This document discusses the development of minority rights from past centuries to the present. It begins by examining definitions of the term "minority" that have been proposed, noting there is no universally accepted definition. It then discusses the need for minority rights protections given that minorities are often politically marginalized and vulnerable to discrimination. The document traces how minority rights developed after World War I through the League of Nations, and then the United Nations adopted further protections like the 1992 Declaration on the Rights of Persons Belonging to National or Ethnic, Religious and Linguistic Minorities. Key international legal instruments that protect minority rights are also identified.
