The Anthropological Society of London (ASL) was founded in 1863 as an institutional home for those who disagreed with the Ethnological Society's politics (in terms of party loyalties, Stocking makes the political complexion of the ESL 75% Liberal to 25% Conservative, with the proportions reversed in the ASL). On the topic of race, the Ethnological Society retained views descending from Johann Friedrich Blumenbach, who had a five-race theory but was a monogenist, and from Prichard. The post-Darwin concept of human speciation was unacceptable to those forming the Anthropological Society.
