The term wog is derived from golliwog:
The "Golliwogg" (later "Golliwog") is a character of children's literature created by Florence Kate Upton in the late 19th century, inspired by a blackface minstrel doll which Upton found as a child in her aunt's attic in Hampstead, North London. The character, depicted in the books as a type of rag doll, was reproduced, both by commercial and hobby toy-makers as a children's toy. The toy was known as a "golliwog", and had great popularity in North America, Britain, Europe and Australasia, into the 1960s. While home-made golliwogs were sometimes female, the golliwog was generally male. For this reason, in the period following World War II, the golliwog was seen, along with the teddy bear, as a suitable soft toy for a young boy.
The image of the doll has become the subject of heated debate. One aspect of the debate in its favor argues that it should be preserved and passed on as a cherished cultural artifact and childhood tradition, while opponents argue it should be retired as a relic of an earlier time when racism against those of African descent was blatant.
The word "golliwog" has from the 1950s onward been used as a term of racial abuse directed at black people. This has reduced the popularity and sale of golliwogs as toys. Manufacturers who have used golliwogs as a motif have either withdrawn them as an icon, or changed the name. There has been wide press coverage of incidents in which the term "golliwog" has been applied to a well-known personality.
