What happened
Adi Shankara, whom the Stanford Encyclopedia of Philosophy dates to the 8th century CE, with alternative scholarly proposals ranging from about 700 to 750 CE, became the most influential systematizer of Advaita Vedanta, the non-dualist school built on the Upanishads. His central claim, in the Encyclopedia's summary, was that Atman, the individual self, is pure non-intentional consciousness, nondual and numerically identical with Brahman, the single ground underlying all objects; everything experienced as separate or plural, in this view, is maya, illusion laid over one undivided reality. Shankara did not invent Advaita Vedanta, which predated him, but became its most authoritative and enduring voice through commentaries on the Upanishads, the Brahma Sutras, and the Bhagavad Gita. Tradition credits him with founding four mathas, monasteries, at Sringeri in the south, Puri in the east, Dwarka in the west, and Badrinath/Joshimath in the north, each entrusted with one Veda, to institutionalize and spread his teaching across the subcontinent; historians note that some scholars attribute the full four-matha system to a later 14th-century figure, Vidyaranya, working to promote Shankara's legacy rather than to Shankara himself.
Why it matters
Shankara's Advaita Vedanta became, in the Stanford Encyclopedia's words, the most authoritative philosopher of Advaita Vedanta and continues to influence virtually all contemporary lineages, giving Hindu philosophy its most durable single framework and providing the intellectual foundation that 19th-century reformers like Vivekananda would later present to the world as the essence of Hindu thought.
How we know
Shankara's authorship is established through his surviving commentaries (Bhashya) on the Upanishads, Brahma Sutras, and Bhagavad Gita, though modern scholarship, per the Stanford Encyclopedia, treats most of the roughly 300 texts popularly attributed to him as the work of later followers rather than Shankara himself, complicating exact biographical certainty.
