 Virtually all regional Basque rural sports have their origin in the two main historical occupations, the or "baserritarra" (farmer) and "arrantzalea" (fisher), with a larger percentage hailing from the rural background.The sociological changes in the Basque Country have led many of these becoming technically obsolete in the 19th and 20th century.Few continue to exist as rural or marine activities connected to everyday life and have become rare but many have managed to transform themselves into popular sports instead, some of which have become extremely popular.
