It soon became the largest union of coopers in London, and by 1850 had 460 members.
In 1894, it was re-established as the United Society of Coopers (London), with 700 members.
In 1919, it became the National Association of Coopers, hoping to expand and rival the Mutual Association, but in 1926 the two unions agreed to work together to form the Coopers' Federation of Great Britain.
[1] George William Harrison, secretary of the union, became the first secretary of the federation, but he was removed from office a year later due to embezzling money collected to support the 1926 UK miners' strike.
[2] In 1947, the union merged with the Leith, Edinburgh and District Society of Coopers, to form the National Trade Union of Coopers, which retained membership of the federation.
