First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Credit union services are available only to its shareholders. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. Since the early 80's started the process of consolidation of credit unions, leading to a decrease in their number with a simultaneous increase in the total number of members. Over 30% of the assets of credit unions are investments in government securities, certificates of deposit of banks and savings loan associations, as well as in the parent credit unions, and other risk-free investments. 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 appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others.
