A highwayman was a robber who preyed on travelers, particularly one who traveled by horse; those who robbed on foot were called footpads. Mounted robbers were widely considered to be socially superior to footpads. Such robbers operated in Great Britain and Ireland from the Elizabethan era until the early 19th century. The word highwayman is first attested from the year 1617; other euphemisms included "knights of the road" and "gentlemen of the road." In the 19th century American West, highwaymen were known as road agents. In the same time period in Australia, they were known as bushrangers.
