Chan, from Sanskrit dhyāna, is a Chinese school of Mahāyāna Buddhism. It developed in China from the 6th century CE onwards, becoming dominant during the Tang and Song dynasties. After the Yuan, Chan more or less fused with Pure Land Buddhism.
Chan spread south to Vietnam as Thiền and north to Korea as Seon, and, in the 13th century, east to Japan as Zen.
