Buddhism started in India around 500 B.C and was started by a man named Siddhartha (Buddha). Buddhism started because Siddhartha as a kid always wondered why people suffered so much and he hated to see people so sad all of the time. A holy man believed and told Siddhartha's dad that Buddha would be a spiritual leader. 29 years later Buddha made the religion Buddhism and started to teach people about it. Buddha convinced people that they should follow a path to seek light in their life. This was called " Middle way". The Middle Way path was a way for people to see what life was all about and to make them feel happy. Buddha left his castle to help others who were sick or needed help. Once Buddha started to teach Buddhism, the religion started to spread from different regions. This happened because when all of the merchants went to trade , they taught people the teachings and ways of Buddhism. Eventually the religion spread to Southeast Asia, Korea, Japan, and China. Buddha taught the " Four - Noble Truths" to help people end their suffering so sooner or later they can reach Nirvana. Buddhism is a polytheistic religion because people only believed in Buddha and not any other God. Buddha taught Buddhism because he wanted others to be enlightened and be happy. Buddha also taught people that when you do something good , something will pay you back in return and that is called Karma. He also taught that when you do something bad you won't get anything back in return this is called Dharma. Buddha then later died and until this day people still follow his religion and they still praise the great lord Buddha.
