The Imperial System of Honours and Awards is a scheme of honours bestowed on citizens or foreigners by the British monarch. This system has a long history, rooted in Roman traditions of awards for military service. Over the twentieth century the honours system has gradually evolved to recognise civilian service and other achievements.
Until 1975, the British Imperial system was the only system for recognition of the service of Australian citizens to Australia. Today, the Imperial system has been largely replaced by the Australian system, established in 1975. Imperial Honours continued to be awarded to Australians on the recommendation of some States until 1989. The Queen still bestows some honours personally.
