Classic children's books in a Cambridge University archive are set to be labelled with 'trigger warnings' for 'harmful content relating to slavery, colonialism and racism'. 

Researchers are reviewing more than 10,000 books and magazines to expose offensive authors after campaigners demanded teachers censor racial slurs when reading Harper Lee's To Kill A Mockingbird.

With other modern classics like Little House On The Prairie and the works of Dr Seuss dubbed as potentially harmful, Femail has examined other children's texts which have come under fire. 

Criticism includes that of Rudyard Kipling's The Jungle Book which was slammed for it's 'colonial' depiction of animals and Roald Dahl's Matilda which was dubbed transphobic for it's portrayal of masculine Miss Trunchbull. 

Here, FEMAIL takes a look at what other much-loved bedtime stories could be at risk of being 'cancelled'. 

THE JUNGLE BOOK

Rudyard Kipling's 1894 work The Jungle book is a collection of stories set in a forest in India with a cast of animals and 'man-cub' Mowgli, who is raised in the jungle by wolves. 

While the book and it's many adaptions have been a childhood favourite for many, the novel itself has come under fire for forming part of the construction of 'colonial English national identity'. 

In 2001, academic Jopi Nyman argued that the book's depiction of Indian children and animals contribute 'imagining of Englishness as a site of power and racial superiority'.  

He argued that all animals are not portrayed equally in the book and the author depicts 'colonial animals as racialised' while characters such as the 'White Seal' promote the 'true English identity'.  

Kipling's 1899 poem The White Man's Burden has been criticised in modern times for advocating colonialism and portraying other races as inferior.  

In 2012, former England footballer John Barnes said that literature like The Jungle Book has instilled bigotry in the minds of generations of British children. 

Speaking to students at Liverpool University, he said: 'Over the last 200 years we have had negative images of black people.'
