "Simuka", resulting from copying and re-copying of manuscripts.

Based on available evidence, Simuka cannot be dated with certainty. According to one theory, he lived in 3rd century BCE; but he is generally thought to have lived in the 1st century BCE. Epigraphical evidence strongly suggests a 1st-century BCE date for Simuka: Simuka seems to be mentioned as the father the acting king Satakarni in the Naneghat inscription dated to 70-60 BCE, itself considered on palaeographical grounds to be posterior to the Nasik Caves inscription of Kanha (probably Simuka's brother) in Cave 19, dated to 100-70 BCE. Recent analysis of sources puts Simuka's reign possibly around 120 - 96 BCE.
