When was buddism founded?
2500 years ago
Historians have differing opinions on the precise date of the Buddha's birth but it was around the year 500BCE. He was born into a noble family in Lumbini, an area that today lies in the South of Nepal.
Seddartha founded Buddism because he wanted to find the end of all human suffering. He realized that the cause of all human suffering is diseire. Wanting something is the cause of suffering, because if you don't get it or if it doesnt come to you, you suffer yourself. -Hope this is better help to you then the other answers.
