Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Members of credit unions place in credit unions usually free fund balances, ie those that remain after expenses devoted to education of children, the acquisition of new properties, additional pension benefits, etc. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. Credit Union - a non-profit financial institution specialized in mutual financial assistance by providing savings and credit services to their members.
