Hardwicke Rawnsley he wrote to "The Times" protesting against Britain's high tax on the importation of French wine, which he saw as unfair and as contributing to rural poverty in France. To protect the countryside from damaging development, Rawnsley, building on an idea propounded by Ruskin, conceived of a National Trust that could buy and preserve places of natural beauty and historic interest for the nation. The Trust became a reality in 1895; its co-founders were Rawnsley, Octavia Hill and Sir Robert Hunter. Until his death, Rawnsley worked as Honorary Secretary to the Trust. He was responsible for the campaign to raise
National Trust for Places of Historic Interest or Natural Beauty under the Charities Act 2006. Its formal purpose is: The trust was founded on 12 January 1895 by Octavia Hill (1838–1912), Sir Robert Hunter (1844–1913) and Hardwicke Rawnsley (1851–1920), prompted in part by the earlier success of Charles Eliot and the Kyrle Society. In the early days, the trust was concerned primarily with protecting open spaces and a variety of threatened buildings; its first property was Alfriston Clergy House, and a decorative cornice there may have given the trust its sprig of oak symbol. The trust's first nature reserve was Wicken Fen, and its first archaeological monument was White Barrow.
