Election monitoring involves the observation of an election by one or more independent parties, typically from another country or from a non-governmental organization (NGO). The monitoring parties aim primarily to assess the conduct of an election process on the basis of national legislation and of international election standards. There are national and international election observers. Monitors do not directly prevent electoral fraud, but rather record and report instances of suspicious practices. Election observation increasingly looks at the entire electoral process over a long period of time, rather than at election-day proceedings only. The legitimacy of an election can be affected by the criticism of monitors, unless they are themselves seen as biased. A notable individual is often appointed honorary leader of a monitoring organization in an effort to enhance legitimacy of the monitoring process. The first monitored election was that of an 1857 plebiscite in Moldavia and Wallachia (current Romania) that was monitored by most of the major European powers. Election monitoring was uncommon until after World War II. During the 1960s, less than 10% of elections were monitored. Election observation activities have expanded significantly following the end of the Cold War, along with the development of international standards on the conduct of democratic elections and the process of monitoring elections by both international and domestic observing organizations. By the 2000s, about 80% of all elections were observed. International organizations such as the Organization of American States, the Organization for Security and Co-operation in Europe (OSCE), the European Union, the Commonwealth Secretariat, the Council of Europe, and the African Union regularly deploy monitoring teams. The United Nations no longer provides monitoring services; instead, it focuses on electoral assistance. Individual governments also participate in monitoring efforts, generally under the umbrella of an international organization.
