United Kingdom Society of Amalgamated Smiths and Strikers

The United Kingdom Society of Amalgamated Smiths and Strikers was a trade union representing foundry workers in the United Kingdom.
The union was founded in 1886 and was a founder of the Federation of Engineering and Shipbuilding Trades in 1891. By the following year, it already had 2,200 members, but growth stalled, and by 1910 this had only increased to 2,731. However, it grew rapidly during World War I and by 1920 had more than 14,000 members. That year, it merged with the Amalgamated Society of Engineers and other smaller unions to form the Amalgamated Engineering Union.
