Many historians have written about the impressive social achievement of the last Liberal Government which sat in Britain from 1905 to 1916. Prominent among them is Bentley Gilbert whose Evolution of National Insurance in Great Britain importantly expands. Maurice Bruce's excellent survey The Coming of the Welfare State. Much of this work has emphasized the political maneuverings for legislation which increased the economic security of millions of British citizens. This paper takes a different, supplementary approach. It is an attempt to understand the impact of the Liberals' social reform program on a part of the philanthropic community which had asssumed an important role in meeting the problems of poverty. The focus is on the provisions for social welfare made by voluntary and statutory agencies in order to clarify the beginnings of their successful partnership which today operates in the Welfare State. David Owen, in his monumental study of English philanthropy, has rightly characterized the modern role for voluntary agencies as “Junior Partner(s) in the Welfare Firm,” but he has wrongly stated that this role was recognized only after the First World War. The voluntary-statutory partnership in social welfare was formed during the Liberals' legislative revolution from 1906 to 1911: voluntarists who were affected by it understood its signficance for their work.The welfare measures of the post-Second World War Labour Government gave final recognition to the fact that in Britain social development was no longer to be the by-product of economic development, and that the State must plan comprehensively to meet social needs rather than filling in the gaps left by private effort. In a very real sense the proposals of the Fabians, Sidney and Beatrice Webb, given shape in this new age by a Fabian disciple, William Beveridge, became the foundation of British policy. But the social legislation enacted by the Labour Government was implanted in ground haphazardly prepared by previous measures which provided for specific needs, but often with little reference to related questions.
