Nakaeia allowed two San Francisco trading firms to operate, Messrs. Crawford and Messrs. Wightman Brothers, with up to 12 Europeans resident on islands of the atolls. The presence of the Europeans, and the alcohol they traded to the islanders, resulted in periodic alcoholic binges that only ended with Nakaeia making tapu (forbidding) the sale of alcohol. During the 15 or so days that Stevenson spent on Butaritari the islanders were engaged in a drunken spree that threatened the safety of Stevenson and his family. Stevenson adopted the strategy of describing himself as the son of Queen Victoria so as to ensure that he would be treated as a person who should not be threatened or harmed.
