Buddhism (, ) is the world's fourth-largest religion with over 520 million followers, or over 7% of the global population, known as Buddhists. Buddhism encompasses a variety of traditions, beliefs and spiritual practices largely based on original teachings attributed to the Buddha (born Siddhārtha Gautama in the 5th or 4th century BCE) and resulting interpreted philosophies. It originated in ancient India as a Sramana tradition sometime between the 6th and 4th centuries BCE, spreading through much of Asia. Two major extant branches of Buddhism are generally recognized by scholars: Theravāda (Pali: "The School of the Elders") and Mahāyāna (Sanskrit: "The Great Vehicle").
