Another early preservation event also occurred at Berkhamsted. In 1866, Lord Brownlow who lived at Ashridge, tried to enclose the adjoining Berkhamsted Common with steel fences in an attempt to claim it as part of his estate. In England from early Anglo-Saxon times, Common land was an area of land which the local community could use as a resource. Across England between 1660 and 1845, 7 million acres of Common land had been enclosed by private land owners by application to parliament. On the night of 6 March 1866, Augustus Smith MP led gangs of local folk and hired men from London's East End in direct action to break the enclosure fences and protect Berkhamsted Common for the people of Berkhamsted in what became known nationally as the Battle of Berkhamsted Common. In 1870, Sir Robert Hunter (later co-founder of the National Trust in 1895) and the Commons Preservation Society succeed in legal action that ensured protection of Berkhamsted Common and other open spaces threatened with enclosure. In 1926 the common was acquired by the National Trust.
