Our History online archive is being developed in co-operation with the Socialist History Society. The SHS was founded in 1992. Its members include many of Britain's leading socialist and labour historians, both academic and amateur. The SHS is the successor to the Communist Party History Group, established in 1946. The society is now entirely independent of all political parties and groups. It is engaged in, and seeks to encourage, historical studies from a Marxist and broadly-defined left perspective. The Communist Party Historians' (later: History) Group produced various series of publications between 1946 and 1991. The longest-running and most important of these was the series of short monographs Our History, which appeared roughly quarterly from 1956 onwards. The early pamphlets in this series were produced on a duplicating machine, but from 1969 onwards they were printed.
