With regard to the internally displaced, the United Nations has worked towards the development of a normative framework for the protection and assistance of the internally displaced — the Guiding Principles on Internal Displacement.48 Standards have existed for refugees since 1951, but the Guiding Principles are the first international standards for the internally displaced.
Desde 1951 existen normas sobre los refugiados, si bien los Principios rectores constituyen las primeras normas internacionales en favor de los desplazados internos.
