Buddhism is a tradition that focuses on personal spiritual development. Buddhism began around the 5th century BCE with the teachings of Siddhartha Gautama (‘the Buddha’). The largest populations are in China and Japan, and in many other south-east asian countries Buddists form a majority of the population. (Information sources: BBC website and Wikipedia)
