Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. 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. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. Credit union as a consumer cooperative operates on the principles of equality of all its members.
