In the 19th century a number of groups in Britain actively promoted and followed meat-free diets. Key groups involved in the formation of the Vegetarian Society were members of the Bible Christian Church, supporters of the Concordium, and readers of the Truth-Tester journal.
Bible Christian Church 
The Bible Christian Church was founded in 1809 in Salford by Reverend William Cowherd after a split from the Swedenborgians. One distinctive feature of the Bible Christians was a belief in a meat-free diet, or ovo-lacto vegetarianism, as a form of temperance.
Concordium (Alcott House) 
The Concordium was a boarding school near London on Ham Common, Richmond, Surrey, which opened in 1838. Pupils at the school followed a diet completely free of animal products, known today as a vegan diet. The Concordium was also called Alcott House, in honor of American education and food reform advocate Amos Bronson Alcott.
Truth-Tester and Physiological Conference, 1847 
The Truth-Tester was a journal which published material supporting the temperance movement. In 1846 the editorship was taken over by William Horsell, operator of the Northwood Villa Hydropathic Institute in Ramsgate, Kent. Horsell gradually steered the Truth-Tester towards promotion of the 'Vegetable Diet'. In early 1847 a letter to the Truth-Tester proposed formation of a Vegetarian Society. In response to this letter, William Oldham held what he called a "physiological conference" July 1847 at Alcott House. Up to 130 attended, including Bible Christian James Simpson, who presented a speech. The conference passed a number of resolutions, including a resolution to reconvene at the end of September.
Ramsgate Conference, 1847 
On September 30, 1847 the meeting which had been planned at the Physiological Conference took place at Northwood Villa Hydropathic Institute in Ramgate. Joseph Brotherton, Member of Parliament for Salford, and a Bible Christian chaired. Bible Christian James Simpson was elected president of the society, Concordist William Oldham elected treasurer, and Truth-Tester editor William Horsell elected secretary. The name 'Vegetarian Society' was chosen for the new organization by a unanimous vote.
After Ramsgate 
Current work 
In the 20th century, the Society's work became geared primarily towards the provision of advice and education to individuals, educational establishments and community groups. The Vegetarian Society also acts as a pressure group with the aim of influencing food producers to remove non-vegetarian ingredients such as gelatine or cheese produced using animal rennet from their products. Manufacturers can apply for their products to be accredited with the Society's trademarked seedling symbol, which has strict criteria, including the use of free range eggs, which other V symbols may not include. They also campaign strongly against the labelling of products containing fish as vegetarian, (particularly by restaurants) and negatively highlighting celebrities who claim to be vegetarian but eat fish. The Society also maintains a regularly updated list of products which are not vegetarian.
