The story will pick out the key events for the formation and development of the East of England Co-operative, but will obviously relate the East of England to its wider background within the national Co-operative Movement. Thus we deal with the social and political background to the formation of the local co-operative societies. Three societies Colchester, Ipswich and Norwich, originally independent, formed the backbone of the East of England Co-operative Society. This lecture follows the development of the three societies and their ultimate formation of the East of England Co-operative Society. It deals with the rise of the societies to the peak position in 1945 and the gradual decline during the 1970’s and 80’s. Then follows the recovery in the current century where co-operation has become a major topic following the Covid 19 crisis.
