Ashoka becomes the last major ruler of the Mauryan dynasty. Chronology is debated in scholarship; major references commonly place his reign within the late 3rd century BCE (often given as c. 269–232 BCE or similar ranges).
Ashoka’s campaign against Kalinga—later highlighted in his own inscriptions as catastrophic in human cost—becomes the pivotal turning point associated with his public embrace of dharma and rejection of aggressive conquest.
An early Ashokan inscription at Kandahar (in Greek and Aramaic) reflects imperial communication in the northwest and is often treated as among the earliest-known Ashokan edicts.
Ashoka’s Minor Rock Edicts—among the earliest Ashokan proclamations in an Indian language written in Brahmi—are commonly dated to the 11th year of his reign.
Ashokan dedicatory inscriptions at the Barabar Hill Caves record royal patronage granted to the Ajivika community; these inscriptions are commonly dated to specific regnal years, including the 12th year.
The Major Rock Edicts expand and systematize Ashoka’s public policy of dhamma (ethical governance), spreading instructions on administration, moral conduct, and religious tolerance across the empire.
Major Rock Edict 13 is notable for referencing several Hellenistic kings (e.g., Antiochus II, Ptolemy II, Antigonus II, Magas, Alexander of Epirus), anchoring aspects of Ashoka’s chronology and signaling diplomatic awareness beyond India.
The Minor Pillar Edicts (including the Schism Edict and Queen’s Edict) represent an early phase of Ashoka’s pillar inscriptions, closely associated with the consolidation of his moral-administrative program.
Additional Barabar inscriptions attributed to Ashoka are dated to later regnal years (including the 19th), showing continuing royal support for Ajivikas and the ongoing development of the rock-cut cave tradition under Mauryan patronage.
Sri Lankan chronicles and later tradition credit Ashoka’s circle with dispatching Mahinda (Mahendra) to Sri Lanka, where the mission converts King Tissa and helps establish Buddhism as a major religious tradition on the island.
Theravada tradition places a Third Buddhist Council under Ashoka (often dated to about 247 BCE in that tradition), associated with resolving doctrinal disputes and later missionary activity narratives.
The Major Pillar Edicts—a mature phase of Ashoka’s inscriptional program—are generally dated to the 26th–27th regnal years, reflecting late-reign emphasis on governance, ethics, and administrative oversight.
Ashoka’s death marks the end of the reign of the Mauryan Empire’s last major emperor; major references commonly place this around the early 230s BCE (often c. 232 BCE, though alternate scholarly ranges exist).
