First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties. 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. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate.
