Honorary citizenship is a status bestowed by a country on a foreign individual whom it considers to be especially admirable or otherwise worthy of the distinction.
Historically, many states limited citizenship to only a proportion of their population, thereby creating a citizen class with political rights superior to other sections of the population, but equal with each other. The classical example of a limited citizenry was Athens where slaves, women, and resident foreigners (called metics) were excluded from political rights. The Roman Republic forms another example (see Roman citizenship).
In Germany honorary citizenship is awarded by cities, towns and sometimes federal states. The honorary citizenship ends with the death of the honoured, or, in exceptional cases, when it is taken away by the council or parliament of the city, town, or state. In the case of war criminals, all such honours were taken away by "Article VIII, section II, letter i of the directive 38 of the Allied Control Council for Germany" on October 12, 1946. In some cases, honorary citizenship was taken away from members of the former GDR regime, e.g. Erich Honecker, after the collapse of the GDR in 1989/90.
Che Guevara was made an honorary citizen of Cuba by Fidel Castro for his part in the Cuban Revolution. Embarking on fomenting revolutions in other countries, Che Guevara, in his farewell letter to Fidel, gave up all his official ties to Cuba, including citizenship.
To mark the occasion of the 50th anniversary of the first successful ascent of Everest the Nepalese government conferred honorary citizenship upon Hillary at a special Golden Jubilee celebration in Kathmandu, Nepal. He was the first foreign national to receive that honour.
