First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee.
