Buddhism is a non-theistic "philosophical and spiritual doctrine" belonging to the Dharmic family, derived from Brahmanism and, according to Vedicism, from the Nástika type. It comprises a variety of traditions, religious beliefs and spiritual practices mainly attributable to Buddha Gautama. Buddhism originated in India between the sixth and fourth centuries BC. C., from where it spread to much of East Asia and declined its practice in the country of origin during the Middle Ages. There are two main branches of Buddhism: Theravada (School of the Elders) and Mahāyāna (The Great Way). Buddhism is the fourth most important religion in the world with more than 500 million followers, that is, 7% of the world population.
Buddhism was developed from the teachings spread by its founder Siddhartha Gautama, around the 5th century BC. C. in the northeast of India. The details of Buddha's life are mentioned in ancient Buddhist texts, in which there are marked inconsistencies in the details of his life, although there is no precision about the dates in which he experienced a rapid expansion to become the predominant religion in India in the third century a. In this century, the Indian emperor (Aśoka) makes him the official religion of his enormous empire, sending embassies of Buddhist monks to all the world known then. It will not be until the seventh century AD. C. when it will begin a decline in its homeland, although by then it had already expanded to many territories. By the thirteenth century it had reached its near complete demise from India, but it had spread successfully through most of the east of the Asian continent. Buddhism has helped in the dissemination of language and the adoption of humanist and universalist values. It is an important philosophy in the Far East where it is present in all of its countries. Since the twentieth century it has also expanded throughout the rest of the world. Lacking a supreme deity and at the same time showing its salvific and universal character, it has also been described as a transcultural phenomenon, philosophy or method of spiritual transformation. Buddhism is, in number of followers, one of the largest "religions" on the planet. It contains a wide variety of schools, doctrines and practices that have historically been classified into Theravāda, Mahāyāna and Vajrayāna Buddhism.
