Siddhartha Gautama, also known as Buddha, is the founder of Buddhism. He was born in India in the 6th century BCE, grew up in a royal family, and left home to seek spiritual enlightenment in his adult years. He went through a long period of asceticism and meditation, and finally achieved enlightenment under a Bodhi tree, becoming the Buddha.

Buddha's teachings emphasize the middle path, avoiding extreme pleasure and pain, and seeking inner peace and wisdom. He put forward doctrines such as the 'Four Noble Truths' and the 'Eightfold Path,' teaching people how to overcome suffering and achieve inner peace and liberation.

Buddha's teachings spread rapidly in India and became a major religious belief. Buddhism also spread widely in China, Southeast Asia, and other regions. Buddha's teachings are known for their universality and practicality and have become an important philosophy and religious belief worldwide.
