The party was founded in December 2006 by Jasmijn de Boo, a Dutch national, of Kennington, London, and Shaun Rutherford of Milford Haven, Wales, as Animals Count![3] The party was registered with the Electoral Commission on 22 January 2007.[4]
In October 2010, Vanessa Hudson was elected as party leader. In 2013, the party changed its name from Animals Count! to the Animal Welfare Party.[5]
In June 2013, Hudson joined leaders from other animal protection parties from across Europe in a meeting in The Hague organised by the Animal Politics Foundation of the Netherlands.[6] At this meeting the animal protection parties of the Netherlands, Spain, Portugal, Germany, Denmark, Italy, Turkey and the UK discussed ways in which they could work together more effectively. Later that month, Hudson announced that the Animal Welfare Party would stand in the London region in the 2014 European Parliament elections. It was one of seven European animal protection parties contesting the 2014 European elections with the aim of returning dedicated representatives for animals to the EU Parliament.[7] This European group of parties became known informally as the EuroAnimal7 and included PvdD of The Netherlands, PACMA of Spain, PAN of Portugal, Partei Mensch Umwelt Tierschutz of Germany, Djurens Parti of Sweden, and Animal Party Cyprus.
In September 2017, the party gained its first elected representative after Alsager Town Councillor Jane Smith defected from the Green Party to the AWP.[8]
