The Office for Democratic Institutions and Human Rights (ODIHR) is the principal institution of the Organization for Security and Cooperation in Europe (OSCE) dealing with the "human dimension" of security. The office, originally named Office for Free Elections, was created in 1990 by the Charter of Paris and established in 1991. The name of the office was changed in 1992 to reflect the broadened mandate it received at the 1992 Helsinki Summit. The ODIHR, based in Warsaw (Poland) is active throughout the 57 participating States of the OSCE. It assists governments to live up to their commitments as participating States of the OSCE in the areas of elections, human rights, democracy, rule of law, and tolerance and non-discrimination. The ODIHR is best known for its role in observing elections. It has observed over 150 elections across the OSCEregion and has deployed some 35,000 observers.
