The promotion of human rights is a fundamental principle of the United Nations, established in its founding documents and emphasized throughout its various missions and declarations. This principle is evident in key UN documents such as the Universal Declaration of Human Rights, adopted in 1948, which outlines the fundamental rights and freedoms that all individuals are entitled to, regardless of nationality, ethnicity, or religion.
