1901 The Imperial Tobacco Company was created through the amalgamation of thirteen British tobacco and cigarette companies compromising W. D. and H. O. Wills of Bristol (the leading manufacturer of the time), John Player and Sons (Player's) of Nottingham and 11 other independent family businesses, which were being threatened by competition from the United States in the form of James Buchanan Duke and his American Tobacco Company. The company was registered on 10 December to amalgamate various businesses of tobacco manufacturers. 
The company's first Chairman was William Henry Wills of the Wills Company. Subsequently the smaller companies in the group including Lambert and Butler, William Clarke and Son, Franklyn Davey, Edwards Ringer, J. and F. Bell and F. and J. Smith were absorbed by the larger, with Wills and Players eventually emerging as the UK market leaders.
