Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. 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.
