This category is for child monarchs who were deposed before reaching the age of majority in their culture. Before modern times this generally seems to have been around age 15 or 16. It also applies to child monarchs who abdicated, since, as minors, they would have been deemed incapable of making such a decision independently. "Ruler" in this category refers to someone holding an office of sovereign and temporal authority. See Category:Child monarchs for more definition and discussion.
