Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. 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). Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. 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. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity.
