Prohibitions in both international documents and national legislation of the countries play a role in solving the problem, but not enough. As can be seen, in most cases, early marriage is the result of traditions and ways of thinking. It is this way of thinking that creates gender stereotypes, and gender stereotypes create gender inequality by being supported by gender roles.
