Until now Serbian history has claimed that there are no living descendants of the medieval Nemanjic dynasty. After a complex research the existence of 25 families that have their roots in Vukan Nemanjic and 108 families from Stefan the First-Crowned was determined and documented. The research looked at the bilinear descendants of this lineage. Except in the scientific research can be viewed in a broad social context. At the domestic and international level Serbia could establish a completely new order of its own organization but also relations with countries in Europe and the world observing the living descendants of its most important ruling family.
