“The foundation of the Chosŏn dynasty (1392- 1910), with its pronounced Neo-Confucian sympathies, brought an end to Buddhism's hegemony in Korean religion and upset this ideological status quo. Buddhism's close affiliation with the vanquished Koryŏ rulers led to centuries of persecution during this Confucian dynasty. While controls over monastic vocations and conduct had already been instituted during the Koryŏ period, these pale next to the severe restrictions promulgated during the Chosŏn dynasty. The number of monks was severely restricted—and at times a complete ban on ordination instituted—and monks were prohibited from entering the metropolitan areas. Hundreds of monasteries were disestablished (the number of temples dropping to 242 during the reign of T'aejong [r. 1401-1418]), and new construction was forbidden in the cities and villages of Korea. Monastic land holdings and temple slaves were confiscated by the government in 1406, undermining the economic viability of many monasteries. The vast power that Buddhists had wielded during the Silla and Koryŏ dynasties was now exerted by Confucians. Buddhism was kept virtually quarantined in the countryside, isolated from the intellectual debates of the times. Its lay adherents were more commonly the illiterate peasants of the countryside and women, rather than the educated male elite of the cities, as had been the case in ages past. Buddhism had become insular, and ineffective in generating creative responses to this Confucian challenge.”
