The United Nations designates specific International decades as occasions to mark particular events or topics in order to promote, through awareness and action, the objectives of the Organization. Usually, it is one or more Member States that propose these observances and the United Nations General Assembly establishes them with a resolution. Some of them may be later adopted by the General Assembly.
