A self-proclaimed monarchy is established when a person claims a monarchy without any historical ties to a previous dynasty. In many cases, this would make them a pretender to the throne. The self-proclaimed monarch may be of an established state, such as Zog I of Albania, or of a micronation, such as Leonard Casley of Hutt River, Western Australia.
