Young Researchers of Serbia (YRS) is a non-profit, non-political NGO that gathers young people around common interests, ideas and goals. YRS aroused from the research movement at Valjevo in 1969, but in 1976 was officially established as a network of organizations, societies, clubs and sections with research programmes, gathered around the coordinative office on the republic level in Belgrade. Through its history, the number of members changed, but there were over 50 different organizations taking part. In the 90’s YRS leaves the organizational form of vertical relationships following the current direction of civil sector development. Today YRS represents the organization on the national level and is unites three thematically different but interconnected sectors – Youth Sector, Voluntary Service of Serbia and Environmental Protection and Conservation Sector.
