The bowler hat, also known as a bob hat, derby (US), billycock or bombín, is a hard felt hat with a rounded crown originally created in 1849 for the British soldier and politician Edward Coke, the younger brother of the 2nd Earl of Leicester. The bowler hat was popular with the working class during the Victorian era, and later on with the middle and upper classes in the United Kingdom and the eastern United States. Later in the United Kingdom, it would come to be worn as civilian work dress by former officers of the Queen's Guard. In Bolivia, women of Quechua people have worn bowler hats since the 1920s when British railway workers introduced them there.
