What happened
By the time the Chinese pilgrim Xuanzang traveled through India in the early 7th century CE, Buddhism, once dominant across much of the Gangetic plains, was already in visible decline: in Varanasi he found roughly 3,000 Buddhist monks but more than 10,000 non-Buddhists. UCLA historian Vinay Lal describes competing explanations for the disappearance that followed, including the withdrawal of royal patronage as regional Hindu kingdoms rose, absorption of Buddhist ideas into Hindu devotional practice, and the arrival of Islamic conquest in the early second millennium. World History Encyclopedia's account of Muhammad Ghori's Ghurid campaigns confirms the backdrop, noting his forces captured Bengal and defeated the last independent king of Kannauj in 1194 CE, sweeping through the same Bihar and Bengal region where Nalanda and Buddhism's other monastic strongholds still stood. By the 13th century, Buddhism had disappeared from India as a formal, organized religion.
Why it matters
Buddhism's disappearance from its homeland, even as it flourished from Sri Lanka to Japan, is one of the most striking facts in its history: a religion that reshaped Asia largely stopped being practiced in the country where it began, and it would take a 20th-century mass political and religious movement to bring organized Buddhism back to India in significant numbers.
How we know
Buddhism's decline is documented through the eyewitness travel account of the Chinese pilgrim Xuanzang, who personally observed the shrinking Buddhist population during his 7th-century journey through India, and through the historical record of Ghurid military campaigns into Bihar and Bengal in the 1190s, both analyzed by modern historians alongside the archaeological and textual record of Buddhist institutions that ceased to function in this period.
