Francis M. Deng, the Representative of the UN Secretary-General on Internally Displaced Persons (1992-2004), developped these guidelines in 1998. It is a set of 30 recommendations, which define who Internally Displaced Persons (IDPs) are, outline the large body of existing international law protecting people’s basic rights, and describe the responsibility of states. Although not legally binding, they constitute a comprehensive minimum standard for the treatment of IDPs and are being applied by a growing number of states and institutions. They may also help empower IDPs themselves by providing them with information about their rights as citizens of their own country. Principle 23 is about the right to education.
