Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services.
