There are two major divisions of Buddhism. The Sthavira; which was more orthopraxic; and the Mahasamghika that tended to rely more on texts. Each developed into different school; of which there are many sub-divisions. At present; however; three major forms survive: one Sthavira; known as Theravada; in South East Asia; and two Mahayana; namely the Chinese and Tibetan traditions. The Theravada tradition spread from India to Sri Lanka and Burma in the 3rd century BCE; and from there to Yunnan in southwest China; Thailand; Laos; Cambodia; South Vietnam and Indonesia.
