The Buddha is a titled used to refer to a man named “Siddharth Gautama”. It means Fully Awakened One. He was born in a region of what is now known as Nepal and was the person who created the religion of Buddhism. He lived from about 563 BC to about 483 BC.
He is also called Shakyamuni Buddha because he was a member of the Śākyan clan, the ruling class of an aristocratic republic in that region.
Buddhism originated in India, based on the teachings, of Siddhartha Gautama, later known as Gautama Buddha. A Buddha is one who is said to be awake to the truth of life.
Over the centuries his teachings spread from India to Central Asia, Tibet, Sri Lanka, Southeast Asia, China, Mongolia, Korea, Japan, and now Europe and North and South America. Theravada Buddhism is most common in South Asia; Mahayana further north. Buddhism exists in many different strands today, but all schools and sects share basic ideas. About seven percent of the people of the world are Buddhist.
While many people see Buddhism as a religion, others see it as a philosophy, and others as a way of finding reality.
