Instelling
The first International Congress of Anthropological and Ethnological Sciences was held in London in 1934, though a preliminary conference had been held the previous year in Basel at the invitation of the Royal Anthropological Institute of Great Britain and Ireland. It had first been muted in 1912 after the London Session of the International Congress of Americanists. The Congress was held every four years in different locations but merged officially with the International Union of Anthropological and Ethnological Sciences in 1968 which still holds Congresses every five years.
