The United Kingdom is home to a widespread and diverse co-operative movement, with over 3 million individual members. Modern co-operation started with the Rochdale Pioneers' shop in the northern English town of Rochdale in 1844. Co-operativesUK is the central membership organisation for co-operative enterprise throughout the UK. This is a co-operative of co-operatives: a co-operative federation. Most kinds of co-operatives are eligible to join Co-operativesUK.
