The Universal Declaration of Human Rights (UDHR) is a cornerstone of international human rights law. Adopted in 1948, it established universal principles of human dignity, equality, and non-discrimination that continue to shape global norms and legal frameworks. The UDHR's impact is far-reaching, influencing national constitutions, international treaties, and human rights institutions worldwide. While not legally binding, its principles have gained the status of customary international law, providing a common standard for promoting and protecting human rights across cultures and nations.
