Founded in 1862, the company developed strong associations with Quaker philanthropy.[1] Throughout much of the 19th and 20th centuries, it was one of the big three confectionery manufacturers in the United Kingdom, alongside Cadbury and Fry, both also founded by Quakers.[2]

In 1981, Rowntree's received the Queen's Award for Enterprise for outstanding contribution to international trade.[3] In 1988, when the company was acquired by Nestlé, it was the fourth-largest confectionery manufacturer in the world.[4] The Rowntree brand continues to be used to market Nestlé's jelly sweet brands, such as Fruit Gums and Fruit Pastilles.
